I give a dose of bloom nutes as soon as u see the first signs of flower. Those plants already have budlets. They’re nice and healthy, starting to show signs of nutrient deficiency. If you notice the leaves are getting some yellow spots. I’d give them a light dose of bloom nutes with some CalMag and start mixing up your ph. It’s not good to always be the same, it should fluctuate high to low in the 6-7 range so all the nutrients in the soil are available. Nice job so far!
