i recently transplanted from red solo cup of roots organic soil to big pots of empire builder by sanctuary farm and feed. these picture are from a couple different strains, on some leaves are canoeing both ways and culring down, and on another leaves are turning. both these are deficiencies ive known to be from unbalanced PH, so i did some research and other people were saying the empire builder had ph problems for them too, so im pretty sure thats it, but i just wanted to know if anybody else had any ideas if this is something copletely different. and if it is a ph deficieny what is the easiest way to tell if ph is too high or too low, and how should i flush my medium to get it balanced.?
