Northern Lights big bud

Hi @Mbrow with that yellow light I don't see the colors of the plant very well. It seems to me that everything is fine except the beginning of a magnesium deficiency due to the yellowing between the veins of some leaves and the burnt ends curling upwards,apply some calmag, but as I said, I can't see well with that light. put photos without that light. good luck mate 👍
