This is my first grow and things have been going smoothly until now. Just noticed the leaves are fragile like dead brown leaves but still green. They do look like there turning red/brown. Any thoughts.
I'm assuming you're not monitoring soil ph, but it appears that your girls are expressing an Fe deficit. Ph of soil appears high. Just a guess. Without more info it's difficult to proceed with diagnosis. If so, you should flush with three times the volume of water as your pots volume.
I only water with pH 6.5 water and my soil tester shows about the same. I'll just flush them like you said and see what happened. Thank you for responding.
