Looks nice but 4.22 gallons is way to much. Even more than my two 3gallon plants I regretted having and thats just 2 plants guzzling 60 gallons in 3 days or less. Plants will get a false signal to grow much larger than they need to because its not like soil.
If they have super slow dryback able to be fed 2x a day that would probably be the least pain. People say it will give soil like results treating coco like soil but IME they grew great just humoungus with no need for all that media as it will not root through all that coco.
I grow in pots more than 4x smaller than that and only barely rooted tightly through the one gallon with more space for roots to grow still. I would flip those relatively soon if youre aiming for 2x2’ size plants in your 4x8 if I recall your tent size right.
Here are pics of my 3gallons 6 wk veg.
Do u mean litres that seems like a lot, that’s like 40L per plant a day for an 11/12L pot. I know people who run it in 16L pots and don’t have any problems feeding once a day they said to me.
But yeah I’m running into a bit of a problem that the ones I transplanted are pretty big and ready to flip but the other strain is a lot smaller, I have a small 90x90 cm tent that I might set them up in so they can veg a little longer be a tight squeeze but they’re not quite big enough to be flipped yet where as the other ones are
Yeah mate they look good, do u mean 6 week flower is that buds on them?
