What are your plans for growing them on? Planted outside to a garden would be great as they aren't going to be able to remain in that size container for much longer. If you are planning to keep them in containers then you'll need much bigger ones - 7 to 10 gallons/liters and a much better potting mix.

Organic fertilizers are great for a garden but don't do much for plants in containers since there is little to no bacteria present to pre-digest them so the plants can use the nutrients.

Did you fill those containers with regular dirt from the ground?

Maybe it's just me, but those plants look a little leggy. You should probably give them a bit more light.

They look good. Suggest getting them in the ground as soon as possible, and plant them a bit deeper than they are now.

Thanks everyone. Already bought a potting mix ang will be transplanting these to bigger pots tonight. A friend of mine gave me a packet of fertilizer. Will this be good for the plants?

That fertilizer is comparable to Miracle-Gro here and is good to use as a typical soluble fertilizer as you shall, although it says foliar. As already mentioned, it is not enough. You need one of those bags per plant at the very minimum. Dosage/frequency for tomatoes is same as Miracle Gro + you must use hard water or another CalMag source if the potting mix has not been limed.

Cheers
