Hey all, I am growing 8 seedlings of church and arjanz haze #2. 13 days old and were stressed at first from stretching and pH imbalance but on a good track now in deep water culture. How do i know when a small little plant is considered to be in vegetative state vs. seedling stage so I can raise the nutrient level or start doing a 24 hour timer as well... first grow so do not know
