Fert to Bloom

Hey Growmie, During flower or any stage for that, It's best to feed every other watering to prevent build-up which can cause deficiencies in your plants. Hopefully, I answered your question and remember ..."Happy Growing" and "Free your mind one puff at a time"

Not an expert in soil but I would say max once a week, going easy on the ferts and a watering between feeds to keep your salts from building. Some use ferts that almost take you through each stage without having to keep adding, just watering
