Brown leaves

Five weeks into flowering. Five Gallon pot w/ Ocean Forest soil; Indoors; Started seeing browning during this past week. Cause? solution? Using Fox Farm nutrients (Tiger Bloom; Grow Big, etc)

A couple questions: Are you giving them any calmag (Kinda looks like it could be a Ca deficiency)? Have you done a flush on the soil to leach out the salts from the fertilizer??

Have not used calmag and haven’t flushed … yet … although thinking that might be the next step. Possible build up in soil as I do use ph down In my water?

PH up (or down) really doesn't affect the salt build-up, it's a product of the synthetic nutes. If I was you, I'd give them a good flush, water three times the volume of the pot, this will re-set the soil, then go back to feeding with calmag. Unfortunately, the affected leaves will not recover, but hopefully they won't get worse.

Thanks. Will try flushing

Just curious if this solution helped?
