A good classic.

RH levels are fine, ranging between 35 and 45%. I've got to say, something changed between today and yesterday. Leaves have stopped falling, and the affected leaves don't feel like wilting on touch anymore. Instead, they're stiffer and harder on touch, and they're perking up again like nothing ever happened. The only thing i changed is that yesterday i added 0.25ML/LT Cal-Mag. I stopped feeding the Cal-Mag when people in the forum said it was already present in the biogrow and bloom powders, and that's when the N / Chlorine issue showed up. I'll see in the coming days how she goes with 0.5ML/LT Cal-Mag each feeding (except for Enhancer Feeding day). If the plant stops her madness and leaves stop falling, i probably figured out what the real Deficiency here is: either Magnesium or Manganese. If she doesn't.. I'll just pray Jah to help me reach Harvest day. Cheers!

Day 29, aka start of Week 4 flowering. Instead of mounting supports for the plant, i've tied Highlander to herself, twice. It's basically a lighter version of the nets used outdoors to contain a tree. Instead of placing a net above the canopy, i've tied the whole plant with a string, circling it all. I've also ordered the supports and they should arrive in a week or so. Feeding today was a bit different. I've fucked up with the PH down, so i had to use a bit of PH up. Fed with PH 6.4, couldn't bring it to 6.5 as i had little time to. Runoff at 6.4. The supposed Chlorine issue is rapidly spreading towards other, upper leaves. I'm not sure if it is chlorine, or if it's a deficiency caused by the flush. Either way, i'm just hoping she reaches 9th week without leaving a trail of leaves. To be sure, i added just 0.5ML/LT of Cal-Mag-Micro. The yellowing looks much more like a deficiency now. Hope it's not chlorine and i can fix it with Enhancer and some extra Cal-Mag here and there. I'll keep the dosages VERY low. Meanwhile, canopy has totally a different feel. Stretch is completely over. Plant's structure reaches 83cm, 53cm without the pot. As I'm Sal said, plant put on about 80% of stretch, as i started 12-12 and she was 30-35cm. The buds are starting to take shape, trichome production is amazing for being this early. What i'm reeeeally surprised about this strain is the low smell she emanates. Opening the tent doesn't blast your nose, it just smells.. grassy. But if you dare to touch one bud.. MAN, that's a strong smell. Pine scented, pungent, some citrus i can't recon. Who knows if she'll explode in smell later in the blooming phase, but as of now i'm really satisfied with it: it's super ninja. I guess it's time for a couple of pics. Highlander's Structure: Sorry about the quality of this pic, camera didn't cooperate. Highlander's Canopy: Highlander's colas, thickening: Highlander's flower close up: Highlander's Chlorine/Nutrient issues: What do you think about the leaf issues? Any thoughts about it? Had something similar before? Please share your experiences, i need to know how to treat it. Until next week.. Peace!

I'll be taking a chair to see those. Got a GSC from CanapaMundi, if you seed a cookie i'll be watching closely. A good opportunity to learn more on "her family", lol. Was Spannabis good? Had good vibes? There's spannabis in madrid too, maybe worth visiting.

They are beautiful man, recovered perfectly from those issues you had. Well done, can't wait to see your harvest!

Day 77, aka Day 22 Bloom. I guess it's time for an update. Issues As of today, i see 1-2 leaves falling per day. It's not bad, but it's not optimal. Leaves turn light green (compared to their healthy colour) or slightly yellow before falling on their own. Spots, instead, appear mostly on edges and tips, and not in the middle of the leaf like before. Perk-up remains but in lower levels. Clawing is slowly disappearing / it's barely noticeable. Feeding Today i fed her a quarter of enhancer recommended dosage (0.25g x LT) as Highlander's still recovering from the flush, but i couldn't miss this feeding as it would've fucked up my schedule too much. Soil was still a bit moist: on a scale from 1 to 4, it was 1.5. Yet, as said before, i had to feed her. So, instead of feeding her the standard 4LT, i fed her 2.5. PH spikes So, since i noticed chlorine symptoms, probably mistaken for a N deficiency/toxicity, i decided to let my water rest for as much time as i have on my hands before feeding it again. Normally, my water sits at 6.7-6.8 PH. Having left it for 36 hours in the watering can, i measured it again to see if something changed (out of curiosity). It was 7.6. A bit confused, i washed my pen a couple times. Still 7.6. I also noticed there was a thin white-ish layer of something, still trying to understand if it's limestone (most probably) or dust. Either way, removed most of it with a strap of toilet paper (no ink on it). Corrected the water to 6.5, and resumed feeding. Flowers Buds have grown exponentially in the last week. I don't know if it's her schedule, or the flush effects, but flowers have nearly doubled in size in a week. My jaw is on the floor. I've dared to touch one flower. Smell is definitely piney, with a touch of lemon or some other citrus i can't recon. Pics I guess it's time for a couple 'o pics. Highlander's canopy: Highlander's hopefully lenghty colas: Highlander's flower close-up: She's getting frosty, this early! I'll see y'all in a week or so. Peace!

