Learning every grow :)

Germinated all March 20 - March 30 Started with an cheap LED light it quickly outgrew. Have been growing under the natural sunlight by day, and by night been sitting with my flowering plants under 600w MH bulb. Once again not expecting much from a MH bulb when vegging. So far lessons learned... The mainlining I wanted to do, I should of left the 2 growth tips at node 1 after the first split. Due to this and my plants now maturing and growing asymmetrical leave nodes, im doing 4 colas on each, but trying to stretch them a bit first like mainlining. Don't leave leaves on for long when mainlining. So much wasted time and effort. One plant shows very quick growth to the shape I want if I don't let the leaves grow past 3 inches.
