so here is the deal
there is a lot to read on this forum and other about coco
but I will give you the rundown
coco needs to be fed everyday
coco needs to be fed the same ph everyday
coco needs a very consistant ec everyday
coco needs to be fed to runoff 10-15% every day
so here is my advice
feed per galon
3ml
CalMg+(
botanicare)
3ml grow
2ml micro
1ml bloom
keep your lights 18" above canopy
feed once a day....every day for 1 week
update this thread with a picture once a day
and we will see the progression from startpoint to end of seven days
during that time use the search function for coco growing
there are some dudes on here with great writeups on the use of coco that has great information
we will def help you along
but I advise to do as much reading as you can
another GIANT piece of advice
do not get hung up of diagnosing deficiencies
in coco if you feed correctly there wont be any to diagnose
and if you see the plant getting to light you up your feed
getting to dark you lower your feed
super simple
hope this helps
