Plant Issues

Some lower leaves becoming yellow and fall down during the flowering stage it's absolutely normal....But I also see a Mg deficency.. Check your CalMag..

Common problem i see, i also have it a lot lol So, have you had times were the soil was super dry? And water passes out the bottom? Looks like that's happened to often here. And what most ppl do, to think the fix is to add loads of water. So the plant is going from sucking dirt, to choking on water, and they're the typical signs of it As if all of top growth is good and that's all down below these are the causes.
