Ph problems in 100l tank

[Aberboy77]

Hi I’m having problems with my ph in an autopot 100l tank I ph to 6.2 in a 15 l bucket and add my nutes that way but what I’ve Noticed my ph fluctuating with temperature drop on water in the tank the ph is rising as the temp lowers and I heat the water back up above in the region of 15-20c and the ph will lower as the water heats is there anyway about this or what am I doing wrong I’m using coco perlite mix with shogun feed. Also growing in the attic this is why the water is getting colder
