Depends if you are growing indoors or outdoors and the equipment useed if indoors.





I usually don't modify the nutrients until the 7 leave palms appear but I do it outdoors and start in July ending in Oct.





Sound like you are growing indoors, I'm not sure if plants that age will produce.
Why are you spending money on different foods for plants? All you need is good compost/soil and occasional additions of some fresh compost and they'll do fine unless they are very specialist exotics. If that's the case you should have got growing instructions beforehand.
