Leaves Yellowing week 4 into Flower?

Need some help on this.....Getting yellow leaves in week 4 (30 days into flower) - I am used to some yellowing but this is a little earlier and more than I like. Wondering what I did? I started from clone right into Fox Farm Ocean Forest, no issue with soil being hot or burning. Did not feed for 4 weeks then added a Fish Emulsion 8-1-1. Vegged for one more week then flipped to 12/12 did not feed next 3 waterings (one week). I am in 2 gallon smartpots, I water every 3 days but now it is more like 2 as they get bigger and starting to flower. Used Dyna Grow 7-9-5 for next two weeks during stretch along with Pro-Tekt Silicon. After Stretch switched to DG Bloom 3-12-6 with pro-tect. I am on a water, water feed schedule now and 1/2 strength. Check the runoff of PH and it is around 6.2 to 6.5...always check PH of water (have been using combo of tap and distilled water) Temps high lows are 66-84. It almost looks like I need more P, but now I think I wonder if I had too much and it locked something else out? Not sure why I fed with Fish Emulsion week 4, that Fox Farms soil has plenty of N. This started at the very bottom and has worked its way up to middle now. Just the bigger fan leaves, everything up top looks green and buds seem to be forming on schedule. This is (2) Edelweiss clones under a 400W watt in my closet grow. Any suggestions, normally a little yellowing at this point wouldn't bother me but I am sensing something is up?

a little yellowing is ok at the bottom of the plant in flower from what iv read

so long as the buds are still chunking up i wouldn't worry

Worry about the buds not the fucking leaves.

There is a direct correlation between leaves and buds thats why I am a little concerned....but i wont worry unless it gets worse. I am hoping it is not something that will slow growth of buds

Week 4 and nobody is worried? By week 8 the bud leaves will be turning yellow too. The plant is using N from those lower leaves. The plant could use more N imo, the decision is up to you.

Needs more N.

Added some veg food into bloom mix and did a couple water feed water and 1/2 strength seemed to do the trick!
