Sudden brown spots all over plant in week 5 flower

[SpawnOfShulgin]

Ph between 6.0 and 6.5 (using indicator solution because my ph pen broke so exact ph is hard to tell)

Fox farms ocean forest soil and blue planet nutes. I have only been giving water and calmag for the past week or two since the leaf tips showed signs of burn.

I will include a link below on another thread i had made where alot of my grow is documented to provide more info if needed.

Looking for any insights on My 2x4 tent (2000w enjoyyeild LED)

Dude you need to tone down the resolution for your pictures! I had to go screw the old lady for a while and wait for the page to load. I'm going to just repot my babies and grow them in the grow room under my new LED light until I start flowering the big ones. Nice clean pots standing by for...

Tell us about your media, feeding schedule/amounts/ppms/ph? Something you are doing could be causing a lockout, never know unless you provide all the info.

For veg they were fed according to Blue Planets label with every watering. I don't check PPMs (lazy i know). I do have a TDS meter though i should start using it.

The link i provided above documents everthing pretty well. It started off just me looking for advice and morphed into a journal or sorts.

Media is FFOF Soil. I

Miscalibrated ph pen?

Mine started acting up so i have been using General Hydroponics indicator solution. I tested the runoff and it seems to be between 6.0 and 6.5 which is consistent with the ph i water with.

The tips of the leaves were burned a for a week or so and slowly progressing before this began. I am not sure if this is related.

Is it possible too much salt build up (which resulted in a burn) is locking out nutes? I never really flushed, i just switched to calmag and. Phd water
