You've got bugs; probably some type of mite.
I get moths, and they lay eggs that hatch into catapillers/worms, that walk around the leaf and chomp. The lady bugs eat the little bastartds! And I will get the white flys very soon, also have bars just bc of where I live and the fact it's a shed.
a 5-5-5 blend could have it in it. The 555 only refers to NPK values. It doesn't however mean that it is void of calmag
It's dr.earths organic all purpose 5-5-5 vegetable garden. But it's probly shit, gonna step my game up on my second grow, this is first huge grow ever and any grow in 6+ years. After doing much research it looks one or all of these calcium, magnesium, phosphorous, potassium. Can't be sure tho. Gonna get some liquid ferts from the local hydro store.
Here's some more info to help with diagnostic. The stocks are weak, like if I step over the plant and my pants push it over it stays over for a little while till it turns back around.
