This is my first time with Dyno too but i dont think thats the main culprit. I prepared the pots separately but similarly and the CBD stunted but then again I'm not sure what to expect. I've been told they stay small. She has been getting plain water and showing no signs of deficiency. I double fed the Blackberry and the yellowing and leaf curl got a bit worse so that's not it. I'll try and lower the pH of the water next time and give her some Epsom.
Like one of the guy here said, "we're growing flower not leaves". At this point she has enough green to make it to the finishline. It would be nice to not have to limp through for once.
