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?

Ph going in was 6.4…forgot that part
Thanks for the reply!
First, the runoff ph is a touch above 6.3, and readings were done with the generic yellow pen as well as with an Apera ph20.
Second, I want to thank you for your guidance. Your videos on the yt channel inspired me to get started last year and this is my 5th grow. It even kept me occupied during Covid lockdown 😂
Potential nutrient burn, but since it's the top growth only, may be starting signs of light burn. You have pretty high runoff PPM there so I'd give water only the next few times the medium dries out. I'd also increase the light distance a little - although you mentioned you already did that. What is the pH of the runoff?
Another pic, this one of the NYC diesel. I realize it’s not a dramatic issue yet, but they’re autos and the clock is ticking. In the meantime, I’ve raised the light up and dimmed to 80 on the off chance it’s related.
