* I prefer 20/4 to 18/6 for vegging.
* MH bulbs run HOT, monitor heat and keep the fan handy.
* TP from seedling pot to one-gallon pot is fine. Then wait until the larger leaves stretch out over the pot rim before doing another TP.
* TP from the one-gallon pot to a 3-gallon pot is all you should have to do. One gallon of pot size is judged adequate to support a plant one month. If you plan on harvesting in less than 12 weeks you won't need a pot larger than 3-gallons.
* One FIM when she is 6-8 inches should be enough.
Good luck, BigSteve.