Now that the issue is slowly fading away, i have more calm to make moves. I've noticed clawing is still present, both from N and overwatering, but i guess in a couple days it should be fine (except for N that is still a mistery to me). Then, today, seen a leaf falling, got it and looked at it. It wasn't yellow, nor green. It was.. rusty.. bronze. FUCK! CHLORINE! Reading Chlorine symptoms: -Leaf tips and margins burn, turn bronze color (it is happening) -Young foliage turns pale green and wilts (it is happening after flush) -Roots are stunted basically forever, but i can't verify it -yellowish and bronze leaves are smaller and develop slowly (always had small leaves, dunno if it's genetics) -Young leaves develop burned tips and margins (some leaves did it in the first 2 months) NOTE: both severe def. and excess have the same symptoms. My leaves don't turn completely yellow before falling, they turn bronze! But since the leaf is so dark, the bronze is barely noticeable. Starting from now, i'll let my water evaporate for 36 hours before using it. Haven't done it before, so i guess mine is an excess. Flushing also happened with chlorine, i guess. If it's toxic to my plant, i wonder what the fuck i'm drinking everyday. Meh. Peace!

Exactly what i was looking for. Since my cab is 60x60 and i'm a stranger in SoG method, i will probably always grow 1 plant per cycle, so 1 light is perfect. Also, 100W is so little compared to my actual 320. I'm also considering to buy a regular light, such as a Mars II Pro Epistar 80, but its spectrum is way less fuller than a cob. If you had both (FS and COB) what would you prefer using? I'm of the idea that a fuller spectrum is more beneficial to the plant than a double-band lamp.. But i might be wrong.

I've performed the flush today, as yellowing came back, even though not as hard as before. Anyway, i am tired to see it coming back, so i did it. As you said, third runoff was way lighter than the first, so i figured the media was almost clear of that. Another thing i added is washing the cloth-pot itself. Didn't know there was so much build up on the sides. This is important because cloth when wet retains a lot of water, and if that water is full of nutrients then the external roots risk burn (my guess). Anyway, plant clawed for a couple of hours (overwatering), and now she's fine. I've got a fan back down pointed at the pot, so that it dries a bit faster. I'll resume feeding next week, at half the strenght, and then back to schedule. Let's see how Highlander recovers.

Little update. Highlander's clawing is slowly disappearing. Leaves stopped yellowing and falling, it's been 24hrs since the last one. Also, the perk-up/praising the sun god stopped. The only change done to the setup is the increased rack height. Now it's early to make claims, but my hypothesis is this one: Having set the rack at 32cm, plant was getting too much light. To balance the issue, she started sucking up the nitrogen from the lower leaves to sustain the canopy. The sucked-up nitrogen went in the already nitrogen-rich upper leaves, that started to show signs of toxicity. Plant's last resort was perking up, trying to say "yo, please, sun is burning bruh". By bringing the rack back up, the N need was less and all went back to normal. Trichomes are starting to develop around and on flowers. Haven't dared touching them, smell should come along in a couple of weeks. Stretch seems to be done, at least most of it. Got quite lucky with it, as i still got 15cm left for the rack (light source to canopy distance is 41cm, can bring it to 56). If i'm ever going to do another grow in the future, i should consider buying a better led light. One light. 8 sockets are quite a fucking pain to handle. Boo me, again. Speaking of lights, has anybody here had experience with COB LEDs? I'm thinking of buying one to give a much full-er spectrum to the plant, not just blues and reds. Is COB worth the price? Any opinions about it? Peace!

Indeed, i am still deciding wether to flush or not. With the flush, i'm aiming to remove any substance still present in the allmix media, and not to remove ghsc powders as it's useless to even try. But i am also aware that flushing is putting on the plant extra stress, so if i do it, i'd better be extra-careful. All i'm reading online about that "praying" is that it's the light rack too close to canopy. I don't know if it's true or not, but i don't want to risk anything, so i moved up the rack just for safety measures. Stretch should almost be done either way. I prefer not to pluck them off. Again, it's adding just a little stress. When they fall on their own, they were ready to. At least, that's my opinion, but nothing changes the fact that some leaves are falling. Of course, with the change of light supplied (18-6 to 12-12) plant should adapt to it and think seasons might be shortening, so i guess some leaves falling are normal.

As always, my friend, it's a guessing game. Winner is who guesses right. I think i had the signs of both light stress and Nitrogen issues. Afterall, space is little, light is a lot, and i fed her a third of the dosage. If highlander fucks up, and all goes wrong, i'm the one to blame. Nah, didn't send an email to them. I'm pretty pissed on my own for them not to include the chart on the product. I mean, what do you do when you eat milk? You read milk's numbers and shit! It's normal for us! hehehehehe.. I'll see in these days how it evolves. Surely keeping a close eye, but overall there's not much i can do other than raising the lights. Thanks for the support.

I've increased the rack height to 40cm, instead of 33. From another site: "When the whole plant is being overworked, it starts showing signs of what appear to be nutrient deficiencies. At this point, it might seem like a good idea to increase the nutrients you're giving your plants. Unfortunately adding more nutrients at this point can do more harm than good, often leading to even worse nutrient burn. Because the true problem is the light being too close, upping the nutrients isn't going to help, even though it may look like the plant is suffering from nutrient deficiencies. These overworked leaves began dying early! They showed signs of both nutrient burn and nutrient deficiencies at the same time, though the true problem was the distance of the grow light. Giving the plant more nutrients at this point would only make things worse." What if my light is actually just too close, and the plant showed signs since it stretched? It's another possibility. I'll see in the coming days how it evolves. Peace

I've researched again a bit on the topic of the perk-up. One possible reason is that the plants are receiving too much light. Other reasong could be high temps (not the case) or low humidity (not the case). I'll increase more the height of the rack, bringing it to 36cm instead of 33, and see if that changes something. If it doesn't, i'll turn off a couple lights. Could be that the plant isn't receiving enough co2 from the enviroment to sustain my light. Other reasons, i don't know. Peace!

Look at them! That's a beautiful recover. Looking lovely. Well done!
