HELP! Flowering Possible Calmag deficiency with burned tips?

[mhyg420]

Week 5 flower. Unknown strain of funky stuff.
Happy frog soil with added perlite in a 3 gallon fabric pot. 400W actual draw LED light, no ventilation yet, heat in box goes from 68 at night up to 90 at the highest during the day and the humidity spikes up to 80 at night when I close the door, bur is between 40-60 during lights on..
I cut off 2 fan leaves to show the problem starting. Would love some advice because I know how fast this can worsen. It looks like a calcium defeciency with the spots but also has burnt tips. I always ph my waterings to 6.4-6.6
Over or under-watering is definitely not the issue

Soil ph should be between 6.8-7.0. Not sure why you ph’ing at all. Really not sure why so low

Nice healthy plant. I ran across this chart and used it in my current grow and liked it.

Bright Agrotech Nutrient Deficiency Chart

I found this chart for chlorotic (yellowing) leaves and thought it might be helpful. It's for aquaponics but I think it'll be good. http://odlaiskola.se/Diagnostics.pdf

I like your lighter on the counter a burnt end. Smoking bowls much

Not really seeing much of an issue … plant looks good overall.

Remember hyperfocusing on very minute things will drive you to do bad things.

However , air exchange would be a good idea , since you stated “ no ventilation “ ….. even if simple oscillation fan.

Yeah that's pretty good advice.

Should have been specific, I do have 2 fans for ventilation, just no inline ducting, just leave the door cracked open.
Thank you so much for replying to me, I appreciate it!
