A lot of yellow / dead leaves mid flowering

Hey everyone,

I've been searching for an answer and I've seen to come across a lot of conflicting information. I've heard that some yellow and dead leaves towards the middle / end of flowering is normal.

This is my first grow. I have 1 plant. I'm about 7 weeks into 12/12 with a 400 HPS bulb. The buds look good. However for the last two weeks or so I've been losing a lot of leaves and the problem seems to be getting worse everyday. First they turn light green, yellow, then die. I've probably lost about 1/2 the leaves on the plant. IMO this seems excessive.

Temp is usually in the upper 70's low 80's. It has never gone lower than the mid 60's or higher than the upper 80s. Humidity is usually around 30%

I've been using Fox Farm Beastie Bloomz for the last few weeks. I've been using at 1/4-1/2 the recommend dosage, every time I water. I'm also using blk strap molasses. I'm debating about switching over to Cha Ching for the final few weeks.

Any thoughts? If necessary I can post a pic.

Thanks

At 7 weeks into flowering the plant is winding down in its life cycle. So the leaves going deficient is normal right now. I'd feed them only water for the next week to 10 days so the remaining nutes can be used by the plant and then harvest. Any bud shots for us to look at?
