I'm new to hydro, asked for a tower for Christmas to dip my feet in till I make a DIY setup when I have more space etc.
I used distilled water
I went to my local hydro asking what is best media to grow in for hydro tower and he gave me canna root plugs. My seedlings were doing great till I actually put them in the tower.
The cucumber leaves got white spots ontop and brown scars underneath. Tomatoes started to brown on edge and droop completely. The store gave me & pure blend pro grow & pro bloom I used around 10 ml total 5ml of each for Reservoir.
Did I shock my plants because of the vauge instructions or is it because I used root plug instead of rockwool binding the roots up and causing root rot and mildew?

Not sure but it looks like you’re not using calmag, even though the nutrients specify that if using reverse osmosis water you should use it. Could be the case here.
From my novice perspective, white spots on leaves/ decay between veins in leaves tends to be a lack of magnesium or calcium.
