Deficiency problem

[Supremegod]

Hi I am a beginner grower just started growing indoors. I currently don’t have a grow tent at the moment so I just use a lil enclosure to grow them under my desk. I’m using a 120w grow light bulb I have one fan blowing and I covered the surrounding area with aluminum foil I plan on moving them to the closet. I’ve been using the Mother Earth all purpose soil and I have the nutrients root booster, liquicraft grow and floressence bloom. I’ve added a small dosage of the compost I’ve made from the three. I have also made sure the ph was correct for the compost as well. The plant just started week 3 and I’m seeing major yellowing starting from the bottom making its way up someone told me it could be a nitrogen deficiency but I wasn’t sure I need help fixing this before it gets worse.

Without pictures it's hard to tell. Could be overwatering, could be nitrogen deficiency, could be rootbound, or it could be not getting enough light, 120 watts is not much, especially if it's an incandescent light.

Saw your plant pic in other post…. it cannabilized them, meaning the plant sucked the life out of those leaves leaves….

whatcha growing autoflower, photoperiod or just a bag seed you found??
