new to hydro

I started tomato plants in an Aerogarden until they maxed out in height. Transferred to a floating raft in 3 gal.buckets using miracle grow tomato plant food as the nutrient solution. 1 Tsp/gal + 1/4 tsp Epson salt. Also added a drip system to each plant.

The leaf edges turned dry and brown and plants are not growing. The stems look healthy. They have been in this system about 2 weeks with no change.

Lighting is a double 4' fluorescent fixture with grow lights about 10" above plants 16 hrs/day + some natural light.

Plants are indoors at constant 70 degrees F and solution is circulating constantly.

Any ideas why this happened and suggestions appreciated.

Hi Tom,

Boy am I confused by your letter! Some points that might be problematic:

1. What hydroponics method are you using? You wrote "floating raft in 3 gal.buckets. Also added a drip system to each plant". Not sure I understand your setup, can you supply a picture?

2. Nutrition: "miracle grow tomato plant food as the nutrient solution. 1 Tsp/gal + 1/4 tsp Epson salt"

Tom, This is not a balanced, provide-everything-needed hydroponic solution.

3. Lighting: "Lighting is a double 4' fluorescent fixture with grow lights about 10" above plants.

As we explain in the website, fluorescent lighting is not sufficient to grow flowering or fruiting plants like tomatoes.

I would like to direct you to the following pages for more information:

Good luck to you, Tom, and hope this helps!
