Drain to waist experts

I've been doing a drain to waist system for a year now. I've been doing really well with big pots and a tight three day water sched ( water, no water, water) I was miss informed by many different sources on over watering. I water well before the pots are dry and the fresh oxygenated water forces the oxygen depleted water out the bottom. I'm running 15gal now and they get a steady diet of 5gals of water with 500ppm fert in veg and I work my way up to 700ppm in flower. The strain I'm running is the purps from bc seed king. I've found a pheno type at stretches a good 18-20 inches of rock hard baseball bats . Yield and quality that I've yet to see from anyone I know. I'm learning more every crop and I love everything about this plant. I know this was fairly vague with most of my description but i was wondering what out other people are doin with there drain to waist programs. Oh and it took me two full crops to find a strain that likes my system. Not ALL strains like drain to waist ........ Some hate it in fact but I'm pleased with purps.

I forgot to mention I was by no means an expert IMO . I believe it take years to become an expert.......... Spot problems and without the Internet solve them the instant they appear. Knowing and dialing a feed sched per strain to a Tee . Im just a novice who had a good teacher.

D2W eliminates the potential for nutrient lockout.

Until plants develop a substantial root mass (to support bud development) you don't really need to D2W, but during flower, it's very important as the plants are using a lot more specific nutrient elements, which can quickly throw the NPK balance out of whack, leading to nut lockout.

500 ppms is pretty high for veg. At 500ppms plants will sex without reducing light schedule.
I veg ~ 200ppms max of 400 ppms in late veg.

Check out my 21st Century DIY F & D, which does recirculate, but via an outboard rez.

I run drain to waste and us 3-5 gallon pots.... in flower I will water 2-3x a week generally feeding every other watering and each pots gets watered until 10-20% run off so that all the old fluid is washed down and new fluid is replaced.

Although sometimes I also recirc. using a flood table and my smart pots.... depends on the stage, ppm, and how the plants look and are responding.

You should be able to run stronger nutes but other than that you seem to be on the right track

Also in RDWC, during mid-late flower, the roots re sucking up quite a bit of the nutes & water. This causes the rez ppm & pH to skyrocket. Needs to be checked daily, if not twice per day
