What are you growing in and why do you think your pH is the issue? The plants look hungry, they're nearing their end...though maybe you'd want the fade happening a little later, it could be worse.

Double the volume of pk booster/calmag to Canna a+b.

They're not starving, they're locked out, from too much booster and calmag.
Imho you need more a+b and less booster/calmag.

What medium are you growing in?

Booster NPK?

Canna a+b NPK?

Calmag NPK?

What do you mean by 9/10?

Gotcha.

Please, you need to list the NPK of each nutrient, it's just a name to anyone who hasn't used it before. It'll have a value on each bottle.

Your booster is 0-9-18 pretty sure, double check, I haven't a clue about the others.
Please list the recommended dose amounts for each bottle as well.

I'm not a DWC guy, but at a rough guess,

Do a res change.

If you're using RO i'd stick with the same amount of calmag.

Honestly, i'd probably cut out the booster completely and double the a+b. Maybe halve the calmag later on, just see how it goes.

Don't go too crazy on the a+b/ec just yet, you can always top it off a bit later. See if there's a positive effect first.
Doubtful you need the extra pk at all. If you ever do, I honestly think it'd only be to bump your base pk slightly, it'd be less than 1mL.

Hope it helps, good luck.

Edit: if anything is lacking in that npk, it's probably P. Imho the pk booster won't really make it any better, there's already plenty of K.
I've used Rhizotonic in coco before, It had a habbit of raising the ph in my pots, from memory I think it was 1% K as well. So just be wary and check if I'm right about the K.
You're at week 7, take it easy, it should be ok.

Yeah, i'd drop the pk.
Even 0.5mL / litre of calmag, top it off later if need be.
No if you've been supplementing a+b at 1mL / litre, i'd increase it to 2mL / litre. Then top it off later if it needs it.
Try to keep the ppm/ec around the same. Only increase the ec if you notice an improvement, if you think it needs it and use the ab to do it.
No problem, hope it helps.
There's a lot of great DWC growers here as well. If you keep having trouble, come back to this thread and one of them will surely help.
