I moved across the country and have been living in the total boonies (and I mean out there). Raisin' the kids, have another on the way and bought a house, I've just been out of touch.
Thanks y'all, it's good to be back.
There's always a chance that mixing stuff can bow up in your face. If it hasn'tbeen showing any problems yet, it probably won't be an issue, depending on how long you've been giving it to them. I don't use either of those nutes but a tablespoon of each to a gallon seems like a lot, is that what...
Most strains mature in 2 months. It sounds like propaganda to me; "Before we could cut the plant and destroy it, but this plant will come back to life unless it's taken out by the roots."
I just don't see it.
Looks like burn to me bro. I'm no soil pro but I'd do a good flush, get the pH back to normal and watch the new growth. What nutes did you give it and how much?
My guess would be the air resistance in the tube is more than your fan is pushing/pulling. If you really want to move some air get a bigger inline fan, make or buy a reducer and really push/pull it from one end of the tube or the other.
I've never used anything like it but would probably lean towards CFLs and the likes, fine for veg but you'll probably want more for flower. Usually T10 is referring to the way the bulb plugs into the socket. T10 is a common term for one type of the two prong type flouro. sockets.
How hot it gets...
