manganese def, magnesium def or end of harvest fade?

Whats up Fellow Gro'rs!

So i'm getting near harvest on my sweet seeds unknown auto flowers. i have 2 of hem going one looks like shes about 1 week from chop the other looks like she may go another 2-3 weeks. I can't tell if i have a mag deficiency or just regular harvest fade. they are both sitting at about 9 weeks now. Just wanted to get thoughts and opinions. Have some pics, hopefully they help. can upload more later.

It looks like too much Bloom nutrients. What are you feeding her how much and how often?

Hmmmm..tips are burnt but doesnt seem to bad. But im no expert.Its a coco grow they are in 3 gallon pots they are getting light feeding like 1/4 tsp/gallon of GH micro and bloom and 1/8 tsp grow. I stopped the cal mag about a week ago and im watering daily tapering off the nutes. That was for about the past two weeks. This week they have been flushed and will be getting water and molasses. I thought it might be just normal autumn fade until i saw the spots.

Those are completely fine

They're almost finished, no point in worrying about leaf color.

That's what i thought i just wanted some more eyes on it. I have trouble figuring out when to harvest. Judging by the trichs, it looks like it should be ready to harvest here end of week or mid next week.

I noticed that only your top buds on both plants are the only ones discolored. Are you using HPS? Notice how the rest of the bottom of the plant isnt yellowing too? Also it looks like a calcium on that leaf (brown dots).

I am using a COB led, i did notice that. Ive always used mh/hps in the past. Due to heat issues i thought lemme give LED a try. A experiment if you will. Instead of going the viparspectra or mars hydro (my budget for lighting) i thought id try these 3500k full spectrums. I definitely noticed alot more foliage with these vs the MH i was using.

More frost shots!

Too much light or too close.
