lets hear more details. should be easy to figure out with coco.
coco has a few problems that pop up often.
1. crappy coco or improper rinse before use is the number 1 reason for coco grows going to crap.
2. not watering coco often enough is next on the hit list. coco isnt soil and shouldnt be treated like it. coco should be watered atleast daily but preferably multiple times a day. no need to wait untill it looks dry.
3. although coco is a great medium some nute lines seem to do better than others with coco even though they may work like a champ in other mediums. for coco i usually recomend a 3 part base nutrient a few additives i personaly use an's 3 part base, mother earth tea grow and bloom, beneficial backteria in the form of an's pirana and turantula, gro teks carbo powder to feed the bene's and for flower booster i use grotek's monster bloom. this usually keeps me from needing any sort of cal/mg supplument and things go smoothly. it sounds like alot but most of the time your just using the base and tea once you have an established population of bene's growing in your resiviour or medium just gotta feed the bene's every now and again with carbs and about wk 5 of flower start the bud booster. i like to let ph swing also when using a res i ph the res at 5.5 and drift up to 6.2 before adjusting back down. this helps keep individual nutrients from getting locked out.
