Hi
@BazookaJoe! You're having a slight Nitrogen deficiency from the past weeks, you did not feed enough N when the plant started to stretch, and as a result, the lower leaves are yellowing/dying. This is not really important since those leaves are not getting access to light anyway, you can tuck them out and prune the lower bud sites of your babies. Now about your invaders, it's all about prevention, I know it's too late for you but next time you may plan a prevention strategy from day 1 to harvest. Neem oil is a really powerful organic pesticide, but you don't want it to touch your buds / bud-sites, so it's a bit late to spray anything onto your plants. However, you could use a sponge and slightly treat above&below the leaves. 10-12 drops of pure neem-oil mixed with 1ml of soap (for the oil to adhere on the leaves) in 1L of water, use this mix with your sponge and you'll get a chance to get rid of those invaders. Hope this will help, keep us up-to-date and happy growing 👊
