100% Perlite Hempy question.

i kind of look at the timing like this...i plan for a week after i up pot till i flip to 12/12...for a reason.
i want the roots to get established, but still have room to expand after the flip. i don't want the plant to fill it's final pot while it's still in veg, i want the roots to have room to expand as the plant goes through the stretch. i think it stunts growth above the ground if the roots are stifled while they're trying to match the growth above ground.

That's an interesting theory. Or if the pant was well rooted wouldn't the plant use that root energy to produce more growth above ground?

I wonder if perlite packs like coco? I think I was reading that people are growing in smaller pots when using coco because the roots don't get bound like they might in soil.

Can you grow the same sized plant in a smaller container if you grow in Perlite rather than soil?

3 gallon is plenty for me rooted clone to chop. I need 4 months per pot and ideally I need to do it in a 2 gallon. Possible?

(I'm not in Hempy)
I up pot the same time as I'm going under 12/12.
I go from a root bound pot to one twice or more the size. When I dump the root ball at the end of the cycle its grown to fit or to nearly fit the pot. Roots In my experience grow quiet a bit, I'm guessing during the stretch and maybe at lights off, but I'm speculating there.
I'm not a big believer in up potting causing shock.

As an update, the yellowing leaves problem I posted here originally appears to be solved after I flushed and fed at the proper PPM. It's been a few days since I made that big water change and have lost no leaves since and the leaves that would normally droop didn't. I think it's fixed!

The lesson here is to measure my runoff PPM and keep those in the range I desire.

Just watered some veg plants at 750 ppm. Leaves drooping now on all.

I added water to the res and cut them back to 550 and hope they recover.

i know some people use a lot higher ppm than i do, and seem to have success, but 750 ppm would be the high point of my flower cycle...my veg plants never see over 250-300 ppm...
i'm feeding every time i water, and i'm watering every other day...they cannot possibly be using that much nute solution that quickly...they may be using that much water, but no way they need that strength nute solution.
check your leaves, any of them seem coarse, thick, rough? getting any strange looking "fading" along veins? that's the leaves being cooked from the inside out, by all the nutes they don't need but are forced to consume, anyway...

I sure hope not. I just watered them today and they drooped immediately. This is bad news for me if it damaged every plant in my tent again. .

don't flip out...many people seem to have success at that strength...it just doesn't work for me...not trying to make you have a stroke. if you aren't getting leaf tip clawing, tip burn, or edge burn, you probably aren't TOO high...but i would sure as hell be making sure i got a fair amount of run off every time i watered at that strength, that's a lot of dissolved salts to get rid of

i just hit 1.4 when i had to add a bunch of cal/mg to fix a Ca issue. but tha'ts with .2 well water.
i've always been a ppm guy, ec isn't "fine" enough to satisfy the lizard part of my brain....but (using the 500 scale, which i, and most of America do) 1.4 ec is 700 ppm... multiply by 1000 and divide by 5 to get ppm...

Less is More!

Totally agree, base 200 to 250 veg, 300 to 350 flower.
Can go over 1.4 when running PK 13/14 or KoolBloom liquid around week 4 to 5, but when adding Dry KoolBloom I run it so very low and it is used to replace Coco B in the solution. Today's solution is 580 ppm (1.16 EC) and that is with the change from Coco B to KoolBloom. Will run this the next two rez fills then should be ready to begin flush!
