Marks on leaves

Autogrowzstarted grow question 6y ago

What are these marks? Soil grow. It’s on some of the leaves 3-5 inches down from top. Ph is correct after adding food to water. But soil ph is low. How can I fix this and what is it? Thanks.

The mark's are likely ph related. To raise use a little dolmitic lime at a time, until your runoff comes out where you like. Can get at most garden centers. Cheers

Late Flowering Stage Deficiency or Nutrient Burn I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.

Brown spot on leaves I'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis. Someone could help me?
