Quick PH question...but no probs YET

Hello everyone. Just a quick reference question: What does a lower PH runoff indicate?? My PH in is around 5.7-5.8. Just recently my runoff came down to around 5.4.

There are no signs of problems yet, but I test the runoff every watering and it's slowly coming down. Just a few weeks ago it was coming out 5.9-6.0 fyi.

The method chosen: coco perlite mix (botanicare readygro moisture formula), progrow, calmag, liquid karma, and an occasional small dose of peroxide. Am in week six right now...going through the transition. Water with nutes everyday at about 800-900 ppm this week. Handwatering to waste.

Any insight?

Thanks everyone

does whatever you are using to read your PH compensate for change in temp? Has the temp of res changed along with change in PH?

not sure if it compensates for it or not. It's a hanna tester, and while it does read the temp, I have no idea if it compensates.
I cleaned and calibrated it this morning, gonna see what it reads tonight after I did a flush last night.

There is no res, I am handwatering from water mixed nightly. The water pretty much stays the same as room temp.

kk that kills that thought :wtf:

LOL...ya but it's the thought that counts TT. Thanks for the brainstorm...any other suggestions?

I seem to remember reading somewhere that PH cnages as plants feed but cant remember if it goes up or down during the process

You are right pH will rise with time as plants remove nutrients

HA i knew i wasnt nuts :D

what happen if the PH goes down what does that mean?

What is the ppm of your runoff?

I have always nuted and watered alternately in a product like that. If your plant is using lots of water but not using the ferts as fast, it'll "concentrate" the ferts right in the pot. Acidic ferts get to be stronger acids, at least all the ones I've ever used did...
