Super iced grapefruit cuttings 2

Day 31. Ph still climbing fast daily. Can only guess it from a lot of nuts being used altering the pH balance. Ec has dropped slightly 0.1 over night. All growth looks lush and healthy. Still tucking new growth under and moving big shade leafs daily. Noticed wen adding canna aqua vega to the tank the pH is dropping. All most as if the pH down is being locked up till the feed is some how unlocking it. Never had ph drop like that from adding feed before. Day 32, 4days 12/12 Increased the EC slightly and it seams to of slowed the raising PH. She's spreading out lovely under the net. Definitely perfect the strain for scrog.
