I am raising tomatoes in containers, in a greenhouse.
I have both determinate and indeterminate plants.
After much research, I cut down on the amount of nitrogen and added Epsom salts to the soil. The plants are green, have a lot of flowers and in most cases, are setting fruit. However, the plants look scrawny. Some of them don't have a lot of foliage.
Should I add nitrogen?
We have had record heat here lately (7000 ft. NE Ariz) and have been struggling to keep the temperature under 90, using the exhaust fan and misters.
It is now cooling off and getting into it's normal temp. range for here.
Is heat the issue, not enough nitrogen or water?
Thanks for any advice!
