List of details:
One NYC, one Cheese, both autos.
Day 29, look to be in pre flower.
Indoor, vivosun 2x4x5 tent with spider farmer sf2000.
tried to keep distance plant/light at 18” but there were a few days where it was as little as 12-14” at 80% intensity.
Happy frog plus 25% perlite, 5 gal vivosun fabric pots.
No pests.
Low of 70 degrees F, high at 85 deg.
40% to 60% humidity.
No pests.
Fox farm nutes last two feeds (I feed low and at every watering, which is approximately every 5th day):
big bloom 7.5 ml, 1/4 dose
boomerang 4ml, 4/5 dose
growbig 4ml, 2/5 dose
1 ml calmag…1/2 dose?
Last feed was ppm going into pots was approximately 600. Runoff for NYC was 2888 ppm, Cheese runoff was 2134 ppm.
For last week, new growth leaf tips have been light yellow. Leaves seem quite dark bordering those yellow tips. Newest leaves are tilted upward on the nyc. I’ll include a pic below. It’s not dramatic, but I’m worried it’s going to become something bad.
After all the normal scouring of the internet, reading multiple sites, watching vids, etc., here we’re the possibilities from my novice perspective:
Nutrient burn?
light/heat stress?
copper deficiency ?
boron deficiency?
Other?
