Normal Potting mix and a third of the mix I put sand and I put half a handful of some slow release nutrient beads and some lime.

My last girl loved it and she was very healthy no problems besides some aphids
But in the end she grew some nice potent fruity buds

Just don't get whats happing this year

Only different things are they sprouted in a very cold week
And i didn't sprout them in seed trays like i did every other year.
I sprouted them in the Pots I normally transfer them to after they veg for a few weeks.
And I planted a few months later than I normally do.
