PH problem

My Ph has been dropping to 5.0 about every day and I adjust accordingly. This shouldn't happen every day. should it? Could it be salts from my ferts? I do have FloraKleen but I didn't know if it would be safe while it is flowering (see pics) or how it should be done. My first grow soil free and need a little advice.

Your soil is prolly too hot.... If your soil is pre-amended and your adding nutes than its too much nutes ....Fox Farm will torch em..pretty sure florakleen can be done anytime but I've never used it for soil only hydro ..You can add lime and will bring ph to 7.can buy it at ace hardware...follow directions on package.Your plants look healthy and don't seen to be affected...I see lil burnt tips there but nothing to worry about as long as it doesn't start spreading down the leaves..good luck....

What do you mean soil free? are you saying hydro? if so what's your medium, rockwool or pebles, how are you feeding and what nutes are you using?

In any case those plants look happy. Slight tip burning here and there. If you are using hydro you're only about .5 points away from optimal (5.5-8.)

Hydro DWC. Rockwool. drip ring. Change water every two weeks. Used FloraGrow and Micro for veg, use 2 tbls of cha-ching added to 15 gallons. They look good but am having trouble maintaining a good ph level. Finding myself having to add base everyday. They seem to do well if I can keep it around 6.0-6.5.

Actually for hydro you should be at 5.8 ph, tho I'm not DWC but am hydro in pots with rockwool grow cubes my ph drops after each feeding and I have to adjust, it's always been that way and believe it's normal, at least for me.
