Autopots help!!!!

hi every one
using autopots - coco and clay pebbles as my medium and canna nutes


just had a question about the auopots system, i filled up the tank yesterday with 30L of water and nutes. ph to 5.8, i also placed a air stone in the tank,


and now the next day, i checked the ph of the tank and its at 6.4 is that normal? or is the air stone coursing that? i just was wondering becouse i dont want to go in there every day and sort the ph out


thanks for any help much appreciated !! have a good day all!

200 views no reply?? lol come on some one must have faced this problem

reporting back

the issue was the cal mag, the cal mag raised the ph very high and its hard to maintain as it shoots right back up the next day

im feeding 2.5 ml of canna a and b to 1 liter of water and 1ml of rhizotonic to 1L of water, at the moment the ph is very stable its just the first 1 or 2 days i have to adjust just by a little and rest of the week the ph is stable

with some research i found ionic coco nutes are a very stable with they ph but may be not good as canna so im still thinking of switching to them, any one with some report to the ionic coco nutes most welcome

peace
