I did. Ive applied a solution and it hasnt worked. Looking for other feedback. I let my PH rise to over 5.8 (the PH at which Mag starts to be absorbed) and Ive added cal-mag 1.5 tbsp per gallon.

Its developing on the new leafs too tho. Sooo... Cant be burn. I under-feed if anything. Nute burn looks completely different.

If you are sure it isn't overfeeding ... your nutes and plants don't like each other. It's likely to be some sort of lockout (too much something is blocking N or Zn or Mg or ...) Use a different firm's product? cn

Even though you stated your ph, it does indeed look like a low ph issue. If your using a digital ph meter I would suggest you calibrate it. You have any pics of your roots?

whenever i get a plant deficiency or nute problem, i flush them. i recommend u flushing them... 1.2 EC seems fine, but is that with RO water or regular water?

Hey man your not getting any help and Idk what going on either and I'm not thoughtless enough to make a guess. You should start pm--- actually, I know the perfect person you should ask.
His sn is 'collective gardener' and him and a lot of really smart hydro growers hang out in his thread. Send him a PM or ask nicely, and post you pics in his thread and I'm positive he'll be able to help you. Also you could try 'mellokitty'. She hangs out in the same thread and I'll give you her info too.
