Nutrient Solution Question

10 years ago

Hi guys,

I have just recently started my first hydroponics grow, and I have some questions about the nutrient solutions I am using.

I am running 2 Rubbermaid Roughneck bins turned into DWC systems. One system has seedling cucumber and roma tomato plants, while the other has lettuce and broccoli. I am using GH Flora Series nutrients.

In the first bin with the seedling cucumbers and tomatoes, I used the general purpose seedling formula (1/4 tsp of each solution per gallon). These plants are looking a little yellow. Does this mean they are lacking nutrients? I took some readings today, and the solution is around 6.3 pH and around 350 ppm.

The broccoli seems to be growing okay, but seems a little yellow as well. For this solution I used the full strength general purpose mixture (1tsp of each bottle per gallon). My readings for this solution are 6.5 pH and around 600 ppm.

Any help is greatly appreciated!
