Is that ph fluctation?Low temp or light burn?

Nah, I looked through wk, 7,8&9. Bring down the bloom booster to 2ml. Increasw cal mag, plants in late flowering lv extra cal, and all the fancy sugars, but using too much causes the plant to leave some behind and really if you giving different nute. Check what's in them, a lot of the time they'll have the same nute, maybe just given in a different method. Ur PH only changed by .2, and even 6 is still fine. Slight def that's all. Possibly caused by start of nute lockout if u are mixing nutes stop for a week. Give sep. And give water in between each feed to lower salts. Nice looking ladies. Happy growing.
