Beginner's Luck?

They are going to recover perfectly in just a few days. Give them some time to get used to their new environment and make new roots/drink the moisture from the fresh soil and they will peak up again!😊 I think they are looking very good for your first grow! 😊

Difficult to tell, but my guess would be a combination of nitrogen deficiency (the yellowing is quite uniform) and a little overwatering. Mg deficiency the leaf veins stay quite green and the rest of the leaf lightens.

They are looking happy and healthy. You can definitely top, just take off as little as you can on the top node. Sometimes you might need to wait a day or 2 for it to open up so you can cut just the tip off. That helps a lot for them to not take too much of a hit.

High KingMickey, You still need about 1 or 2 weeks to go. The best way to tell that a plant is ready for harvest is with a pocket microscope (60x is perfect). The trichomes change color from uripe (clear as glass) to ripe (milky white) to expired (amber brown). When 80% from the trichomes are milky white it is the perfect time to harvest. But if you do not want to use a microscope then the pistils (brown hairs) are the second best indicator. When 80-90% from the pistils are brown it is time to harvest. You still need 1 to 2 weeks till the ideal time for harvest. The buds look great buddy! Enjoy the harvest! 💚
