Going to chime in on the perlite thing as well.
Like an old member, dongle69 liked to say, perlite is a crutch! And she grew the shit out of some coco herbs.
No reason for it. you can feed multiple times a day with 100% coco. I've done both and will never waste time and money on perlite again.
Once roots are established in the pot you cannot over water, I don't care if you water ten times a day, it's just not going to retain enough water to cause problems. Every time you water you're just pulling more oxygen down into the root zone. It is what make coco so special.
If it's not too late dump out a pot and stick it back in straight coco and see for yourself.
Just my opinion anyway. Looking great, I'll be here watching.
It's too late to do that with what's been planted, but I can throw another plant in and do 100% Coco to test.
