5.8 pH is too low for the plant to absorb phosperus calcium magnesium and molybdenum I would up pH ta about 6.1 or so

probably do better with a slightly highe pH ... all this craft stuff doesn't seem to work well, lol.. but when you do find a recipe that works, it sure is low-maintenance. this is the headache of such things... looks like interveinal with some rust spots? Assuming pH or nute-oveload isn't causing somem sort of lockout, looks like a magnesium deficiency. *maybe coinciding with aCa deficiency -- pls note these are two mutually exclusive molecules needed by the plant in different concentrations from each other..they are not tied together like most perceive... calcium deficiency is usally only spots... if oyu see othe coinciding symptoms it's moe likely lockout of some sort... if you see spots with interveinal, it's moe likely Mg... but this seems to have a few extra spots than what i normally see in other's problems with such things. so, you builda soil needs some adjustments in amendments o you need to learn to supplement that lacking component.. pick and choose. raising pH slightly could help too.. lower pH is when mg/ca start having usage problems in plant chemisty... still no idea why ppl recommend such acidic levells in soil... gives little to no oom below for error at 5.8. 6.0 to 6.2 is a better taget i don't care if it's hydro or soil... chemistry doens't change due to that superficial context.
