Nutrient defficiencies pics

[elriraikn]

Here are some pics of a some of my plants. The first one has some brownish marks between the veins and curling of the leaves. The next one has white stuff growing near the ends of the leaves. and this other one, its hard to tell in the picture, is kind of wilted on the top and deformed. They are also all displaying purple stems when they were first watered tap water was used, which was later discovered to be high in sodium. the soil was flushed and bottled water is now being used. they have been foliar fed the past two days and new leaf growth is starting to look healthier. do you think these damaged leaves will recover? do you think the plants will be ok? any recommendations?

yeah bro the plants will be fine but you need to start adding nitrogen and stop foliar feeding them for a couple days. also make sure the light is not to close to tthe plant
