Thank you! Does this chart still apply the same to coco as opposed to soil?Looks like a deficiency triggered by low pH to me, now beginning to struggle getting calcium. Below 6.0 the plant can't eat calcium, magnesium, and a couple other things it has marginal uptake in pH lower than 6. I've included a chart to show the sweet pH range for cannabis.

5.9 ph is fine in coco. That shouldn’t be your issue. I feed lower ph than 5.9 in coco all the time and see no issues. Where mine lands between 5.5 and 6.3 I send it and have never ran into a problemHoping someone can help me diagnose what is happening to my plant. Grown in 70% coco 30% perlite (Tupur) and fed Cronk Nutrients full line. Ph has been consistently 5.9 and EC at 1.5-1.7. Any advice would be greatly appreciated! Thank you!

FYI - OP is in coco, not soil although I do agree that his EC is high enough to fry the plants ... if indeed the reading is correct.Oh man I just saw your EC, thats bad, thats more than triple what they should be getting. Is that the EC of your water with nutes or in the soil? In whichever case is bad.
Yes I know, still too high like you said. If that was the EC in an organic soil I wouldnt be worried but being coco is way too high at that stage.FYI - OP is in coco, not soil although I do agree that his EC is high enough to fry the plants ... if indeed the reading is correct.

I'd be more inclined to call it magnesium lock-out. I bet there's plenty in the soil but its uptake is being prohibited by all the calcium being sucked up by the coco.If I had to guess Id say thats magnessium deficiency. I dont see burnt tips on the leaves and with such high EC is rare so Im pretty sure is a lockout.
Oh shit and before I forget, keep in mind that if you flush you will probably have to buffer some extra calcium that will just bind with the coco and stay there. If youre using tap water then no worries but if youre using RO perhaps put some extra calmag after the flush only once and keep the other things lower then keep using calmag as usual without surpasing the showed EC with the overall dosages.
