Anyone ever seen this before? Dorm grow 900 W LEDs. Veg out beautifully. Flip them into flower, pistils come out turn brown die and curl up. Leaves curl. Growth is stunted. Buds turn hard. Our main suspect is they've been stretching fast and we haven't been keeping up with raising the lights fast enough. But we're also sure they haven't been getting inside 26 in. from the canopy, which is the min. recommended distance from dormgrow. We have some beauties almost done flowering who are about 32 in. from the lights, and they grew under the same system. We've had others that have gone through this already, some have recovered and pushed out fresh white hairs (after weeks of recovering), others not so much. Its been agonizing. Any input is appreciated, we've never seen anything like it. Here's a good side shot you can see how the hairs are curling and brown, week 4 today for this bud. https://instagram.com/p/zjguCxFWvR/?modal=true Better shots outside of the LED These should be coming on week 7 of flowering... https://instagram.com/p/zj5Sf3lWl5/?modal=true https://instagram.com/p/zj5MFAlWlx/?modal=true
looks similar to heat exhaustion ..keep 2 minimum temp gauges in there, maintain 25C/77F also a small fan to circulate the air ...and YES weed breaths too, safe distance is ..place your inner wrist at the intended hight for 3-4 minutes no pain or smoke then you plant Could be safe ..stay sharp check your temps often
