yup, should have juicy tomatoes. To have better success - add a 1ml of nitrate and phosphate fertilizer and 1ml of seachem flourish once a week - you will be growing like no tomorrow!
Also, you want to keep your pH at about 6.3, slightly acidic. You can achieve this with just a little bit of vinegar. I wouldn't do more then 1/4th ml at a time.
If you need additional help with all of that, send me a pm!
