Clones in fox farm? Will it burn plant?

I Just finishes grow box. I bought fox farm soil and happy frog soil. Would it be ok if I mixed happy frog with fox farm and start growing clones in them? I herd it would be to much for clones and shock or burn them?? Anyone have experince?

Never mixed but have had cloans on ff ocean forest and did great....wish I could be more help?

I mix them 50/50, and don't have any problems. I get burned leaf tips, because the soil is quite rich, but not quite rich enough to actually hurt them. I'm thinking about going with just Happy Frog or Light Warrior, for the babies, then go OF/HF mix, afterwards. That should work perfectly.
