Slow Growth

It looks really wet. Also very small amount of soil. If you have been keeping this wet throughout their life so far, you may have "washed" or leached all the goodness out of the soil by now. Let them dry out a bit, then replant them into bigger pots, filled right to the top with soil, so there is plenty of space for root development. They should recover perfectly once you transplant them. Hope this helps.... Organoman. PS - some plants, such as Sativa dominant types have pale leaves naturally, however this does not apply to your white widow plants, I just thought I would include this fact in case any Sativa growers read your post. 😎

Also you might want to not go under 70 degrees at night/day time or have such a big 10 degree change while in veg. Have that 10 degree change later in flower. Good luck!

Get a proper wet dry cycle going and you should see faster growth. Looks to me like your overwatering them. Let them dry completely out before watering each time. You got them in starter cups so it shouldn’t take to long for them to dry out. Cheers💨
