What deficiency is this?
Purple Punch F1 Fast Flower
10 weeks old, flipped to flower 3.5 weeks ago
GH FloraNova nutes
Not sure what’s happening here. Looks to be spreading to the middle plant. Noticed it about a week and an half ago.
Any suggestions on how to fix it or thoughts as to what’s going on here?
It’s my third grow and haven’t dealt with any deficiency issues so far.

Check PH is always first in my book. Make sure your in VPD range, a good app I like to use is Dr Greenhouse VPD calculator. After verifying PH and Environment are on point then look into deficiencies. My guess is because they are in week 3 they are getting picky and either your PH or Environment is out of whack. Hope this helps.

I check my ph every time I water it and have been consistently within 5.8-6.4. Based on what I’ve read that seemed to be good. Would you recommend lowering it to mid 5’s?

I also have my humidity set at 55% and temps are hovering in the upper 60’s at night, lower 70’s in the middle of the day.

Most likely cause of mineral lockout is from an out of range pH in the media. Your bottled GH nutrients have the essential minerals required for healthy growth until the pH goes out of range and they become insoluble and unavailable to the roots.
