pH Going Down

[gangadoctor]

hi all, i'm growing in a 9 pot hydroponics system which has a header (brain pot) which is automatically topped up with a 100 litre res via a float system.

the main system has an ec of 1.3 and ph was set at 5.8. the 100 litre res has an ec of 1 and ph also at 5.8.

how is it that each morning i go in to check everything the ph drops to 5.3. each morning i re increase the ph to 5.8 and each morning it returns to 5.3?

it's driving me crazy!! GRRR

salt build up using ph down???

Try lowering your ec/ppm down. That's how I keep my PH steady by adjusting my ec/ppm.
