Cant tell if im overnuteing or if this is potassium defiency what do you guys think its on old growth new growth just has slight yellow tips
Yellow tips after feeding with nutes is most likely burn, if yellow tips and havnt feed in a while id guess a deficiency.
lol, see what he means? In my case, the clones had yellow tips, and I couldn't get any info on the recent nutrient history (not buying from them again.) I feel ya!
But im not growing in soil. Im using RDWC. and i have been using the same feeding schedule its just as time goes on thats what happens to the leaves
I dont know squat about RDWC , but maybe other people that have used it have had the same problem as you. by that I mean you could probably find a answer by searching faster than waiting.
the leaves seem a bit too dark (green), imo. are any leaves so dark they look purple? if so, you might wanna reduce the nitrogen.
