It will probably burn seedlings, but if you use it with established plants you should be ok. Do a search on google for LC's mix.I'm gonna be using promix the one with the water crystals mixed into it. Was gonna mix in some earthworm castings,10-10-0 guano. MG bonemeal and peace of mind fruit and flower 5-8-4 and dolomite lime. How much of each should I put per gallon. Rep to anyone who can help
