Certain mixes can run too hot, I’ve personally not had it happen.
The key is in research and listening to what other growers have tried. They will tell you what will run too hot as they have tried it.
Generally you follow a feeding schedule so you don’t give too much nutrients at a time. Its all based on successfully following a plan. But if you know there is a *TON* of fertilizer in the mix you went with… The solution would be just to not fertilize for the first few weeks to a month so the seedling has time to grow before it needs the nutrient doses.
