Hello all, me and my mom are growing 2 plants and we are having some issues with tip burn.
I know tip burn is caused by to much nutrients, but I've only feed them low dosages and I flushed.
My tent (panda and pvc) measures, 7.7' high, 4.6' wide and 3.8' out from the wall.
I'm running a Atreum VELA 320W led grow light.
I'm growing in 3 gallon root pouches.
The medium I'm using is, Pro-Mix Premium Moisture Potting Mix, I mix with crushed red lava rocks.
I'm feeding with dyna-gro fp w/ protekt.
Growing 2 plants, Bag of oranges and Chocolate deisel.
I was having a condensation problem, so I had to get a sheet of 2" thick r-10 insulation to put under the tent and that fixed the problem.
I make sure the water is kept @ room temp now (Luke warm to the touch).
I started feeding at 2.5 weeks in, first time I mixed a smidgen in a gallon and feed, after that gallon was used up, I mixed a dash in a gallon and my problems started. I started getting tip burn, it burned a good 1" to maybe an 1 1/2" from the tip up, so I cut at least 12 leaves off the orange and the chocolate didn't burn so bad, just very little tip burn.
I was thinking that it was the cold water and floor that made the roots cold and shocked the plant leading to a build up of nutrients, so I flushed and feed after the pots dried out and I started getting tip burn again, but not as bad.
Now I'm thinking this soil may have slow release nutrients in it, so I called pro-mix and the women just read the web site to me...
Now I'm just watering, I haven't feed in weeks and now I'm in flower and they are both flowering.
Does anyone know about or have any experience with this type of pro-mix soil?
Edit; I didn't water till runoff at first, but I've been watering till runoff for over a month now...
Edit Again; 12/12 cycle for about 2 weeks and budding for a little over a week.![20211208_084036.jpg](/data/attachments/4144/4144986-91c7306c97664533b9b4be4348e78e23.jpg)
