Hi, i have notice for a couple of days that some of the sugar leafs and calyx are browning/burning.
could this be excess of nut? it dont appear to be mold, because if i pull some of those leaves, they stay firm in place.

Thanx!!

I think maybe a calcium imbalance

Already did. im posting new ones:
could be mold, but humidity is around 45%... temp is around 86 though, maybe heat stress?

So you did, my bad. Never seen photos attached like that on this site. Have you scoped it? Gray mold is a possibility and it doesn't always go real fuzzy when the humidity is lower. Possibly light bleached I guess, not heat stress. Barring any weird environmental changes, I'll go with gray mold. Should get fuzzier if that is the case. Sorry I can't be more definitive.

No, not all over. Just in a couple of places. random, but only at the top of the bud

Is this all on one plant? What kind of lighting are you using? What is the light distance from the plants?

all in one plant. COB 150w in a 2x2. the tallest bud is at 8 inches, but all the 3 bud tops, that have this browning are lower buds. i don't think it is light bleach. it is advancing very slowly, it is dry and crisp, but it stay firm in place if you try to remove any dead leaf.

Can you make a picture of the whole plant or even better the whole set up so we can see the light proximity xcetera

I fix mine by only giving water for a few days with cal-mag only

you have locked out calcium

I did not mix my gh nutes as recommended causing the problem

Your plants are sickly my guy, this is the result of many problems combining weakening your plants. Im no expert but you need to test soil and water In/Out

Wouldn't those huge fan leaves less than a 1/4" below them show atleast some sign of light damage then?

Exactly my thought, they have only the slightest bit of canoeing from heat. I've seen rot that looks kinda like that, but I'm only guessing..

Edit: So I Googled 'MMJ Bud rot pics' and I would say it's Bud rot
