Hi guys
Need a bit of help with my ph issue.
Im currently growing 7 plants in dwc, each are in 19L oxypot buckets, with 1 air stone in each, plants are around 6/7 weeks in veg from seed, using shogun nutrients A&B, silicon and katana roots with green emerald calmag.
Growing under 3 lights which are 2 x 600w dual spectrum hps and 1 gavita pro 1000w dual spectrum
Room temps range from 19c - 25c
Water temps with lights on are reaching 21-22c, usually use silver bullet in my res so i never worry about root rot, I'm going to buy some tomorrow.
Humidity 30% -50% using a ram humidifier
Ec/ppm 1.0-1.2
Ph level set at 6-6.2 and rises to 6.8/7 within 24 hours, plants look fine and are healthy drinking flourishing until recently I've noticed a few rust spots which indicates calmag deficiency hence why i started adding calmag supplement, I'm having do PH down daily, I've grown in dwc few a couple years now and have never had this issue, I've read online this is normal but im thinking it's abit of a drastic jump in ph to be "normal" ???

Am i wrong?

Roots are nice and white and strong root mass with no browning.

Any help is appreciated

Its normal bro. Im always adjusting ph down during late stages of veg & up in mid flower stage. But you should set the ph between 5.5 & 6.5 because some minerals like manganese phosphorus & boron are more readily available to the plants at levels below 6.0. So ideally you want to use all the ph range between 5.5 & 6.5

All good bro. Yeah it’s weird how it goes up in veg & drops in flower. Its almost like the plants know what they need at different stages & try adjust it themselves its fucked up boggles my mind
