Yellowing Leaves Browning Buds

[blinkin]

Hello all! Noob here to the forums but I've been lurking around for quite some time. I've got a bit of a problem and was wondering if anyone can help.

Buds were looking perfect but have had some discoloration almost overnight. Leaves turning yellow, buds brown. Anyone have any idea what this may be? Thanks in advance for any help.

Sounds like mold caused by caterpillars: Tops Of Buds Turning Brown And Dying

Yeah. From that thread:

BT= Bacillus Thuringiensis

Very effective and only affects caterpillars, but once they are in the buds ........

I'd still get some and use it. Might not help much with this grow, but you will need it for the next one.

I get the concentrate, Thuricide, but I also use it for horn worms on my tomatoes. Apply it every couple of weeks at least and after a rain for sure.

Easy to find products that contain BT in Lowes, HD, or any garden shop. Dipel is one and a lot of 'natural' products. Harmless to anything but caterpillars.

Worth a shot if you can confirm this is what it is...

looks like a lot more than caterpillars might be going on there - what are the temps day and night? what and how much are you feeding? what's the soil? what is the water/feeding schedule? e.g. feed, water, feed, water or f,w,w,f or f,w,w,w,f? how long has it been flowering?
