My grow with pics, looking for any advice

I let them grow in a cup for 2 weeks and then I transplanted 2 of them into ice cream buckets. How many weeks do you think until I need to start adding nutrients? I am using roots organic soil. I was thinking around 2 weeks until I should add nutrients. There is still 1 seedling growing in the cup.

They are under 2x(23 Watt 6500k CFL) and 1 fluorescent tube around 4150k. I have 40 watt cfls that are 2700k and 65 watt cfls that are also 2700k but I wanted to save those until the plants got a little bigger or are in flowering stage. I move them into direct sunlight every time the sun comes out also.

Any advice is great!

get some panda film and build a light trap

your losing a lot of that light cfl`s need reflectors to make the most of them outside of a mylar box/tent

maybe when they get big they can go outside or something

you need around 50/100w of cfl per plant to get something worth any hassle, some people bring in ok yields with cfls there good for stealth vegging when you need to buy everything from a £1 shop like on holiday in spain, when after 2 to 6 weeks your chucking them outside

but if its growing weed its all fun

If you're looking for a cheap way to get some reflection, white bristol/poster board all around and underneath your plants. Tough at flower but easy at veg if they don't get too big.

It will probably be a month or more until you see nutrient deficiencies.
Check out spacebuckets.com, you'll find some good ideas for small CFL grows

Hey mate you might want to get them in pots or else wrap them up real good with black duct tape otherwise the light will kill the roots
