Leaves on buds are turning brown near end of flower

Hey guys I am just looking for some help . I'm near the end of my first grow with two plants. One is looking amazingly healthy and starting to yellow off now but the second plant has started growing brown leaves from the bud sites. I will provide pictures below so hopefully someone can help me out . It might be normal but I have a feeling it's something to do with nitrogen but I have started to flush now slowly taking the feedings away . I was using bio bizz bloom nutes for the flowering stage but only started showing this deficiency in the last week or so. Il post pictures here. Cheers in advance

Mostly the smaller buds down below the bottom of the plant that it is affected so far

Looks like boron def.

Will this be a huge problem for me over the next week or two? Not sure if it is too late to try and rectify the problem or maybe even chop a week earlier than I was going to?

Cheers

You can try a worm casting, kelp extract tea to perk them up that will cover the minerals and N and it wont build up in the soil so when you stop using it you can flush pretty quick.

Ok perfect I shall give that a shot, thanks for the advice waiting on my microscope arriving to see how long I have untill harvest I don't think there's too long left anyway as I have around 50% red hairs

Is the humidity in the room low? Boron has trouble up taking in dry air I read.

What week of flowering are u in

One is happy w the food regimine, the other wants more.....

That looks like you don't have enough air circulation, possibly creating a hot spot area on the plant. I feel that its because the temp is most likely too high with the combination of nutrients you are running. Are you running Co2? Do you have a lot of fans going? and what kind of nutrients are you using.

The humidity was actually quite high through out the whole grow to be honest I was running a large fan and a small fan on the floor under the canopy . I will agree there my temps have been pretty high throughout the grow but it's not had an effect so far . I intend to run co2 on my next grow as I am about to purchase a tent this was grown in my closet with a 600w hps sunmaster bulb so it was too hot in the cupboard but with the door left ajar and the fans running it was cooled down significantly! I was just into week 8 I shall put pictures up now of the plants before I just harvested them there . I got my microscope and the trichomes were just as I wanted them. I will upload pics. Of my grow now

All those look great, once you get the temps down and Co2 running you will be in business.

Haha cheers ! Thanks for the advice and feedback guys ! Appreciated
