jobes tomato spikes

for spikes in each pot

I purchased some tomato spike fertilizers yesterday at Fred Meyer. They were very cheap. The ingredients are...


• 1.3% Water Insoluble Nitrogen 
• 0.9% Urea Nitrogen
• Available Phosphate 24%
• Soluble Potash 8% 

I can tell that my plants have a huge root system, and I need to repot them. With the babies, I do not have any time to do it. What will happen to my tomato plants if I do not get them into bigger pots? The pots currently have 3 to 4 cherry tomato plants.
