I was thinking that they looked pretty tight, I've raised it a few times already. Again won't hurt. Probably another week or two and I'll flip em to flower and put the HID on em.
I'll get right down to the pictures, if you have comments or questions about what i've done feel free...the most recent pictures are from today, day 23
I used them, it depends on how long you veg for. They worked pretty well and I didn't have to add anything until my leaves started turning yellow cause the tab ran out/dissolved completely before I was done with my veg period.
So apparently my link is wrong...sorry

hopefully that works if you are interested
