Newbie central...a little humor is definitely needed here , most ""experienced"" growers shit on the new guy or 20 comments latter his/her question is still not answered
Even most pros don't use just coco / perlite it's a disaster before you even started . Way too unforgiving . I would switch it to 12/12 right away and try a good soil/ pearlite / peat/ worm castings/ ect..ect.. blend next time
