NeverEnough: During veg, I used one 24W CFL per plant. Each bulb is rated as 1560 lumens at 6500K. To get 3000 lumens/sq. ft, I calculated the distance to be about 2.5". Every forum I found had recommended to use about 30,000 lumens/sq. meter (which is 3000 lumens/sq. ft).

I used one 26W CFL per plant in flowering. Each bulb is rated at 1650 lumens at 5000K. So that also calculates to about 2.5" distance to get 3000 lumens/sq. ft. When the plants got tall enough, I used 2 bulbs/plant, giving them 6000 lumens/sq. ft.

But you say it should be 6000 lumens all the way? That is much more than others have recommended. Can you point me to a source on this?

headshake: The reason they look like they are bending towards the light source is because I used LST.

Rusty Trichome: Yes, I am very limited in what I can get. I am in Panama. I can't find Perlite, limestone, Fox Farms, or anything like that. The stores carry only MG stuff (soil, nutes). But I'll do some research to try to find amendments to make better potted soil.

But I really suspect that my problem was not repotting to a larger pot soon enough. The 1st plant I repotted 2 weeks ago came back to life. The other one died because I repotted it way too late (1 week ago).
