Week 6 Outdoor Autos: What Now?

So 4 of my outdoor autos (green crack, gelato, northern lights, gorilla glue #4) seem to be doing well. They all look like this (below). Each have a bunch of bud sites starting and they’re hungry af. Here’s my grow log: https://www.rollitup.org/t/canadian-outdoor-auto-grow-log.1075823/page-2

I’m using the KISS method, straight up Maxibloom (promix/soilless)all the way through. GH says do a feeding twice per week with watering in between, then there’s a shit ton of opinions on how to feed on here. Recently, I’ve been feeding at 500-600ppm (sorry, I should be using EC but I’m guessing 1.0-1.2 EC if I go by my last EC at 480ppm/0.8EC) …ANYWAY…not sure what to do now. They seem to tolerate that feeding.

What I’ve been doing is feeding each watering, which has been daily or semi-daily with the hot 90f/30c weather, and then flushing with water every so often…I just go by observing the soil moisture. The plants themselves have shown no issue whatsoever.

I barely even touch the plants themselves: never move them, never handle them unless I am checking for bugs, etc. No LST. No trimming, no topping.

Anything I could be doing? I’ve been playing it super safe k owing in the back of my mind that autos can get weird. Should I add any other nutes? Will these buds get fat? About a pound each plant, right?

you could try asking others with experianc with soiless growing about folier feeding them is you dont want salt build up in your medium as i understand it. this should be a safe way to get more food to your plants in between feedings into your medium.
even if it were just seaweed solution without food added, it would boost your plants P/K with a small amount of N thats presant in seaweed solution.
thats what i do, followed by a plane water spray the followig day.
but get others points of vie on this b4 you doit, i live in the uk and we dont have as hot wether as other parts of the world
