Hi guys, I am at my first grow, and my babies are showing deficiency spots an curv on the leafs edge,as you can see from pic. The third pic, is the one who started 3 days ago, then one more, and now the bigger one on pic 2, is getting yellow on one spot, and leafs are curving as well. Here the ebtire setup: In a closet 38"x20"x50"H. 8 pots with coco and perlite are about 1,7gal (planning to flower at 20" for a sog) Using GHE go box at half strengt, plus Sensi Cal Mag xtra full dose with osmotic water. (should i double up the cal mag?) Lights are two LED boards 3500k here the description link. SYSTEM250 ZEUS 308 COMPACT KIT 3500K - CC Modul Temp is 27°c Humidity about 50% 6 days now since cotyledons appeared. Someone told me it is nute burn, since it would be a pain to flush now, if i go with less nutes from the next fertigation (considering the early grow and the fact that i let runoff 10/20% everytime), would be ok? Or flush is mandatory? Please help asap to understand if is serious, thank you all!
