Are these ok for autoflowers?

[tangielover]

So here's the thing I've never grew anything by myself and this is essentially my first grow.
So here's the thing we are at exactly 31 days from seed and my 2 autos are starting to flower. I topped 1 of them and did some lst on the other just to test to see what would be better for this strain.
But essentially I'm wondering if these plants are getting adequate care or if I need to make adjustments for the next grow or current

They look real good, most first timers have trouble with autos, but you're looking great! Maybe cut back a hair on the water, let the soil dry back pretty well before watering again. The object is to make the roots search for water (expands the root system).
