Grow Mediums How to fix a ph imbalance in a auto pot

[JimmyJames77]

Hi there, I'm curious if anyone has encountered a ph imbalance in the autopots. Due to the way the salts rise to the top with this system I'm pretty sure I shouldn't do a traditional flush to the get the ph sorted. My res is sitting at 6.0 I have one tray sitting at 6.1 one at 6.3 and two more at 6.2. My original mistake was having a bubbler in the res which I have since removed (pays to read the instructions lol) I do have the aero domes air trays installed as well.

My thought process so far is to fill the res with 20l ph it to 6.0 and just feed straight water for that time.

Thanks for taking the time to read this and hopefully provide some guidance

Well, my first question is, are your plants showing any problems that cause you to worry about .1 to .3 pH difference from your res. Next would be what medium your using. Myself I've never worried about a small drift like that in my res and I've also never pH'd right at the trays. If your plants are doing good I wouldn't worry about it until a problem shows.

Thanks for responding, my mango smile is looking very sad lately yellowing leaves very tiny ect, the meph wedding is looking the best of all four, my royal gorilla is starting to show the same sorta deficiencies yellowing with brown spots and the lambs bread has just started showing a bit of the same symptoms...only really started showing about second week into flower. I'm using the remo system for the foods

You might want to visit the Infirmary section, fill out the info form and provide pics of the trouble. We have a few experienced growers that monitor over there to try and help out. I have no idea about that nutrient line as I have mostly done soil and MegaCrop one part and am experimenting with a different nute product now.

If you're just going into flower it sounds like you might need to boost your phosphorus. I ran into this issue in my current grow. Been using Jack's 321 and I contacted them about my issue and they recommend a bloom booster for 7-10 days at flower then switch back to regular feeding.
