If the root mass is huge ..chances are the roots will have swallowed or engulfed the bubble stone or air disc.. Either add a second pump and 2nd airline or cut the existing air line and add a new line and air stone etc... I had similar trouble.. I am root bound in a 20l DWC..but gonna try n resolve that issue.. - STELTHY

They had, I just gave it a wiggle and freed it up then placed it underneath the root massIf the root mass is huge ..chances are the roots will have swallowed or engulfed the bubble stone or air disc..

Consider flooming. I know, it sounds made up. Read about it here..
Flooming vs Air stones
read a few interesting articles & threads recently, and figured I would post the info I found. Some of it is from koi pond websites but the info is based around oxygenating water, which is as critical for hydroponics as it it for living fish. __________________________________________________...

Ppm has dropped to 493
And ph has rose to 6.1
She looks happy,
gonna flip her in 2-3weeks

sounding good! just make sure the ppm's keep dropping a decent amount every day and don't raise it too high.

So the plant is almost ready to go in the flower room but she keeps looking a little droopy, I defoliated and applied some bends to her earlier but she just looks a little limp, I think i need a bigger air stone or maybe to lower the ph? She’s currently sitting in a solution of 6.2 ph and 490ppm temps are around 19-21c in the water
Also I noticed the older roots are quiet yellow and the new ones are white is this ok or does it look like root rot starting to form?

They tend to go like that over time but look fine. If rot starts you'll likely see dark areas forming and/or the roots getting slimy with bits floating around in the water and easy to break off.
Doesn't hurt to knock the pH back every few days then let it climb up again. Allows different nutrients to be in their peak areas for a bit and the plants like it.

2 days left and that should be an 8 week veg from original transplant
She’s a frickin beast, was just wondering wether I should get a bigger bucket for flowering in? Maybe a tote from the local hardware store blacked out around the edges? I plan to flower this 1 monster plant under a 600w and she’s currently in. 30l dwc bucket do you think it’s worth me transplanting her to a bigger Rez for flower?

If you're not having root problems you shouldn't need to move her. That one should work fine for the rest of the grow. Risk messing up those roots too if you do move her. A larger res would make it more stable though, and less having to top off and such, but it will also be more work if you need to swap some of the water like you just did the other day. Up to you really ^^

Do you think it would Increase yield?
Bigger roots bigger plant and all that

no, once you start flower the roots aren't going to grow much more so unless the res is completely full and barely holding 1 gallon of water, then i'd leave em be.

Roots actually take up very little volume in the tank. I did a test with a DWC once that had a huge mass of roots by chopping off all the roots at the bottom of the net pots and leaving them in the tub then filling the tub to a ledge below the rim. Then I removed the roots and measured how much water it took to get back to that mark and it was just under 2L in a 50L tub so less than 4% of the space was taken up by roots.
This is the tub I used and this pic was taken 3 or 4 weeks before cropping.
Roots grow like crazy after flowering begins. I've transplanted from 2gal to 5gal at week 2 and had roots coming out of the drain holes in less than a week. That was after sawing the bottom inch off the rootball to get rid of the long roots in the bottom.

So she’s in flower and her Rez is due a change tomorrow she usually gets a Rez if 5.5ph and 530 ppm with my tap water included in that
Shall I up her ppm or keep her the same until she asks for more?
hope everyone’s getting on ok with all this corona virus, self isolation doesn’t seem so bad when your a grower lol

I'd up the nutes with more bloom added. the plants eat like crazy during the stretch so can use extra of everything for the first 3 weeks then feeding drops back.
