J/w, what could be the cause of rust spots on leaves?
Maybe 3 dots of a dark rusty orange on each leaf of some of my seedlings.
Could it be a deficiency to potassium? Heat stress? Ph?
owning a website means nothing,wouldnt even say light to close either,when lights to close in my opinion leaves curl upwards and light bleaching occurs.
And???????? Your point is?????????
Why don't your pics show?
Good job Gilligan.
How does light being too close make rust colored spots?
Usually that is the late stages of a K deficiency.
