Ok guys, I'm a first time outdoor grower in the U.K. We've had a pretty good run of weather so I bought some auto flower blackberry kush seeds. Germinated, them and then planted them outside on my rooftop balcony. All was going well up until about a week ago I noticed some small yellow spots appearing on the biggest leaves. The rest of the plant looks fine so I'm thinking is it down to too much sun or too much watering, maybe even some sort of nutrient deficiency? They are currently in Plagron light mix (as shown) and Also has a little bat guano mixed in before I planted. They do seem to be doing ok and growth has really exploded this last week or so, but the yellow spot really has me worried. Should I remove the leaves with yellow spot or leave it to play out and see what happens. As I say this is my first time outdoor so any advice would be appreciated.
