Hey Bro,
Looking good! First I suggest maybe putting some tin foil around the pots to block any light penetration. Roots hate light. I would'nt feed them until you get at least 2 to 3 sets of true leaves, then maybe 1/4 strength. What kind of soilless mix are you using? Any of the commercial stuff is good. Most of the folks around this site tend to frown a bit when you mention anything like Miracle Grow, the simple fact is that these soils are made by the pros and most have a certification and are regularly checked by those who certify them. If you would like to know more visit
www.mandalaseeds.com under soils. I don't agree with everything they have on their site especially about feeding your plants, but by far one of the most informative sites on growing you will find. Anyhow, most potting soils contain time release nutes and will feed anywhere from 3 months to 6 months. However these amounts are so small and M.J. grows so fast that you probably should repot and start feeding after the second or third week. I go from a 4 inch pot to my large pot (two gallon) after she has enough true fan leaves and she gets root bound, about 3 weeks.
Start with these suggestions and if you need more information just post your questions. Also, the plant you see in the above post is grown under total c.f.l. start to finish, in Miracle Grow potting soil. Awesome seed genetics, a whole bunch of t.l.c. and not to mention 6 years of horticultural studies in college,all credit courses done at night. And no sgrog or l.s.t. on her either, just let her do her own thing. Big mistake! She pretty much out grew her space so I strongly recommend some sort of training. Her yield was lust under 3 ounces dried, just as the breeder said she would produce.
Get your lamps 1 to 2 Inches away from the top of the seedlings to reduce stretching, start now, if you intend on using c.f.l.s exclusively 1 to 2 inches will be par for the course . Use a fan, point it at the bottom of your lamps. MAKE SURE YOU PUT A FAN ON THEM OR YOU WILL BURN YOUR TENDER SEEDLINDS.
Good luck,
