is everything okay?

a foliar spray with nutrients for no reason is tantamount to masturbation. if you have a severe Mg deficiency, a foliar spray is a good option, but regular provision of nutrients is best done through the roots. Instead of relying on a foliar spray, you should learn how to properly provide that nutrient to the roots in proper concentrations over time. It's easy to fall for nonsense in this hobby. there is a strong motivation to believe the bullshit that is often sold to us. Don't feel embarassed, just learn and evolve. We all believe or do something we think helps but is either useless or even a potential negative. i'd wager you fell into the 'defoliation' psuedo-science, too, but can't be sure. I'd suggest keeping things simple your first few grows and form a proper baseline of expectation to compare to when you try new things. this way you are more likely to discern when you incorporate some magic into your methods. Check out cocoforcannabis.com for their guides and articles. Even if you are not using coco coir, the information is relevant even if a soil grow needs a little different understanding than a soilless grow. A lot of things like, "to defoliate or not," are applicable to all types of growing methods. The gist of supplying nutrition is the same even if some options have more intermediary steps before the plant can actually use what is provided in the fertigation or amended into the soil. (that is one of their articles - "To defoliate or not...") It has some of the least amount of bro science and offers the right amount of skepticism to anything mentioned that doesn't have much proof to support. our hubris and confirmation bias is what is preyed upon by dubious vendors willing to sell you what you want rather than what is real.
