One months experiment on Cucumber greenhouse by using a regular fertilizer for growing

We made an experiment and used 2 different type of fertilizer on 2 different cucumber’s greenhouses. This first video is for using a regular fertilizer not ours.
The gardener is talking about the color of the leaves which became yellow and also the quality of the yields which are not acceptable for him. There are so many pests on the products too, and all of them happened by using some regular fertilizer.
