Clone problems

Clones are having problems. They are as if burning up. I use root riot cubes. I use the clonex solution at 15 ml /g and pH at 6.5.

I soak them and then dip my cuts in clonex gel.

Temps are 78 degrees

Some strains are ok some arent. Have no idea why they get sick.

Id say we need pics to help here. Setup sounds ok except you didnt mention whether you have them under a humidity dome but i assume you do. What kind of light? How far?

Oops just realized those clones mightve died in 4 days.

Sorry when I posted this thread it was having issues with uploading. Here are the pics. Clones in same condition

You don't pH root riot, that is pH burn on those leaves.

I have always PhD my root riot never had any issues?

Its normal to see some deficiencies while cloning ime. Naturally different strains using different amts of each nutes would show different deficiencies. They look fine to me
