Spots on the leaves

Hello.. Hope you are well.. Just had quick look at ur dairy n noticed ur giving her rhizotonic still.. This will raise ur ph a bit.. Tbh the dots look like a combination of nutrients to high(copper spots on leaves) and heat stress(curling of the leaves).. If possible try to open vents etc to cool grow environment down a bit n cut bk on the feeding at each waterings.. Dont 4get to alternate between food and plain ph'd water wen groin soil so not to create nutrient build ups.. Stay safe n gud luck around harvest time .. 👍🍀
