Just harvested my 4 autos here in France. A guerilla grow and I was absent. 4 more seedlings will be going in the same pots at the weekend. Will empty the pots, mix up the soil and refill the pots.
Will use a liquid feed until September when I return to the UK. Before I go will sprinkle a granulated feed on the soil. It's very old so won't have much nitrogen left in it, but potassium is inert and doesn't lose it's potency. And potassium is bud feed.
They will be ready end October when I will return. I hope the weather will be kind to me and not too much rain. Had budrot last year.
