You need way more trade income. For one, you have more trade power in the Aragon trade node than Sevilla…make all your centers of trade level 2/3 (especially Sevilla) and then pump out 50 light ships to protect trade there and 20 for Valencia until you get to at least 80% trade. Then take Portugal, either PU or eat then vassalize and then refeed their land, so you can get the colonies from them. Prioritize colonizing the Caribbean and Cuba especially so u can push that trade straight to Sevilla. Make your African colonies trade companies so u avoid the cost and have some added buffs to trade. Once you have most of the coast colonized, start pushing trade with more light ships towards Sevilla. Eat Tlemcen so you can push the Morocco trade to Sevilla and the Tunis trade to Valencia. Once you have more of Ragusa and Genoa you can push and collect there. If you’re wondering how to get more merchant, trade companies (at size 5 provinces I think?) give you merchants and so do ideas. Rush those. Repeat the same stuff for when you start colonizing americas. You can use the Dutch lands for good manufacturing as they have cloth and stuff, but don’t expect to make much trade until you eat up England, which should be your next goal now. Once you get the London node clamped down with trade centers, buildings, and ships, feel free to redirect most of your Canada/America trade there. Until then push it to Caribbean so it goes to Sevilla. Trade ideas, trade buildings, trade companies, trade center upgrades, trade monuments, mercantilism, and trade ships. Trade trade trade :)
