Here's my trick: don't ever stop checking that pH and adjusting it when necessary. That's really the only "trick" you need in any kind of hydro, and not just DWC: pH matters more than anything else. Other than that, plants grow themselves and no tricks are necessary.
In the decades that I've been almost exclusively a hydro grower, I can confidently say that pH problems are what fuck most things up. Hands down. More often than not, when I see people posting pics of their hydro plants and asking what nutrient the plant is deficient in, the answer is "several," because the actual problem is with pH.
So that's my advice. Take it or leave it.
did malawi x caribe in a DWC checked my tap water ph once for the whole grow, thats it,,,used GH nutes as directed on the label. KISS
Wow!! So i just use top the nutes directed on the canna table for low/medium! Ty buddy
Read what hush said in post #4. Then read it again. If you have any issues then follow what hush said first. Calibrate your meter often in the beginning so you can know for sure that your pH is correct. I've killed a lot of plants with a meter that wasn't calibrated.
I like my pH to swing, 5.2 to 5.9, but I aim for 5.5-5.6. My plants start to slow down over 6.0.
My medium is 50/50 lava rock and screened kitty litter(calcined clay).
I'm using a modified ppk system so I'm not sure how much of what I do for pH applies to other systems.
For pH up I use agsil16(silica) and phosphoric acid for pH down. Nutrients are Jack's and calnit.
