ahhhh very interesting cool I will keep that in mind, honestly i have no giving them any extra nutriets since i mixed the dirt for the pots, just a 1/8th teaspoon of organic fert.. the soil and the fert, are both "coast of maine" id rather not give them any more fert, if i dont have to... Id like them to be as natural tasting as possible, but if i notice a deficiency I will add a bit more.. but maybe its the water, I have never ph'd the water, or even tested the ph, because I am been giving them only 'poland spring' water and i figured it must be good because i love it hahahah, but the tips of the leaves seemed to get better when i cut down the time on the L.E.D. but im going to take your advice on the angle of the lights and see if that helps me out, thanks for the advice, anything i can pick up will help me
