I've been vegging a few plants for 7-8 weeks and they are about 3ft tall and 2-3 ft wide.

3 of my biggest ladies drooped after draining/refilling my hydro buckets and have not grown at all in 3 weeks. Turns out I somehow messed up the PH in those two buckets after adding a new supplement. The ladies were sitting in 7.8 ph water for a few weeks. My roots seem to have a small bit of root rot as well although it's hard to tell from the dark nutrient stains.

A load of fresh roots have grown since but still no growth.

My second pump & 8 stones come tomorrow as well as my Canna anti root rot + Hydrogen Peroxide mix, so I guess that will sterilise any left over bacteria. A week ago one of the fans blew off the ducting for 6-12 hours & when I went in the grow room (8 x 6ft) & it was 29-30 degrees C. That visibly caused a bit of stress so I got temps & heat symptoms back to normal and still no growth! They look a bit weak and droopy still

It might be worth letting you know I picked off a few of the big fan leaves that were dying/drooping due to lack of oxygen.

it's been 2-3 weeks since I had a PH/Root Rot problem identified & I'm wondering if I should ditch them for a few vegging ones I have in my room (will add 6 weeks to the current grow).

What do you think? Will they recover?

The bottom girl looks like a Nitrogen Def. Just got some today in the mail so hopefully she will sort her self out (literally hasn't grown for 3 weeks.

The biggest plant (which looks like a total mess right now just got super cropped to expose new sites as I removed the main wilting fan leaves.

What do you all think?

Dude, I don't want to disappoint you, but you have serious root problems in there! Root rot, pH fluctuations, ...

What is the temp of your grow area and the solution in your reservoir? I recommend using Hydroguard or similar products for your issue.

I think hydro experts can give you a better help, if there is still a chance.

Funny you say that though mate, one of the plants before had rootrot and I've grown a few times before so I know what it looks like/feels like and these two pictured just seem to be died that colour, they are perking up now after hydrogen peroxide & cannazym liquid. I'm wondering it it was just the start of root rot?

The PH problem was for 9-10 days and the temp was only a matter of hours and nothing really changed in the roots then just they got stunted. Thx for your help I'll ask the hydro people.

I've gotten root rot, and it's best not to add anything. Especially Hydrogen peroxide or bacteria like hydroguard/aquashield/great white. Its usually the watering/drainage that causes it.

I recommend watering away from the stem and more at the roots. Make sure if you have rapid starter seed plugs or rockwool that they are not soaked, and try to water them less. Just keep them barely moist with a spray of 5.0-5.5 PH water.

Water far away from the plugs/rockwool, because the cuttings need very good drainage. Which is a little bit harder to provide to plugs/rockwool in dwc than ebb.
