I'm afraid more information is needed to thoroughly answer your question. Small white spots are the initial symptom of a number of diseases and pests (white flies, mites, mold, canker, etc.)
Are the spots on the leaves? or the fruit?
Do the spots grow? or turn another color?
Are there insects on the underside of the leaves?
Do the leaves turn brown? curl up? fall off?
Are the spots fuzzy?
Wind burn, transplant shock, sunscald. Tomato plants that are grown inside need time to adjust to harsher, less controllable, more intense living conditions outside. Don't immediately transplant. First let them adjust, still potted, to the morning sunlight of a protected eastern exposure outside. There may be a nutrient deficiency if the plant's leaf-poor. Sunlight's harsher, and more bleaching, to smaller plant surfaces and to fewer leaves. So fertilzer may be needed, and soil moisture checked. Fertilizer ingredients must be in soluble form, to be taken in by plant roots. Their application makes them present, but plant-unavailable, in dry soil. Adequately moist soil particles speckle a screwdriver or soil probe that's stuck into, and then removed from, the ground.
It's called root primordia. The bumps are caused by high humidity, predominantly wet weather, or overwatering.
Those are adventitious roots. If the plant were planted deeper they would turn into roots.

Tomatoes start out green and as they ripen a chemical process causes them to change colour. Some turn red, others orange, or white, or yellow or even purple. The leaves of the tomato plant are green because of the chlorophyll present in them.
Variegated.
THE ANSWER IS AN ARUM LILY
you are describing two different problems, the swirly white trails look lke something small is "cutting a new path" inside the leave, right? it is a small moth larvae eating the leaves. they dont do too much damage and dealing with them involves strong poisons so i recommend to just leave them be. as for the new growth, it sounds like it is nitrogen deficient, i'd recomend a dose of 20-20-20 fertilizer with added micronutrients. best of luck
White teas has caffeine. The word white is used because the tender leaves at the tip of the tea plant are picked vs the older leaves.

Pumpkin leaves could have been eaten by some kind of bug, possibly and most likely an aphid. This is probably why the leaves turned white.
