Are they under the same light you had them under before you transplanted them? I get that sometimes when I put my plants from veg (under 400mh) to flower (1000hps) cause the light is more intense it'll bleach the leaves.
thanks a bunch for the responds, I dont think its light burn since there are fan leafs at the tops of the plants with no issues the bigest plant is more than 12 inchs away also , and at the bottom leafs they are showing it also, here are some pics of my setup to give your a better idea
I still say it's a magnesium uptake issue. Try giving one of them a foliar feed of Epsom salt @ 1tsp/gallon, see what happens. Won't fix what's already necrotic, but it should stop the spread IF it is indeed a magnesium issue.
I will go ahead and try adding some epson to the mix, I also noticed my ph is in the 7.5 range (via two prong soil probe)My water I have been feeding them is 6.0-6.5 ish, Any way to get the soil PH in the correct range besides feeding it water>?
I wouldn't trust any "information" gained by those things. Just make sure the feed/water is in range. I'd do the Epsoms via foliar, but I like foliars.
