GG yellow leafs outdoor need help

Hi gang, I've tried to correct the issue on my own. While looking up issues here trying to match pictures etc. I was using an old ph pen when the yellow leafs started so I ordered another. Flushed with plain ro water, corrected the ph to 6.5 thinking ok problem solved. Well 3 weeks and 2 ph pens later I still have major issues. The plant is in ocean forest was getting ro water, calmag (every water) with 1/3 ff trio nutes once a week most of its life with great success. shortly after I started seeing yellow I switched to tap water (tap water is ppm 50, ph 7 constantly) and no nutes. I cut the nutes about 2 weeks ago and started tap 10 days ago (the last 3 waterings are tap). pics are from today, she just started budding a few days back. oh yeah she was indoor till about 2 weeks ago. The reasons I moved her out of the tent is I have autos in the tent on a 20/4 schedule. She was still yellowing in the tent. the rest of the plants are mid flower so the water schedule was diff.
any help would be great

It might be running low on N a little early, but not a big deal. I’d recommend feeding bloom nutrients starting at 1/4-1/2 so they have p and k to make bigger flowers. They start getting very hungry about now. You could add touch of N with cal mag if they’re yellowing too fast. The plant looks fine to me like it’s ready to fatten up those nugs

If you let it dry out really well a little too much, you’ll get some yellow leaves like that which is no biggie

ok thanks for the input. I got brave enough to ph the water today from 7 to 6.5 that was it. I will add 1/4 bloom nutes when she dries out. I can see how she would be hungry the buds are coming in fast. We've had great weather the past week really helped. I'll post an update pic asap.

edit: if she looks uneven my boxer had a little sample. it really is a shame but cant blame the dog, was able to save one of the lower branches which looks about 85% snaped but leafs are still budding!! The other branch was on the ground when I turned around. I foil sprayed some kelp and well I guess it taste much better than it smells!

Update: I took a couple of pics. she seems to be coming around nicely. I fed tap water and 1/3 ff nutes today ph 6.45.

Well it seems I jump the gun. previous post dec 12 I added 1/3 ff trio calmag, dec 15 tap water 3/4 dose calmag. Here we are dec 19 and she is not looking good. multiple leads showing red/brownish dots or speckles and bud production has slowed. It's been 4 days since last water should I flush again? This bud is pure fire would love to bring her back!!
