HI bear!!!!!!!!!! Happy to see you grace my thread! How are you!
Im doing great babe.
Glad that my bubba kush clones are finally starting to take off on rooting....Damn things seem to have a mind of their own and a will to match it....
I surely hope that you are happy I stopped by, your one of the 5 people that I come here to check up on, the only person who gets anything other than a lurk and an email later. LOL
I thought that you plants may have a calcium deff because of the leaf curling downwards in that upside down U shape...(frowning to the floor so to say)
Also rust looking spots develop starting from the bottom up and progressively eat the plants largest leaves away....
I dont really know of a home remedy for it myself...Actually Ive not heard of one period. LOL
Best I can suggest is to get a nutrient that is high in calcium that will be soluable for your aero system.
Cal-Mag or Cal-mag plus would be the best options IMO....
and I said that you would really need to worry if you were using coco strictly because coco is so infamous for being calcium/magnesium deficent.
Cal-mag is nearly a must for it unless you have hard water....
