Hi, just go at the website and look for their schedule. In my opinion nutriens are only "sidekicks" of a grow. Key for good growing is a stable soilmix with not to many nutients , but alot of benefica stuff in it. Then Lightning is another Key. Look for the Best you can get for your money. Keeping the right temperature and Humity is another key. ... and yes back to the nutrients , just start with 30-50 percent of the recommended dosage, and look how the plants respond. normally you just need avegetation fertiliser, a bloom fertiliser and a booster for the last 3 weeks. But i wont save money in the soil and the lights. Get some benefical stuff like calcium magnesium silica and molasses. more in the comments
