I thought you were in soil.Hi bill hope your well and thanks for your info. Well I was speaking with shed about ph situation on mediums and with mine which is sphagnum peat, peat moss and perlite apparantly you dont have to ph. So maybe i didn't give them enough amounts or they haven't had a lot of nutrients to feed off .not sure but they do seem to still have a nice green colour to them just drooped so probs thirsty lol. I phd it to 6.1 and ppm was 490 so they should bounce back with this feed.
Are you running Pro Mix?
If so that's a ph of 5.8.
It's basicallyhydroponic.
No soil.
Do you have a pic of the bag?
Stay safe
