Most of these popped on Jan 14th and the two with Pink labels “BR” one that is burnt the worst popped on Jan 4th. I used Root Riot Cubes, seedling soil, 20% Happy Frog and 20% perlite. On advise of nute co I added Bio Minerals about 10 days ago and Root Powder 7 days ago, by Dakine420.
At first I had a LED Par 38 bulb but it seemed to burn the BR (Berry Ryder) and others. So I changed to CFL’s, one 28 watt and three 23 watt. The closest bulb is 12 inches away, most are 15ish.
There are 4 differ genetics going at least so some are darker and some are burnt more. I was doing 24hrs light cycle but changed to 20/4 to give them a little rest. The temps are 68 F at the lowest and 85 F at the highest, but avg around 77 F. The RH is a little low, 36-45.
I had one that damped off and stem broke and other never had real leaves, those are the only deaths. I’m truly lost, it looks like either nute burn or light burn. The only nutes are what’s in Happy Frogs, but only put small amount in. For CFL lights most say to run them a few inches away. I can’t run them at 18 inches.?. And I’m running two gentle fans also.
The only others
Thanks in advance for any suggestions!
