PH

I gotta question for the PH masters on RIU. Here's my gear and situation. I'm running the AB+C General Hydroponics Flora series. I veg for 5 weeks with ppm starting around 200 on week one, and end at around 700 at 5 weeks. Also I will inoculate some great white during weak growth stints, and use H2o2 a few days before a res change. I have 3 tents in perpetual rotation for around a 100 day cycle. DWC standalone buckets are my method because its honestly just so damn fun. I grow 3 plants at a time germing new sets every 4 weeks. Both of my flower tents are sealed and have two inline fans recirculating the air between them. Co2 enriched flowering cycle at 1500ppm. I check ppm and PH twice a day. At lights on and off. Res temps average at 65F. All my limited factors are at optimum levels.

My question is that for the first time in two years my PH did not change in any of my buckets for 8 straight days. Does that mean I got it dialed in? PH of 5.7 in all. Water levels drop but the ppm remain the same as if its drinking and eating at the same rate. I've been slowly raising nutrient levels through the entire growth cycle. And cap at out around 1200. Change reservoirs every 10 days and sterilize the air stones.

Just stoned and looking for thoughts other then my own.

Nicely done sir... I'd say you got it dialed in. Good Luck

Sounds like the sweet spot but keep in mind that it is the sweet spot for that stage. At different stages the plants will take different elements in different amounts and slightly higher ph in later stages will allow for what they want.

Thanks for the input guys. I do like to raise the PH to 6 around week 3-4 of flower to maximize the potassium and magnesium uptake.

What i found that works the best is for first three weeks go 5.6-5.7. Next three weeks 5.8-5.9. Then last weeks go 6.0-6.1, that is when they really like the extra potassium.

That's a good schedule. I may try that with a control plant next group.
