i am growing in a 10 gallon container changing water every 2 weeks. the PH of the water slowly rises everyday. so every other day i adjust it to keep it at a good ph level.
Why does the ph rise?
Of course when i change my water i put the nutrients in it. but do the plants take up the nutrients, therefor not having any left in the second week? should i be adding more nutrients? say i change water on week 1, week 2 i add more nutrients and start of week 3 i change water again and start over.
this is my first hydro, please tell me if i am wrong.
i have not been doing this, i have just been adding nutrients when i change the water and keeping the ph down. but i am curious if the plants are taking up all the nutrients leaving nothing left for the second week.
Also, what is the ideal PH level, and ideal temperature for the water.
o btw it is a bubbler system.
