I was thinking sulfur because of yellow new growth. Or zinc. Idk at this point. I'm not familiar with this particular strain so the feeding schedule is def off. I am using the oLucas formula 0-8-16 micro and bloom. I am flushing them right now and they seem to look alot better. I'm gonna switch to different feeding refining. And 280 is def high. So u think I should get an r/o system? And how do u fix the boron and molybdenum def? Never had any deficiency. U recommend any certain nutes for rdwc? For some reason the ph is dropping with the Lucas formula. Or it could be the chlorine evaporating in the water I guess.
