For the sils I am about 6 inches above canopy, getting the odd leaf showing light problems, but I think that’s roughly about where I need them. Might move them up another inch or 2 and see if that helps.
Phed my run off on the other plants, looks like they are all around 1PH above my water PH. So I will be watering at 5.5 for the next couple of watering’s and see if that makes a difference.
