1st grow Misty gorilla auto

One on the left has turned a bit strange not sure what’s happened this one was looking the best at fort while the other two are looking very well too , have got round to starting the og bubble gum diary. I used the green house bio enhancer in the water to give them a boost I’m also planning on making some organic teas at some point maybe for flowering. Around day 20 I started to tilt each 3 of the Misty gorilla to start to lst and in my opinion they have all reacted well to it . One on left must be a mutant or some disease I’m unsure , if anyone could shed some light on this that would be great. What does everyone recommend the best ph for coco and green house feed bio line . All new to me but I’m learning a lot.
