Hello, first time grower here, I noticed problems with my ph rising bach up to 7 around 20 minutes or so after I lower it. I have a 2 plant DWC system, I feed once per week and my feeding routine is as follows
-remove plant from bucket
-dump out old water
-rinse out bucket with hot water
-add new water
-add nutrients directly to bucket and stir
-adjust ppm
-adjust ph
and that's it, however, this week(plants are on week 5 of flower), I noticed what appears to be a calcium deficiency and when I checked my ph I noticed it was at a high 7 so I adjusted it back down to 5.8 but when I checked again around 20 mins later, it had gone back up to 7 for both plants. Ppm was also sitting at around 1900. so I went through the process again only for the same thing to happen. any help would be greatly appreciated also bear in mind, i'm about as new to this as it gets so please be kind lol. Happy growing!
