First time grower. Alaskan Purple Strain. Using ffof soil with RO water, Feeding Fox Farm Trio, Cal/Mag and PH UP. Cycle between water and feed every 3-4 days. In 4th week flowering and have not been able to get PPM over 800. Since started using Tiger Bloom haven't been able to raise PH much over 6.0. Plant seems fine with big white hairs everywhere and smells awesome. Concerned buds won't get big if do not find way to raise PPM. Concerned about possible nutrient lock out if I do not raise PH. Any helpful comments and advice would be appreciated.

I dont know. Flushed plants and ending run off was 6.4. I did a feed and water since with both ph'd at 6.8. The ph run off on both was still 6.0. The leaves have not gotten any worse. I have to feed them again soon. Not sure their is anything else I can do for them. They're not flowering at the desired speed. Trichomes are milky white, but none are amber. I may have to flower past 9 weeks, but that's probably not a big deal.
Is the issue now resolved?
Add just a pinch of baking soda to the water raise the PH. And I mean a pinch. All natural baby.
My fan is near plant. I thought maybe colored leaf change was a nutrient deficiency because haven't flushed soil from using Fox Farm nutrients yet. I read about possible salt build up could cause nutrient lock out. I am so confused. Need to either water or flush right now and I don't know what to do.
Just fed big bloom with tiger bloom today. I don't remember the exact ppm of solution, it was either in the 300's or 400's. I ph'd the solution at 6.8 On one of the plants the run off was 600's PPM and run off ph was 6.2 ,and other plant run off was 700's PPM and ph was 5.8 Not sure why the ph keeps coming back low on the run off. The plants look fine except the browning of some the outer edges of leaves near the bottom of the plants. Bought a ph soil meter and it doesn't work. Keep fumbling around with the idea of flushing with sledgehammer on next watering. The Fox Farm feeding schedule says I should be flushing, but I haven't done it once. Being my first grow not completely sure what to do.
I assume you're giving the plant a half dose or quarter dose of nutrients according to their feeding chart. Simply up the dosage. Depending on which bottles you're using, a full dose in flowering is well over 1000 PPM.
