So close to harvest problems

Hi. I have a pair of Girl Scout Cookies that are showing around half milky trichomes and are showing some distress. Some leaves are yellowing and then drying up to a crisp. I’ve added some mag and some phosphate, not sure if I used enough. They’re in soil, under LED and otherwise look ok. Any ideas

How close to harvest do you think you are? Some yellowing of leaves usually happens, if you're close enough to harvest you might do more harm than good trying to fix it.

I figure 2 - 2 1/2 weeks. The plants look productive in bud but the yellowing concerns me. You’re probably right to let them finish as is.
