I would wait more, they didn't fatten up u gonna get airy buds when you harvest now. Give them 2 more weeks maybe. You need to check the trichomes look for minimum 90% milky and some amber, but this depends on you I prefer a headhigh this means I wait always to get all milky and maybe 10-15 % amber. You can buy a magnificer for 5-10 € $ at Amazon with 30x-60x zoom this works good for me. ✌️🏼
