Howdy Lunchbox. Feeding schedule I was constantly changing, trying to figure out what worked best for me. The OG and Sour D fed differently then Jack. Lots more cal mag, quite a bit more nitrogen. Jack i didn't feed cal mag using R.O water throughout the entire cycle, rooted clones to harvested flowers.
Typically I transplant in about 900-1000 PPM, any strain, into a 4 or 6 inch block. Once they pop roots through the bottom (3 or more) Ill transplant them into the buckets of croutons, and feed aroudnd 1000 ppm until I gradually go up. I typically max my PPM out at about 1800 in flower and flush with plain PH'd RO whenever I want. I've gone weeks without flushing but typically I try to flush after about 4 feedings. Obviously if I see anything I don't like I back off and give them some plain R.O ... they actually seem to really enjoy the fresh aqua.
I could water really heavy and miss a day. The plants were about 5 feet though, give or take, so they get thirsty rather quickly...the Sour D especially, everything else could go 2 days NO PROBLEM. Sour D needed HEAVY watering to go 2.
