hi, this is my 1st marijuana plant and im doing it pretty simple. 1 plant, outdoors, medium growth soil and im on my 3rd week. its starting to look/smell pretty good and i can tell its a female. i was wondering if miracle-gro would be a good idea or if there were any other nutrients i could get from home depot, a smoke shop or some place local. i dont have a credit card to purchase any of the good stuff online ideal for pot growing such as advanced nutrients. here are some pictures...





any help at all would be much appreciated... also notice the bottom leaf is a little torn, is this a problem?

looks good, you wont know female or male until flowering unless it preflowers
oh, alright thanks for that info... i had one failed attempt at growing a plant early in the season which i thought was a male. after 1 week it got to be about 6 inches tall but i guess it was just looking for sun since i had it in a garden window. does anyone know what a good time would be to add miracle-gro or if miracle grow is a good idea at all?

The seedling leaves will yellow and drop soon after the plant starts developing 'true' (3 or more blades) leaves. The first 'true leaves' are often a little deformed. Don't sweat it.

All good so far.

Contrary to popular belief, Miracle Gro will work for cannabis. It's not the very best, but if you can't get anything else, it'll do. Use the version for vegetables and use about 1/2 the amount suggested for outdoor plants.

As you will of course know from your basic reading on cannabis plant biology, you'll want to use a fert that has a high amount of nitrogen (N) in the NPK ratio. A suitable vegging fert might be 20-10-10, meaning 20% nitrogen, 10% phosphorus and 10% potassium. When flowering, you'll want a fert with more P, so 10-20-10 or an equivalent ratio would be most suitable.

Most ferts for flowering plants will do if the ratios are not excessive. I've seen Schultz 10-50-10 cause lots of problems- just too much P in that ratio.

Someone will surely go look up the ratio limits for cannabis- I'm short on time at this instant.

I am experimenting with some fert close to that ratio 10-52-10 it is expert gardener bloom burster or something like that I am taking it very easy with it though thus far no probs... didnt want to hijack this thread I do have an opinion on miracle-gro I have used it and many friends use it it is just fine and as al said mix it at most half of the recomended mix . I have never had a great crop but this is due to lighting and rookie mistakes never have i had any nute issues with miracle-gro

Taking it easy might be the trick. Most field anecdotes I got on Schultz 10-50-10 while I was mentoring on Overgrow were from relatively new growers who could well have had other probs.

My own experience with 10-50-10 was tip burn at the mfr's recommended concentration. Halving their suggested dosage probably would have sorted it out, but I moved on to hydro and no longer had need to play around much more with the stuff.

I used Shultz 10-50-10 for a little while as well. low dose med dose and high, hard to find the right strenght, prob due to veg fert ratios time used strength etc. It seemed with 10-50-10 a light mix would show N def (yellowing) and anything close to regular or strong would burn tips. + 101 other variables that I don't all know fully lol.

alright, thanks for all the help but how long should i wait to start adding miracle-gro and how often should i apply?

also, i heard that tying a string around the bottom of the stock and attaching a stake will help strengthen the plant. every day move the stake about 1 inch in a circle around it applying tension and youll have more buds come harvest time... is this true?

When your plants have their 3rd set of 'true leaves' is a pretty good time. Start with 1/4 the recommended amount of fert for "outdoor plants." Fertilise only once weekly- no more often. Plain water the rest of the time.

Remember, these are plants- more isn't better. There's too little, just right and dead.

Total wives' tale crap. Throw that one in the 'hooey' bin.

An oscillating fan blowing on the plant is necessary to build stem strength so it will stand up under the weight of buds later on (and suppress powdery mildew), but this will do nothing to specifically increase yield, other than keep the plant healthy.

That concurs with other reports I got. Apparently, 1N:5P is too far out of whack for cannabis. Pretty good for African violets, though. I've seen 10-60-10 for those.

Just a further note; this idea falls close to the 'stressing' category. Old school (1960s-70s) 'wisdom' was that all manner of plant damage or abuse from kinking stems to putting a nail through the stem was reputed to increase yield, potency or both. Truth is, this nonsense just gives you kinked stems with holes in them. Plant abuse is ALWAYS bad for yield and potency.

You're looking to replicate ideal conditions as they would be in nature; sunny days every day that are of the length suiting the growth mode you want, a gentle breeze to circulate fresh CO2 and build strong stems and adequate food & water from go to whoa. Healthy plants make more buds with more resin than abused plants, every single time.
