Since you are running a flood and drain, I would fill your res with pure water (no need to adjust pH) and let that flood your buckets about 2-3 times withing a period of 10-15min, then to get the rest of the salts that may have built up towards the top of your hydroton I would pour some pure pure water from the top of netpots. This will be good start, but remember to limit yourself on the amount of time you spend flushing because you will then want to refill your res with your new nutrient solution and run the system ONCE more to give them a feeding.
Unlike soil, it is unnecessary to 'wait' for your medium to dry out before feeding again since hydroton holds very little nutrients for long periods of time.
Make sure you PPM doesn't exceed 400 at this stage. Once you start to see healthy growth I would incrementally increase your PPM each week until you level out at 600. (so about 50-100 PPM increase a week) Once in flower, you can incrementally increase this number to 1000 PPM.
Glad you got those meters in Tree. You will really have a handle on your grow now. Things should be looking better from here on out
