    Hi recently i have new problem in my cursed grow.
    I aded nutes to the water, than checked ph and added some down.
    I'm poping in after few hours. Doing check and...
    Ph 6.9 and film of white powder on the bottom of my tank.
    :confused:
    Please help.
    What could be a reason.

    Just to add. I changed water, put some down and then added nutes. Effect.The same.

    First your PH should be 5.5. Second what type of hydro are you using? The white powder indicates to me a build-up of salt meaning flush-it.

    I added nutes and adjusted ph so it was correct. It looked rather like some hemical reaction. Tank was cleaned b4 all.
    It happend with two types of feed. Ionic, and good a and b, I got from my hydro shop. I'm suspecting heater, fore some reason but can be something else.
    Basicly it looked like something reacted and conected in salts sucking acidity of water.

    PH chart - 5.9 = optimal:

    you do 5.9, I'll stick with 5.5. My last grow produced 600+ grams from 3 plants.

    Bloody impresive.
    It just convinces me that, aldough it's hard at begining it's worth it.
    It's more likely that I accualy added to much, as I was going with labels.
    Finaly got ec meter so life should be easier.
