should i feed it? and how do you flush these 6 inch blocks if needed?its hard to tell with the yellowing from the hps light glare.. but im sure thats what it it being your only this far intothe grow..
got one. and also why plant 1 when you can plant 15. I am Humboldt County outdoor guy. 15 is not that many plants. LOL. This is my first indoor setup. I bought this setup to play with. I am not buggin over 15 measly plants, if they die i plant more and try again. I am just trying to figure this shit out. And I did figure it out. Nitrogen deficiency. I fed them Humboldt nutrients 25 ml. Micro, 25 ml. Grow, 25 ml. Bloom in the 40 gallon reservoir and BAMM! all 15 bitches bounced back. and i figured this out on my own. I figured it had to be some sort of deficiency due to the fact that all it was getting was water with no nutes. how the hell is it supposed to live. In soil seedlings get nutrients naturally thats why you dont have to give them nutes in the beginning. make since. I was reading people say no nutes in the begging in hydro, and i found that to be completely untrue.get a ph meter dude.. keep it neutral and u wont be buggin out over tiny ass seedlings.. if that was me i would of researched a whole lot more before planting 15 plants.. peace and good luck
