Cheers Herk, the slight shite root problem is all sorted, no more gunk on them, theyre nice snd white and growing steadily. But everything is still mega slow. Everything is perfect, P/H and PPM wise. The only thing that I can think of now is R/H, i've struggled with this from the start, I nearly bought a Humidifier a couple of weeks ago but thought nah she'll be O‘right. I wish I had now. I'd say the average inside the tent is 30% and I can increase that a couple of times a day by spraying like fuck but its still low.
