About to be the 5th week. I have been adjusting the ph to 6.5. I have an electronic ph tester that I bought at a hydro store. I though it might be lack of nut, gave them some more nuts and they dont look any better. They are getting worse. Should I flush them??
Looks like a severe potasium deficeincy to me. Also other leaves look a bit N deficient in the the background, very yellow, that is why I don't think it's burn. And nute burn starts at the tips. Just my thoughts. Good luck though.
