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.
