Looks good, don't over water ! I still have to remind myself not to over water. I forgot to water once and killed 12 seeds and it still hurts
So know I want to over water to compensate !
...this is good advice, as new growers a valuable trick you need to learn is the 'heft' method of watering which, simply put, is jut to learn how light your pots feel when they are dry, once you learn this all you'll need to do to decide whether or not your plants need watering is to lift them up, if they are light, they are thirsty.
...i'd not recommend it with plants so young but if it were older i'd suggest you let it dry out until it started to wilt before you watered next, just so you could feel how light 'thirsty' really is. ...mj needs a definite wet/dry cycle and it does not like wet feet, so while you shouldn't wait until you see wilting before you water, habitually, it is worth doing once to learn that 'heft'.
peace, bozo
