I've got all purpose fert for nutes (NPK 20-20-20 of course) and im using that for veg. 1 week or so into flowering ill switch to a good flowering fert. Know any good ones?

As for the perlite you're probably right. Roots do love oxygen, thats why hydro grows so fast no? (Well part of why). However when i transplant them to their final pot (3 or 5 Gal) i will do that. Otherwise i'd have to stress the plants to get the perlite in.

Unless you can add it without disturbing them? However i cant imagine how.

When i stick my nose up to the plant i can smell the citrus. No wonder they call it cali orange.
