I do agree with what's below. And, if I hadn't of checked your diary I'd of probably just said pull back on the N.
But, you're using far too many products with N in them in the same time period.
Yes, leafs can turn that way. But, by having very very dark green Background I do see your plant is been given to much nutes. And N is the most uptskable nutrient across varies stages of ph. Tis why its mainly the 1st we see in an overfeed. Pull back drop 1-2 nutrients. Or break them up. Give them on separate feed. 1 half at the start, the other at the end. And the LOW EC / SALT nutes can do in with the water feeds. There's just too many PH buffers in that pot. Your plant is struggling.
