Quick health evaluation

Hey. Bit hard to give my opinion with those pics buddy. The issues can be hard to notice early in my own grows. But, what I can see. The edges, (they're light green as where the tips at some point??) If so, with what I can see you can confirm it urself. Those signs usually are attributed to your roots finding it hard to breath. Let you soil dry in more and as it does air is drawn into your sub allowing your roots to breath. So, you're using soil right. So just 1x strong npk feed a week. And then just low EC (either calmag r enzymes as follow up feeds to come behind your NPK bloom nute feeds) Also, tilling the top will help your top soil dry in more quickly and will increase o2/co2 to your root zone. That's the only thing I cm barely see. Idk how much you know about growing. But, don't do any defoliations until you're a few days out of pre flower (upwards growth)
