help, leaves are turning yellow and brown.

This is my second plant ever. The points on the leaves turn brown then leaf turns yellow. Starts at top of plant. It started at flowering stage. PH was high and I got that lowered. Been adding CaliMagic also. It's still progressing. What have I missed?

Needs calmag for sure. If pH is off correct that also. The leaves already damaged will not get better. Just monitor for the brown no longer progressing. In general it looks like it could use a defol.
