-Symptoms of the problem: Okay so Ive noticed the leaves really start to stretch out and get really thin with slight yellowing on newest growth. mostly up top and its happening on some worse than others. I know sativa leaves will thin and stretch out but only the upper areas of the plants are showing this. -Age of the plant: i started a batch of autos on March 7th so they are just past 50days They started budding within the last 7 -10 days but some are a little behind others. 4 SuperCritical Auto, 1 Critical Jack Auto and 1 Auto Sweet Mango. the Mango isnt taking it as badly, shes doing a little better than the others. -Meduim: CoCo with lava growstones (Roughly 3/2 mixure) -Size of the pots: 5 Gal smartpot -Temperature Day/night: Daytime its usually 73 - 77 but the past few days have but 80-85 but this showed up before that heat spike. Night time temps drop slightly. -Humidity levels: 30 - 50% -Type of feeding (brand etc..): Soul Synthetics it was my first time using so i started off pretty diluted and i dont think they liked it. i think every plant showed a sulfur deficiency so i did quite a few waterings with epsom salts, it took 2 to 3 weeks to get rid of i think it stunted their growth a lot and the reason for some being so far behind. So now Ive jumped up to just about full strength now and theyre doing okay, except for this stringy leaves... -Watering frequency (quantity and how often): RO water. Daily 1/3 to 1/2 a gallon for each plant. feed/water/feed/water. and GH calimagic every watering 2ml/g. Ive been giving them more and more water as they get bigger. -Last EC's used: Im not sure about ec. PPMs have been around 850. sometimes going up to 1000 or 1200 once. but no leaf tip burn... -PH: I pH every watering to 5.8 -Light Power: 600 Watt was MH now on HPS for 7-10 days now -Distance from the plant: varies -Size of the room: 4x8 Grow tent -Ventilation system: 6"vortex and 12" oscilating fan Thanks guys!
