We are moving into cruise control now i grow in coco and use it hydroponically as i never ever let it dry out after roots establish themselves. This is important as its not true about not being able to over water coco you can and will drown plants if you don't establish the root system before feeding like i do.
I feed twice daily by hand once at lights on till 20% run off then again 3 hours before lights off i give them a top off till i notice any run off starting then they soak that shit up till the next day.
By never allowing the medium to dry out i accomplish a couple of things. Coco holds oxygen well and by giving it an extra feeding daily im flooding the root zone with plenty of it. I also purge out older feedings that can swing your ph or cause your nutrients to build up in the meduim.
I feed with megacrop its pretty easy stuff to grow with one part dry nutrient from seed to chop and a half teaspoon of epsom salts out of habit cause the old formulation of megacrop didn't have enough calcium or magnesium and im paranoid to get a mag deficiency.
Currently feeding 6 grams per gallon of water which is on the high end for their feeding schedule but im trying to push them a bit and will back off if i get some tip burn or show signs of any lock outs.
For lighting im running an HLG 260 watt kit and a couple 144.2 panels from atreum lighting to even out the 3x3 area i grow in with about 380-390 watts total for the space im in.
I also run them both with 4000k because i just like how they keep everything short and stocky i have the headroom for taller plants i just find it easy to manage them this way as my tallest plant atm is 2 feet from the top of the medium.
Anyways these are my ladies in the front we have 2 Kushberry plants in the middle and back left are green gelatos and in the back right is some mutant amnesia blueberry headband cross.
