I have some weird leaf discoloration on a couple of flowers that are directly under the center of my light. What do I need to do? Also this is what my lowest (younger) leaves are doing at the bottom of the plant. Any tips? included a pic of a flower in the corner that looks fine.
This is either common genetics, a simple sunburn, or a phosphorus deficiency. The latter of the three is the most likely given your stage of flowering.
Remember, you're growing sativa, so you probably have 5 weeks or so left before harvest.
