Hi Doc and gang,
This question needs a little background, so please bear with me.
Because there’s no PromixHP available here, I used pure sphagnum peat moss for my mix.
I mixed a half batch of kit soil.
Some of you may remember a discussion about this at the time I realised my (minor) mistake.
PromixHP has 27% perlite in every 3.8cu.ft bale.
I should have removed 1/4 of the SPM (which was also 3.8cu t) and added the perlite in its place, but I didn’t.
I added perlite to half the bale (25% of the amount of SPM), added doc’s recommended amount of limestone powder as buffer and half the 1st run ammendments, and 20pounds of castings.
What this means is that I ended up with a mix that’s a little on the light side in terms of calcium buffer and the kit amendment (not the castings, they should be fine).
At the time Doc, I think you didn’t see it as a problem so it’s probably not. However;
I’m starting to see some motley coloration on the leaves (pale and dark). It’s not extreme, but it’s more noticeable today than it was yesterday. I wonder a few things about this:
I wonder if it’s an issue;
I wonder if the slightly light base soil might be the reason, and if it is, whether drenches can remedy, and;
I wonder if it’s something else.
Today is day 41 - last drench was a TP 3days ago, yesterday it got a brix.
I’m not panicked about it at all, just observing and wondering.
It was a guess---educated, not wild---with the soil. It does look to me like a root issue, however. Here's what I would do:
1. Prune off lower leaves and branches
2. Give a Rescue Drench when it dries out
3. Take not of the new growth.
That should set things right.
