pH shouldn't be an issue in cloning due to the fact there isn't really any nutrient uptake. Any nutrient uptake is generally done through foliar sprays while the rooting is taking place.Thanks a lot! I basically soaked some rock wool cubes in (tap) water for 15min or so, then took my cuttings, dipped the tips into clonex gel, and stuck them into the cube and waited. They sat on a tray in the tent with the big plants.
Most of the how-to guides made a point to talk about the pH aspect, so thats why I assumed that was the issue. Apparently the manufacturing process gives the rock wool a naturally high pH, so you need to soak them in water pHed to like 5.5 to bring it back down. Or at least that’s what the guides said.
I’m not too worried about it right now, I’ll get it down next time. I’m still just excited to see these plants through to the finish.

What were your temps like and your RH? You need to keep clones in very high humidity if possible. I agree that pH was probably not your issue.
You may want to reference this chart:
Sorry @jl01 i saw your post, never had time to reply, and lost track of what journal it was lol. I hope Slytown was helpful with the chart!
it almost looks like a magnesium def. I see the purple stem on the leaf, is there other stems or branches that are purple as well?
looks like a calcium deficiency to me...
If you grow with bottled nutes, I would splash some extra cal mag in there next time. If you are in soil.....top dress some Gypsum and Epsom Salt on the plant. I try to keep the Gypsum at a 2 to 1 ratio of the Epsom Salts at a minimum.
Short answer is, no.it's possible the leaf coloration could simply be due to genetics? Or possibly that temps are getting too low overnight?
yes, both good products for organic gardens... The gypsum/epsom method would be very easy to overdo and end up with an unbalanced soil that no longer can hold other vital nutrients. The calmag supplements come in with a much lower calcium and magnesium content for a good reason.Also, I'm wondering if anyone has used CaMg+ by General Organics or CalMag by 'True'? I'm going to go ahead and give them a low-dose of a cal-mag supplement and I'm wondering if anyone has used these for organic grows as opposed to gypsum/epsom blend that was suggested above. Just want to review a few options before going with something.

Stick to a tablespoon of Gypsum and a teaspoon of Epsom Salt and you will be fine if the general health of your soil is good.
That combo is about the only thing I do in soil so battle the rare strain that shows high usage. Takes the Gypsum a while to be used up.....its not all soluble and has to be broken down. If you use the powder instead of the crumble type, it gets broken down relatively quickly.
