I think that the frost is mostly genetics, most the clones are picked on frost being a big factor these days.
First you have way more experience than myself but here is my 2 cents.Hey guys I got a question , View attachment 18872262 do you feed your clones when they’re in the cubes? or do you let them fade Till they have roots?
When it comes to growing information I’m always a virginFirst you have way more experience than myself but here is my 2 cents.
I love rockwell switched from Root Riots to rockwell and my success went way up.
I use a tray that where the cubes don't sit in any water.
I water the cubes every 3 days with cloneX mixed as per directions.
I don't cut my leaves , just like you. I read a pretty good study that said the only reason to cut/trim the leaves is if they touch each other in the tray.
I normally don't get a fade in the leave color.
