Phantom Cookie Domina "ORGANIC"

...One change I made in the tent this week was to change over my seedlings fluorescent light and replaced it with a 100w full spectrum COB. DAY 17 she has made a turn around and leaves are praying now. Only watering now when the soil feels dry. My main aim is to keep the soil moist to keep the microbial life happy. This week she will have an alfalfa seed sorted tea mixed with some aloes. DAY18 .. Saw some fungus gnats, about 3 or 5 adults when i rubbed the surface of the soil. I put some peppermint oil around the rim of the pot and some got on a leaf which cause a brown burn spot. Day 19... Added some yellow stickies to catch the gnats. Day 20.. Watered with reverse osmosis water to a pH of 6.5 DAY 21... Not impressed by what I am seeing here. There is some sort of deficiency occurring. The lower leaves are turning yellow which could mean low nitrogen but there are brown spots on the leaves the tips... I will do a transplant now as it has been 21 days and the minerals in the soil may be depleted.
