I have 4 plants. Upper left is northern lights Auto-flower. The other 3 are blueberry cookies. The northern lights plant is the only one that has twisted leaves. All fed from the same tank using auto pots. I had scooped up some water from the tank about a week ago and drenched the plant. No change since then. thank you b85487e30c2bd9bea268cce90e9c0c22.jpg[/IMG] Sent from my iPhone using Grasscity Forum
I also see some Calcium deficiency (drawstring on tips of some leaves) and some over-watering (speed bumps and chicken claws). What are the room temps?
I have been adding cal/mag for a couple weeks now. The leaves were getting yellow as you can see in the picture below. Since adding they seem to be coming around. Here’s my mix as per advanced nutrients. See pictures. I am using all of the nutrients listed except for Tarantula. I have just started wk 2. I also add in 15ml of Magical by Technaflora for mg/cal. I start with 8l of RO water add the nutrients. The TDS is about 1675 ppm. I add water until the PPM reaches ~950 then feed. Lights on ~25-27 deg C ~45% Rh Lights off ~20 -22 deg C ~50-54% Rh Sent from my iPhone using Grasscity Forum
Tough call. If it's not heat stress, it could be Mag deficiency, but you're adding plenty of Mag already with the nutes from A.N. Plus, the slight bending at the edges isn't all that bad. Do you water them enough?
