Trouble keeping pH up in flower

[darrenking241]

Just as the title says, I’m having trouble keeping my pH up, it’s going as low as 5.3 atm, Anyone think that I could set it at 6.2 now and let it take itself down to a reasonable pH over the course of the week or should I use pH up/silicate product.

usually PH going down means your EC is rising..... or you have root issues in my experience. As above please let us know what system - DWC. NFT, etc your in :)

[darrenking241]

Please include as much information as you can.

Medium you grow in.
Type of system you use.
Nutes you use.
Any other additives
Ambient temps
What you using to circulate or aerate your feed.
Is your system recirculate?
Starting PH.
How you adjust PH.

I grow in rockwool with hydroton all ph adjusted before grow, washed rinsed the lot, rdwc system 50 l capacity, AN sensi bloom, hydroguard, ambient temps creeping up lately with the heat outside 30 degrees, I have 1400 lph water pump and 20 litre per min air and I was starting at 5.8

Check your roots for brown or slime please.

Roots are a little brown off the b vitamin sup I used but defo not root rot, no slime, smell etc. And ec was rising by 1 point every day so I brought it back down 1 point maybe should have been 2

if you stabilise your EC see if the PH continues to drop. I dont know what hydroguard is - is it like liquid oxygen/h2o2? If not I would give them a dose.
Are the leaves drooping at all? can you add pics :)

can you take some with the lights off and camera/phone flash? few odd looking leaves there but might just be the HPS. ive never used that hydroguard but appears to be for what I was saying, odd it can adjust PH tho
