Is that the A&Busing canna veg nutes
Lack of your PH is off and because you use Distilled you are or will be Cal Mag def. Just use tap and you will be fine. I tell you what you foliar feed one and not the other and if you do not see a difference in the two then I will kick down for the spray.so your thinking overwatering or lack of nutes?
as for being stubborn. ive grown from clones in perlite using the same nutes (crappy ones at that) for about 6 years. its only since ive become friendly with the local hydro store guys that i have caught up, if you will, with things. im using coco now, 2 part nutes and a ton of extras on the side, new methods (SOG, warehouse). but who knows i might get bored or enthusiastic one day and think fark it and foliar feed
stranger things ahve happened
Ding, ding, ding!!!Guys hes growing in coco not soil,coco has no nutes he has to add some,it looks like your ph might be a little low and maybe a cal mag defencie.The plants also looked overwatered!!!
