Hah yes, i know lillys done quite a bit of growing. She makes me proud.

Either way im happy to be helpful, i have alot of respect for the mods / people on these boards who go out of their way to help people so i try to do the same. Makes me feel like im giving something back, plus if i can help someone else learn from my mistakes so they dont have to make them thats a good thing.

Heres what i do for feeding, its a generally simple practice and ive only burnt my plant once (and it was very very very minor). For vegging i use Miracle Grow (forget the name but it comes in a little yellow bottle, looks alot like a mini laundry detergent bottle) but anything decently high in nitrogen and potassium will work. Read the instructions on the box then cut the amount per gallon / litre they give in half (or if you wanna be extra safe, which i suggest you do your first feed since all strains behave differently cut it by 75%). I normally put myself on a regimine that starts after the last flush, i give my plant a good flush then the last bit of water i flush her with is a 25% nute solution so she's got something to eat. A little bit of Hydrogen Peroxide helps to get some air to your poor drowned roots is you want to put some of that in with the nute solution. leave her alone for 5 days or so (she'll want to get nice and dry after that flush) then i water her twice, feed with a 50% solution and just use plain water till the next flush (repeat).

So in your situation id just start feeding maybe once every two weeks with a 25 to 50% solution and see how your plant handles it, if they're lovin it start feeding a bit more often but the key is to move up very slowly as it alot easier (and less stressful) to just add a little more fert then it is to burn the plant and have to flush out your soil all over again.

When you get into flowering do basically the same put replace the miracle grow with a fert thats lower in N, higher in P, and about the same in K. I use this stuff i found at lowes thats made for orchids, its got something along the lines of 11-35-15, along with all the micronutes the plant needs and its been doin great for me so far. Oh also get some molasses and feed that to the plant as well (about a tbsp per gallon) when you start flowering she'll thank you for the extra sugar / carbs by growing much denser buds.

Basically feeding is kinda a learn as you go thing, everyone develops their own methods and such. The key in my opinion is to start with baby steps and work your way up, because like i said earlier, hell of alot easier to put more in then it is to take stuff out.
