What causes a tomato to be determinate? Is it a genetic or cumulative effect (i.e. does the plant grow to a specific size or do hormones build up to a certain level, or is it something altogether different? Will suckers from a determinate plant grow out like an indeterminate sucker? Thanks
This link gives a good explanation of determinate and indeterminate.

I'm a student researching about coffee grounds. I'm from the Philippines. I would like to ask some questions. Do you use coffee grounds in planting? Do you use it on tomatoes? Do you use coffee for watering your plants or do you use it as a fertilizer? If you're using coffee grounds, where do you usually use it - in vegetable plants or in fruit bearing plants? Does it help your plants grow faster or no? Is it effective? Does using coffee grounds increase your expenses on planting or decrease it? And, lastly, if you are using coffee grounds, what coffee do you specifically use? Please answer my questions. I will appreciate your consideration. By answering my questions, you will help me with my Investigatory Project :) I will wait. Thank you so much! I really need answers.
Here are some links that will help you with your project.

My tomato plants grew just fine and fast with healthy green leaves. After maturity and fruits after 3 months, all leaves turn yellow and then dry brown from bottom up. Is it a nutrient deficiency or a pest problem?
Tomatoes can be effected by the environment, insects and many bacterial or fungal diseases.
Do a closer examination of the leaves to help correctly diagnose.
Check watering, too much or too little can cause the yellowing leaves.
Proper draining soil to avoid any root rot is important.
A soil test can be done to help determine if the issue is nutrition based.
Use caution in fertilizing and do not use to much nitrogen.
Has this been a recurring issue? Crop rotation is very important to avoid soil born diseases.

Do I need to rip out last season's plants even if they look healthy and are still producing fruit?
No, if your lucky enough to still have producing tomato plants, by all means keep them going.
I would however plant some new tomato plants in another part of the garden to keep the tomatoes growing!
Remember crop rotation is important for continues success.
