Yello everyone. Let me introduce a test plant number 5th or 6th. Little blur image sorry. One I know crossed JH wit NL and also maybe E. Girl but not sure and cant say for sure how long ago he\she made these seeds. Okay, this is fifth or sixth time I grow this and every time I put this under 250W HPS always the same as you can see red stems and yellow leaves which start to go slowly yellowish after about a week under HPS and finally leaves dry and die. Ive vegged this strain before under CFLs and sunlight and had no problem what so ever until I start to flower using HPS. This one is from seed and been strugglin under HPS now about a month. Its in new soil I use pretty much for all plants
(N) 100 mg/l (P) 60 mg/l (K) 400 mg/l. Using only plain water wit this one.I cant believe the problem is in the soil. Like I said seems that HPS lamp triggers this, if Id put it on windowsill it'll be fine after a little while. Temp and such are pretty much ok temp little high 27-28C. Adding little nutrients doesnt work, tried before. One man\woman have SOG using these same seeds and they look fine, little stretched and smaller buds cause he\she got 250HPS bolted on wall high and distance from plant tops is about 1,3 meters (yea I know its too far away]. I have with this plant here 50cm. Only thing that comes my mind after all the different techniques ive used (but never raised lamp more than 70-80cm) is that maybe the seeds have gone bad, are bad, somehow cant take the intense light and starts to die when moved or grown under 250W. I really dont have a clue how old these seeds are so can old or bad seeds behave and look like this?? Any good ideas are welcome and propably tested in near future. Yep thanks.

you could balance the temp  drops by using an oil heater so on at lights off on timer
