hi, yeah there's about 40% soil in there. The drip also isn't running full time, just twice a day for 15 minutes. Supposed to be 2L/h drip, so they get 2 x 0.5L /day. I guess it isn't a "real" hydro setup... I measured the pH of my reservoir earlier on, and that was 6.5+. So that was not good. I lowered it to ~5.5, just about limit for soil, and also limit for hydro. EC values were a little high, I use tap water run through a Britta filter, btw. Original tap pH is ~7.5, after the filter it's 7.0. I follow manuf. recomm. but with the usual dilution, BUT: there simply are no specifications or guidelines for mixtures of soil and cocos. And frankly, now I'm wondering myself why did I add soil alltogether? Could have just stuck to cocos. Or hell, mapito. Because I think that now I've got all the hassle of the hydro and will have euh none of the yield advantages lol Also, I don't know whether it's better to feed them for example 4 times a day for 5 mins, or 2 times for 10, or 8 for ... etc. Most hydro setups use freerunning drippers that are on 24/7 (like clay pebbles). But soil+coco -->> drowned plants Sigh. Let's try to determine a correct-ish pH first. Also, the older leafs are deep green, all newer growth is very light green. Weird. Another thing, or possibly related. We'll see... Thanks btw!

wow, amazing, thanks so much. That pic is exactly how my plants are looking/starting to look. I was growing in pots (airpots), watering manually. After nutrients were added, I adjusted pH of the solution to 6.5. I have never measured the run-off... Medium was 40% dirt(soil), 40% cocos, and the remained perlite and vermiculite (assembled myself). Nutrients Canna Terra Vega and Terra Flores, at half manufacturing strength. So I only measured the pH of the solution right before I fed it to my plants, so accounted for tap water and nutrient pH changes. But never tested runoff. This new batch were vegged in pots, same method as above (hence, same results I guess). One week ago they were put in a hydro system (Wilma 4 pot dripper system, recirculating setup). I kept my feeding schedule roughly the same, ie I made the solution as I would have in the past, and filled the hydro reservoir with that. Just measured the run-off there, and that was 5.8-6. So, I guess the solution would be to lower the pH of my reservoir solution? The medium now is the about the same, 50% cocos, 30% soil, perlite, vermiculite, in well-draining pots. What pH do you recommend? 5.5? Or even lower? Run-off is now ~5.8-6.0. Should I change the nutrients as well? I figured that my setup now isn't really a "real" hydro setup, just a drip (I hardly get any runoff). Thanks so so much!!

Hello guys and girls, a new grow, and the same disease... I really don't know what to do anymore. It starts with leafs looking like this, and then slowly dying: Please, if anybody has got any clue... Love, Peebz

yah, all plants affected some more pix: Does anyone know what this is, and how to solve it? At a total loss here...

yup, seems the new grow is affected as well. Damn, not even into flowering yet I'm at a loss here... growing in soil, moisture OK, pH OK, nutes at 2/3 recommendations

Hello guys/girls, during my last grow I noticed some kind of disease. It started in early flowering, with little spots/patches with a silvery shine appearing on one or two leaves. Then it gradually spreads to all other plants and leafs, resulting in almost all leafs having white, silvery spots. Eventueally it slowly progresses until each leaf has turned completely yellow. The moment I noticed I was having "issues", I stripped my plants of the "infected" leaves, leaving almost no leaves whatsoever. Despite that, the grow finished this weekend, I'll put em in the dark today or tomorrow for a day or two and then cut em. Originally, I thought it were spider mites; however, I never saw any "webbing", and could not find any creature or bug whatsoever, also not on the underside of the leafs. No bugs in sight. Started a new grow, and now I'm seeing the same on my growing (week 4) plants. Pics below. If anybody recognizes this supposed disease or nutrition problem, please... you would be a life-saver... So thanks in advance. BTW: I can't seem to post pictures next to one another, so horizontally. Now everything is vertical, sorry bout that, hate it as well
