Komar85answered grow question 3 years ago What kind of soil are u using ? All Mix is preloaded with nutes for 3-4 weeks so u dont need feeding u plant . Lamp should be around 18-21 inch from canopy . Start 25% seedling 50 % veg start flower 75% for all stretch and from week 4,5 100% if u start from 100% with strong led u just burn u plant from excesive Light source and if u use 100 % from beginning around week 5-6 u will need another lamp because u plant will need more intense Light to fatten buds.
I hope that was helpful
Happy growing
