Discoloration on new clone growth

I've had similar problems on rockwool and in Fox Farm Light Warrior.

This is in FFLW, with ~5.5pH water, cuttings dipped in Clonex and held under a humidity dome for about 2 weeks:

What's going on here?

soil pH is 6.5-6.8
hydro pH is 5.5-6.0

you got it mixed up.

that on your leaf is the effect of too much humidity. it will come back as long as you have adequate ventilation.

Keep your ph between six-three and six-eight. Transplant it into some more nutrient rich soil. FFlW does not contain the nutrients your plant needs.
Light Warrior is acidic, as is my water, because I believe it's necessary to prevent bad microbes before they've rooted, no?

This is the only cutting from a group of 12 in FFLW that has the issue (92% success rate). Couple this with the fact I've seen several other people successfully using Light Warrior for seeds and cuttings, and I'm left believing that it does, in fact, have the right mix of aeration, nutrients and bennies to help roots grow strong.

My suspicion is that a drop of water fell from the dome onto the growth tip and caused a light burn, given that the splotches are in the same relative positions, their expansion 1:1 with the overall growth of the plant. Can anyone confirm this?

If I am indeed running the wrong pH (I move over to ~6.3pH with the first watering after they're out of the domes), can someone point me to a reference that suggests rooting pH should be the same as during veg/flower?

Everything I said is based on my own personal experience. LW is fine for the initial stages once you have a rooted clone, but I have encountered problems the more days my clones have been in light warrior past rooting.

Once I did transplant them to FFoF cut with perlite, they were fine.

If you find something that works different, good for you.
