Hey guys,
Has anyone seen this before? I can't exactly pinpoint the cause. They are about 2 weeks into flower and only one of the 3 Black cherry cheesecake cookies show this. Tried some recharge in the soil maybe thinking it was a lockout of some short, did not cure.

Soil: Michigan M3
Nutrients: light feed of Gaia green every 3 weeks
Temp: daytime 81f, nighttime 63f
Humidity: 60%
Light: Gavita 1700E about 2 ft above plants
Co2: 1200 ppm
Water: RO with 1.1 ml of Calmag per liter.

Any suggestions greatly appreciated!

Purple petioles usually means magnesium deficiency. Epsom salt is magnesium and sulphur.

plants like an up in calmag usually third/forth week of flowering,
than usually in up in P&K after.
so don’t go adding more calmag, you can up your potassium to help with her taking up magnesium..
