Help I have looked all over but can't pin point what is causing this hole in my leaf. I found out that my ph was a bit high just solved the problem and my timer messed up and lights were on a bit longer then normal . Idk what or which would cause it.
No I try not to get any on the leaves I water it at the base of the plant just a little water when the top inch or two of soil gets dried out. My humidity has been running a little lower then I like.
