You have root issues if you have to add ph up.If ph drops thats not a good sign,either feeding too much or root problems.

 

[rkymtnman]

So generally I just get a reading from the reservoir since it is a recirculating system

that is one of the issues with rdwc with different strains. ppm that is good for strain X might not be good for strain Y.

and you also can't tell if strain X is eating too. it might be nute locked and the ppm dropping is from the healthy plants only

and like @myke just asked, you sure you don't have any root issues on the bad plants?

Well also consider that I was forcing my pH to be so low. I was constantly shooting for a range of 5.5-5.8 and using pH down to do so

nice on the PH, give em a few days and see if they pick up.. if you notice any root issues at all add some Southern AG.. it's amazing.. i use a small bit during every top up (every few days) and never have root issues and also never change the water or any of that extra work.. no need if you keep your roots clean

That could be a possibility, I can take pictures of roots and share with you all.

But definitely not going to do 4 different strains again, and certainly not dealing with the White Truffle. This run was mainly to see which strain would perform best in my environment (White Truffle or Terple). Plus, pinkbox threw in 2 freebies so I just ran those too

you said you are using GH feed schedule. what additives are you using along with the 3 part?

Well.. one big thing is don't make too many changes at one time.. plants react in DWC very fast so it's nice to know what works, the stuff i have shared with you took me a few years to learn..

Basically i run 2 tents, 2 plants per tent and i try to keep 1 strain in each tent... i cut clones right after going into flower (just a timing thing and they come out fine) and if i like the smoke i grow out the clones, if not i start new seeds of something else...

P.S. if you wanna see DWC shine make a bubble cloner.. I keep my clones in the bubblecloner for months and train them while waiting on the main plants to finish, so when you are ready to move them to the DWC setup you have a killer root system in place and have already topped once or twice.. My plants usually go into flower 2 weeks after they get in the tent this way

that's what i started doing except from seed. get them ready to go into the flower room as soon as the first batch gets chopped.

 

[DrHill]

Pictures of the roots on the smaller ones 1st pic is Marshmellow OG, 2nd is the White truffle.

The terple on the back left looks so nice, feel like she has been ready to flower weeks ago, but I have been trying to be nice to the slow girls up front

 

[icetech]

Those roots are just perfection.. keep doing what you are doing and i am willing to bet with the slight ph increase the plants will get even happier

 

[rkymtnman]

not a root problem for sure.

 

[DrHill]

you said you are using GH feed schedule. what additives are you using along with the 3 part?

no additives right now. after all the reading and research on here I basically concluded that I would be fine with just 3-part GH and hydroguard. Atleast, that is what I kept reading.
I am about to run out soon though, and I have been considering ordering Canna Aqua Flores to use throughout the rest of flower.
Open to better suggestions on base nutrients and additives though.
Also considered Jacks, but I think I would like to avoid dry amendments for now. Pouring liquids is so convenient

I'm a jacks guy.. so no help here Cept losing hydroguard for AG.. think we already talked bout that though

GH 3 part is about as good as you can get liquid wise.

What's "better"? including dry products
and what additives should be considered?

i use jack's RO formula, liquid kelp, liquid fulvic acid, liquid silica and southern ag GFF

 

[icetech]

for me.. Jacks and AG from seed to smoke.. nothing else.

This was a older grow, 1 coco 1 dwc (i don't take many pics) same nute mix for both.. both happy. (not near done though)

Why does the Ph go down? First-time DWC. Foxfarm nutes. Set Ph at 6.5 and EC was at 1100 ppm mixed per FF instructions. Two buckets each with a different strain, in one the Ph drops in, the other one it doesn't. How come? Both are growing well but I keep having to add Ph up to keep it above 5.8 while the other one stays at 6.5.

Why try to keep above 5.8? That's just fine for hydro and if anything I'd be trying to drop the 6.5 one. I got spoiled using pH Perfect nutes for my last 20 or so DWC grows. Just check ppm and add a little nutes as it dropped and never even change my nutes for the whole grow as changes didn't make any difference at all and wasted good nutes. Damned if I'm making those f'ers any richer than they already are.

 

[Don't Bogart]

Why try to keep above 5.8?

You risk PH lock. And some nutes don't work well at such a low PH. 6.0 to 6.4.
