another new medium? ughhh

So I am having a minor problem. I first bought 3 clones from a dispensary in which they were rooted in rockwool. I let them grow a little longer in these rockwool cubes then took the cubes and by advice here, planted them directly into my soil.

For veg soil I am using Scott's potting soil. I dont know if anyone has used this before but I did for my last grow and I didnt see that many problems so I was relatively satisified. However this time, I am getting all sorts of weird yellowing/browning and I am thinking it is for sure because of pre added ferts in this soil... The new leaves are coming out green so that is promising but I am thinking it would be best to transfer this over to a new soil mix. Something with just vermiculite and perlite(more bs i have read here)...

i was curious as to what consequences there might be by transplanting them into a 3rd medium and if I was to do so, how may I go about doing it?

Right now the plan is in a week or two, to xfer all my plants to final pot/soil and then flower them in their new pots/new soil..

if your staying in soil it shouldn't be a problem, dip em in einstine oil if you want to make it super smooth but not nessecary.. rockwool works fine in soil, keep postin i'd like to see how they turn out

maybe just stressed from the transplant? I use fox farm soils after starting in grodan(kind of similar thing)....works for me
