I would definately veg those at least 2-3 more weeks. I would also get a better light. 150w is pretty weak by indoor growing standards.

Phunnyman and st8outtaweed gave good suggestions for soil. There are some great nutrient enriched (specially made for MJ growing) at your local hydro shop. Also they can help you with your nutes. They will have some simple 3-4 step recipes.

As for watering, you can add your nutrients straight into the water. Mix well before feeding. You can find amounts per gallon on the nutrient container. I usually water every 3 days....about 1/8th of a gallon per plant in 5gallon containers. Get a moisture meter (you can get them at home depot for like $7)...and just make sure they don't get too dry and definately not too much!

Good luck man! :jointsmile:
