Nute burn from using old soil?

Started seeing yellow/brown spots on a couple lower leaves on both of my plants (wedding cake fem, gelato cookie fem). I'm surprised because i've been a little more conservative on nutrients than i was for my prior grow, paying closer attention to the nutrient schedules and ppm and ph.

What do you think? Attached pics

Journal from the past few days:
  • 9/8 (Day 35) - both were still in 2-gallon pots, 1/3 gallon of water
  • 9/9 (Day 36) - nothing
  • 9/10 (Day 37) - 1/3 gallon of water w/ FF Grow Big, FF Big Bloom, Emerald Harvest Honey Chome (1/2 of whats on their schedule), Great White Mycorrhizae. pH range 6.2-6.3, ppm range 1130-1220
  • 9/11 (Day 38) - 36 oz water, before going away for weekend
  • 9/12 (Day 39) - nothing
  • 9/13 (Day 40) - came back to drooping plants, mistakenly had my fans off and the humidity was really high, possible heat stress too. Soil was completely dry, so i took the opportunity to make my final transplant (2 -> 5 gallon pots). I used a mixture of mostly old soil from my prior grow and a little bit of new soil. I was running out of new soil, using FF happy frog. Sprinkled mycorrhizae straight onto the root balls and in the transplant hole, watered with 3/4 gallon of water each.
  • 9/14 (Day 41) - first time noticing yellow/brown spots. conditions seemed dry, first layer of soil seemed dry... watered with another 3/4 gallon each 5-gal pot to get runoff.
  • 9/15 (Day 42) - 3/4 gallon nute mixture with FF Grow Big, FF Big Bloom, Honey Chome, and a little bit of Cal-Mag. Nute mix range - 970-1040 ppm, 6.58-6.65 pH

That's not nute burn. It looks like a combination issue. I don't have time to diagnose it this second but combination issues should be the track you follow with others.

I'll check back later to see who said what.

The yellow leaf is from the 9/13 incident (far left) Other than that I see nothing to worry about. The third picture might be from a little burn from the new soil.

appreciate it - do you mean literally "combination" like combining the old and new soil, or a combination OF issues that could be coming up? thanks!
