For veg I use MaxiCrop Liquid fish N Kelp. For Flower Medinedas Hasta Grow N Kelp. Half way threw flower I add Sea Bird Guano. I use FF HF soil mixed with equal parts Kelloggs patio soil and a couple of shovels of clay pebbles.
I would back the light off a bit. It may be to close. I have 3 Skunk #1s under T-5s at 24in and they are reaching for the light. I think the LEDs may be a little too strong.
Walmart bags work Great, they are cheap. I like to veg mine in 2-3 gal pots then add a couple of gal of soil to get them through flower.Just roll the lip down a few times and you wont use so much soil
usually when my leaves curl on the edges the temp is a bit to high. i like to keep my room about 73 lights on. at night it drops to about 68. Humidity about 55. Good luck with your grow.
when i grow soil I usually go from Dixi cup to 5 gal buckets. Just drill a bunch of holes in them for air,& drainage. If you want to keep them short, topping , Fiming, Etc all works wonders.
The roots out of the water will be a little darker than the ones in. If you are running Cal-Mag they will be alot darker.I would suggest getting some Kanga Roots. Keeps the roots healthy n happy. As long as there is no slime you will be good.
I have placed 2 orders with TNSB and have received both with no complaints. I believe if you pay the extra for stealth you have no worries. Ive actually received beans before i got my tracking #.
