hmm.. yeh get nutrients... those things need Nitrogen!

(this is in-case you didnt know)
Nutrients are measured in N-P-K values, N stands for nitrogen, P stands for phospherous and K stands for Potassium, these are the three major elements in nutrients.

Nitrogen promotes healthy green leaves and good vegetative growth,

Phospherous promotes good root systems and strong plants

and Potassium promotes fruit/flower production, and stops plants drying out quickly.

There are many more minerals and micro-nutrients that can help a plant grow, and in order to keep a healthy plant indoors, you must learn to understand these as best you can, in addition to nutrients micro-organisms play a big part in healthy growth, micro-organisms are basically friendly bacteria, they help a plant take in what it needs, and are pretty important, the best thing to do is read, read, read, and then apply everything you learn to your grow.

your luck so far has been off, but like the old saying goes, 'youve gotta crack a few eggs to make an omlette', so good luck for your grow...
