From a fellow grower:
So my plants are 2 weeks old and they seem healthy besides that they are a little purple and 1 or 2 of the leaves are turning completely yellow. I bought 3 blueberry medical. I used some ph water to correct the soils ph. I’m using led 35w bulbs about 8 inches away from the top of my plants. My light cycle is 18-6 but I’m changing it to 24 because they seem to not be growing. All the true leaves have popped and look a normal dark green color. Please help me save my plant.
