I decided to give the Girls one more veg week while i tried to gently adjust the ph. Although just managed to achieve a 7.5
Plants are getting bigger and I have limited space so they are going to flowering anyway.
Guess the ph was high due to dolomite lime I added when measuring with unclaibrated ph meter and got misreaded 5.5ph
I plan to add some bokashi and worm castings aiming to get to the 6.5 ph.
Girls are looking fine only some leaves yellowing thanks to the ph locking some of the nutes.
