6th week of flower.
Mostly top leaves but some middle. No lower leaves.
Help me out here guys.

Probably light burn. What kind of PAR numbers are you hitting? You should be measuring if you’re not already, get the Photone app. I like to stay below 1100 umol (around 45-50 DLI).

The ranges are 22 to 42 dli
The pics are before and after I did a compost tea by Xtreme. She had only a leaf or two with very few rust spots before I used the tea. I did also add another 150 more watts the same day as the tea so not sure 
what’s going on. Kept 18/6 whole grow and did I not half FF feed schedule.
She hasn’t been fed nutes since 3/5 as I thought she would be on the shorter end of the strains 8 to 10 weeks til harvest. Been giving only ph’d water with cal mag and molasses for almost 2 weeks now.
Maybe I cut nutes too soon. Run off PPM was 683 last night. Is it too late to maybe bump her back up on flowering nutes for another week?
Trichs are clear. She’s super sticky but thinking I got a little ahead of myself and that maybe it was
a phosphorus defiency.

Most deficiencies start from the bottom or middle leaves, but light burn happens top down, which is why I leaned that way.
Does the 150 include any UV? Either way, you might have wanted to ramp those in. She might have caught a little sunburn from the extra intensity.
Could be nutes too, lose the leaf and see if it progresses.

I would say calcium def phosphorus tends to work it way from the edges of the leaf in ward its looks very close to potassium def aswell

You need a diffuser to get a more accurate reading.
