even number leaves are normal...thats just the way pot grows...

an oscilatting fan is a great thing to have, but you want a dedicated fan for the plants and the canopy top as well.

your plant prolly leans over cuz it is being blown over....you want a light fan just enuffto keep the air moving across..... aim the fan soit barely clips the top canopy of the plants....this will cause less direct stress on stem, but enuff to strengthen it...rotate your plants a couple of times a day so they get flow from all sides.

ok i gotta take a break now.
