Trace element deficiencies like iron would yellow new growth up top. This damage is not nutritional. It’s from some pest sucking on your leaves.

Grafting perennials makes sense. Grafting annuals makes far less sense. Time is money.

The picture with the damaged leaves show an issue with your pH. When the pH swings quickly out of range leaves will deform, twist and form random brown splotches. This will typically lead to lockout and other nutrient deficiency symptoms appearing. Check the run off next feeding to get an idea of where the pH is at and go from there.

Congrats on winning. That’s a serious upgrade.

20 watts isn’t going to grow anything but a tiny seedling for the first week or two. How much space are you trying to fill? 200-300 watts of any reputable LED brand would cover a 2×4 foot space to veg a few plants. You need about 400 watts to cover a 4×4 space.

Defoliation is not topping.

Your pH and mineral buffer is out of range for sure as 40% perlite is way too much to use in a mix with Grow Dots. Your not growing in soil at this point when your mix is half inert. Perlite has no ability to hold nutrition so your growing media can’t hold on to much of the slow release nutrition Grow Dots are providing. When you water, you’re just washing out minerals as they have little soil to stick to. Your mix is more for cyclical top feed or flood and drain hydroponic systems. They look under watered as the media is probably drying out too fast with that much drainage. There is no fix when you start wrong. Sorry.

Autoflowers have no place indoors. They are garbage. When seed sales became legal in Spain in 1999, auto breeders tried to take over that market. That’s how it started. Lazy fucking growers took the bait. If you want to grow a seed once, ‘autoflower’ a photoperiod plant on 12-12 schedule and save time and money with better results.

Looks like leaf miner damage. https://en.wikipedia.org/wiki/Leaf_miner

What does your media consist of? Not watering to run off is how you get salt build up which causes pH to swing out of range. Plants consume far more water than minerals. Salts form as minerals concentrate during dry backs. Proper run off insures excess minerals and salts get washed out between waterings. 10-20% run off is what you want when watering in from the top. You can’t easily over-saturate a media when top feeding an established plant. Young seedlings and clones need a little break between waterings when their delicate roots are not established in a container.

Roots pests attack and stress roots as quickly as anything. When you’re doing everything right but the plants are still dying has to be frustrating af. That’s always a possibility but when I read 40% perlite with Grow Dots I knew what was most likely the issue.
-
Over and under watering can droop leaves the same way so that’s why it’s important to have as much info as possible. Knowing his soil has 40% perlite, we can reasonably assume they are not being over watered.

When just the leaf blade edge yellows (before turning brown when untreated) is from a lack of potassium. Plants are very potash hungry throughout it’s entire life cycle. When plant roots get hurt, nitrogen and potash are the first signs of an issue as they are needed in the highest amounts. Calcium deficiency shows up as tiny brown looking burn spots. Magnesium deficiency shows as interveinal chlorosis (fancy way of saying yellowing between leaf veins as it looks like tiger strips). Mag has yellowing along entire blade while potash just yellows edge.

If I were you, I would find a way to water more often with little runoff. You can’t over-saturate a media with that much perlite. Grow Dots has all the nutrition the plant needs. We just don’t want to wash it out. Ion exchange occurs in water. The organic matter/soil can hold and ‘buffer’ nutrients for later use. Your plant will be fine without spending more money on nutrients. Just can’t let the media get even a little bit dry.

Looks nothing like a male.
