See this is where I feel like i'm getting a bit of conflicting info from this site.The only thing I can guess at this is you're missing a micronutrient, like boron, sluphur, similar. I can only guess because I haven't seen a plant struggle with this kind of color. It could also be water related as that soil looks like it's compacting and won't breathe much. plants need 16 or 17 different elements in nutrients. If you're soil has none, you might give the fertilizer dynagro a try. just a real small amount like 1/8 or 1/4 tsp in a gallon of water. maybe you can find the small 8 oz. bottle because when you use so little, it's hard to justify buying the quart.
My first thought would be that there are PH problems. Look at the mottled yellow spots on some of the leaves.
But some of you are saying I shouldn't even really worry about PH in soil.
But then some of you are saying peat moss isn't really soil.
I really just need to buy a ph meter I guess.
Are digital ones worth it?
