Hello everybody,

I started an experimental hydroponic lettuce, basil and rocca project.. and im a complete ignorant on the subject.

I know for sure i am making a lot of mistakes, but kind of need help pinpointing them..

Im growing in a 30 galon container, i initially had 3 lettuces 3 basils and 3 roccas in there, but i left for vacation and came back after 20 days to find two lettuces with huge stems and small leaves, so i got rid of them

I am using a 40 watt CFL (4000 lumens), (it was kept lit for all the 20 days vacation period)

My basils are looking rounded and have a lotof ridges..one of the leaves has a black stain

Roccas discolored and showing weird stains

Lettuce showing blackened edges

Im using floragro as a nutrient

I will attach a pic of the system.. i know its a mess..

Should i start over? Or something can be done with these?
