50w/sq ft with hps.. so if you are covering a smaller area than 12sq ft probably need more height if it is already sufficiently covering entire area -- i.e. good growth on edges and corners. if not, more reason to added height from canopy. I'm guessing that 600w puts out about 1000 umol/s ... use that relative to size of garden and reference a dli table. shoot for 35-40 DLI .. either through power dimming or increased distance from canopy - the latter is more wasteful with electricity, but better penetration and more even coverage on outskirts.

Burn from hids, aka raise light ( could be ) plus they streched, hight temps most likely too, i bet on this Nitrogen toxicity ( meh, but bottoms very dark ) Wind damage, but would not hit far and around all plant Just started to drink more and you late with watering

Living soil and rain water problem Has using rain water killed my living soil? Has anyone got experience of using living soil with rain water? Apparently the ppm is too low (just like RO water) for the plant to take in nutrients. So basically is my living soil now just soil or is the microbial life still there?

So I noticed on day 6 she started to stretch, she was the leggiest out of all 4. I swapped out the cup as it had a surround on it for jug to improve light. I think this has helped. BUT her cotyledons are very dark green and curling down and under, and her top is smaller+darker??

Damaged leaves The first two images are both the same strain with similar problems. The leaves are not developing to their full length, almost like they are cut in half. Also the smaller leaves are curling downwards and are completely stiff, almost crispy. Any idea what that might be?

Yellowing, wilting, stunted growth Can anyone please help me identify whats wrong with them. I've done a flush, adjusted the lights, reduced the nutrient strength, I've pretty much done everything and still stunted growth and they are still looking weak and frail. I'm lost and I don't even know what's wrong.
