First Indoor Grow

First indoor grow, standard start, sprouted from 90%coco 10% perlite. I ammend/mix my soil with gaia greens 4-4-4 and 2-8-4 2 tbs of 4-4-4 and 1 of the 2-8-4 per gallon of medium. I use 15ml of molasses to 1 gallon of water mix ratio, in this grow I end up over watering in the first few ish weeks, It was not bad enough to cause too much damage by the look of it but I believe I definitely stunted them as a result, I have takin steps to correct this but unfortunately during my 5th week I noticed gnat larvae show up, luckily they never seem to get past the larvae stage so I must be keeping their numbers down. I never notice any in my traps so Ill take it as a good thing.
