Peanut Butter BreathxBlack Cherry PieF5

My first time running coco coir. 7 Days after Flip. Plants looking pretty bad from what I'm hoping was previous nutrient deficiencies. So far I'm having trouble getting my dry backs down. To me the coco coir always looks wet. I think I've been watering to much(.25 gal per plant) and now will try to give the plants around 330ml(1/12 of a gal) of feed water per watering. Was getting getting 50% runoff. Should have reduced volume of water sooner but concerned about coco drying out and plants dying on me. Most days I water twice. I want to get them sexed and then set up a automated watering system and increase the frequency of watering. I've been looking at Growteks auto water system but they are out of stock as of now. The node spacing is also not the best but perhaps that's my bad. Also planning on taking clones at the end of week 2 or 3 of flower. The larger plants are Rockbud genetics that have been in 24 hour light cycle veg for over 60 days. Thanks for looking.
