I left this week for three days left the Berry’s in 24 light schedule I did not trust my timer it’s acting up but I’m gonna grab some massive bloom buster to add I got gelato going to right now they are a lot thicker but these Berry’s are tall and sexy cheers
Looks nice. I think Remo astro flower is a good bud booster it has the right proportions of phosphorus and potassium for bud growth and bulking up. Usually mid bloom is the best time to give them an extra pop of PK. I would be careful a few of the Blackberry diaries that I've followed shows they don't like too high of a ppm of nutes. Good luck with your grow.👍
