First time with hydro and do not think it could be going much worse. I got four clones about 1 month ago and they were aobut 1 ft high (cotton candy). Also around the same time started some seeds nl#1 and sour d. The clones since i got them have been going down pretty consistantly with all new growth yellow and browning bad. Also the seeds have not grown at all in the last couple weeks. Needless to say I need help, if too late for this crop need to figure out for next. Here are some specifics

1000watt mhl about 3ft away.
euro farm 8 pack with hdyroton
feed bc product to recommended strengths 30min every 1 hour
ph checked and always around 6-6.5
two small fans with fresh air comming in from next door room
temps about 70-75

Started doing some research and figured it was iron def and just fed them today both hydro and on the leaves.

I know they look like shit and don't have too much hopes of survival but what do you guys think is the problem.

looks like heat stress or even a touch of nute burn. do you always spray on the leaves?

No I don't think it is heat stress just bought a new termometer and is always under 80. Also, I do not spray the foliage very much at all, just did it recently to get some Iron into them and do it maybe once a week with a little nitrozyme. I have also flushed them about 1 week ago with straight water for 2 days and have been following the nute directions from BC. Been trying to trouble shoot this problem for over a month cannot figure out.:wall:

Just been reading some stuff could some of the problems be due to too much wind from two fans blowing directly on the plants- like a wind burn

flush it and give them less nutes

I just flushed them with straight water last Sat, Sun, and Monday morning. Did not seem to do anything but make new growth more yellow. Monday added the bc base of 15ml per gallon and bc grow of 7,5 ml per gallon. Added a little cal-mag as well. Could this be anything else or should I just flush again and reduce what is recommended on the little grow chart from BC?

dnt worry bout yellow growth for the min, at least your getting some but those leaves are burnt to a crisp. its either nute burn or as you poss thought wind burn can also have this effect but i would keep flushing with water
