so after dialing in the nutrients I believe we are back on track and they are growing fast! I feed the factory recommendations on the bottle, after trying to feed less it just wasnt working and the plants were starving. also i replaced the lights above the two small plants and they are starting to grow like they should. im going to grow these plants for 3 more weeks now if this was the first week. before the PPM was 600 now we are up to 1200-1400 depending on how much the plants drink.
