Any idea where the water drops on the leafs came from?
Leaves perspiring (guttation possibly)
Guttation is the appearance of drops of
water on the leaves of some
vascular plants, such as
grasses.
On some nights when atmospheric conditions are not conducive to
transpiration (humid and windless), and when there is a high soil
moisture, guttation occurs to maintain the flow of water and
nutrients through the plant. In that event, the water will exude through special
leaf tip cells, hydathodes in the leaves, forming drops of water.
Root pressure provides the impetus for this flow, rather than
transpiration pull.
Guttation may contain
minerals, such as calcium, in solution. On drying, this leaves a white crust on the leaf surface.
Guttation is not to be confused with
dew, which condenses from the atmosphere onto the plant surface.
How long did you have plants in seedling stage? They look awfully big for 3 days of vegging!
