Spots on green crack?

the one on the left looks to be nute locked and one on the right wants more,to me.different strains so this might be correct. left needs a good flush and you can increase nutes a lil bit for the right. I don't know which one is one the left,it just seems to be suffering,soil ph must be too acidic,clean it out,make a good flush until your runoff water looks cleaner.don't forget to add small amount of nutrient solution after flush.go easy on nutes for that one but keep feeding the other one bloom nutrients because it looks like it would thrive in good conditions.dry leaves on the floor is a good sign that it wants nutes.

Always check your water's pH. If it is off it can cause nutrient problems. It is hard to see with the lighting but it looks like you might have a calcium and magnesium deficiency causing the spots on the leaves. The light green color of the leaves could be a nitrogen deficiency or possibly molybdenum. I'm seeing a lot of colors in your photo that might be from the shading and burple lights but molybdenum is a more rare problem but can cause the leaves to have orange/red/brown coloring around the edge of the leaves. Still, first check your pH to make sure it is right because if pH is off it can cause so many other problems.

Slow down Rh if you can..at least 10%. Check water ph and follow right nutes schedule 👌🏽 She needs only water now
