I have white spots on some of my leaves after watering? Could this be the dried up water?

Yes, it is dissolved mineral salts that are left behind once the water evaporates. Cheers, Organoman.

One of the 4 is drooping but only in the afternoon a few hours before the lights cut out. In the morning she isn't drooping anymore. Normal behavior or odd? She looks normal otherwise. Considering a flush this week. Thoughts? I'm definitely not over/underwatering.

Which deficiency?
So I've asked before if it was a magnesium deficiency on the GC and got confirmation based on the early pic, but now I'm starting to wonder if it is? Buds don't seem to fatten up either. Maybe calcium or potassium? Lights too strong? Overfed? Shouldn't have given Vega just flower

Defoliation during flowering and overall plant health
Should I proceed with defoliating this plant on day 28 of flowering? I am always a bit reluctant to doing this as I think it stresses the plant a bit too much when it is supposed to be producing flowers, but I would like to hear from you guys.

Why DP's leaves are so small?
Hi guys! Do you have any idea why Durban Poison is growing so slowly? I am suspicious I might have hurt her during the transplantation. She has 3 pairs of leaves and she is healthy green, but her leaves are very small...strange from a sativa. She has the same age as my Durga Mata
