My guess is nitrogen deficiency supposedly you should feed veg nutes 1 or 2 weeks into flowering just a little and week it off kinda

This can happen in flower. If the new growth is all looking good. And it doesn't seem to spread rapidly I wouldn't worry! Happy Harvesting!

Yellow/gold spots on top fan leaves in bloom phase I noticed a couple of the top fan leaves have got some small yellow/gold spots developing. I've been using the same Bloom feed for this plant as my 3 Bears Smile which is 8 days further along. I'm wondering if that might be causing the problem and how I fix it.
