Basement Blueberry

So the first week of autos was a roller coaster. After 24hrs soaking in water 3 had popped so I planted to coco and I normally have 100% germination. Which I did. 1 more came up on day 2, on day 3 instead of giving it more time I went "digging" around and broke the radical root on pheno 5. So week 1 down to 4 phenos of the blueberry auto with a Grow lesson learned. But I am happy with the progress so far as this is my first grow in a tent and with the autos. The rh started high 60s and was slowly dropped over the week to 50 to 55%. The temp has been 64-73 thru the week. The spyder farmer sf7000 was at 24in at 20% power for the first week. That has been raised to 30in and 30% power for week 2. I only have 1 mini blizzard on the floor running for circulation and the ac infinity running on 6. I am also lower the max level on the fan to 4 to try and raise the temps to stay in low 70s. I am running a huey in the tent so I adjusted that down as well to try and maintain the 50 to 55 rh. Out of the 4 remaining phenos 1 is a bit bigger then the others. Labeled P1 this 1 started to show a tiny bit tip burn on the 1st leaves. I moved it away from the fan as it was the closest, to make sure it was wind related. I am thinking nitrogen burn possibly maybe the 1/2 casting in each 3 gallon was to much. The remaining phenos do not show any issues. I will be keeping an eye on that in to week 2.
