Well it’s in the title… They were growing great but in the last days or so the leaves started wilting. They always showed some yellowing and I thought about nitrogen deficiency so I fed them with slurry but without success… Any tips?

    Thanks for you thoughts! I didn’t know perlite didn’t do anything for drainage. I honestly thought aeration and drainage were more or less two sides of the same coin.

      It will help, but depending on what’s in the organic part of the mix you could put perlite in at 50% and still find it was going anaerobic at the bottom of the pot, particularly with the new peat-free mixes. The best way I’ve heard it explained is that if you took a bucket of Angel Delight (like American “pudding”), how much grit would you need to add before it drained properly? A lot of these newer retail mixes just wet out into a slurry with zero structure to it. Making a free-draining mix is actually a huge challenge.
