OMG, I really don't even know where to start with this, um well first off since its obvious you don't have any experience growing cannabis I highly suggest you get a grow guide, I recommend "
Growing Elite Marijuana" by Ryan Riley
(-->CLICK HERE<--), however there are many other guides to choose from, just Google cannabis grow guide, although this forum is very helpful and has a lot of useful information you will get a lot more "Factual" knowledge out of a grow guide, also, if English is not your primary language I recommend getting a guide in the language your most fluent, comprehension is key as there are a lot of factors to consider, especially when growing indoors, if you can't find a guide in your language you could always just get a digital version and use Google Translate. Now if this is an option for you I highly recommend you get a 250W-400W HID (HPS/MH) ballast and reflector, preferably an air cooled hood so you can hook up ducting and inline fan, HID lights produce a lot of heat that needs to be ventilated from the grow space. Now as far as the feeding/watering goes what you posted doesn't sound right at all, you only want to water/feed when the soil is almost completely dry so the roots dig deep in search of water, once the pots/soil is almost completely dry weigh the pots and in the future when they get that light you know its time to water. As for feeding just follow the instructions on the bottles to the letter, however start with 1/4 the recommended dose, see how they respond and then increase as needed, remember less is more, nute burn will stress the plants more that a slight deficiency. Well I hope this helps and I wish you the best of luck.
