question on nutrients and feeding (miracle gro)

i heard different things about miracle gro (good and bad). i found some miracle gro rose food around the house. The NPK ratio is 9-18-9. I'm reading Greg Green's Marijuana Bible and it says for flowering, the plant should be fed nutes w/ a higher P value than N and K.

For the veg period, the "bible" says to use a fert w/ a higher N ratio than P and K, so I'm going with Grow More's Soil Acidifier which has a npk of 30-10-10.

so i was just wondering if these are ok to use for feeding. i'm asking because i don't want to spend anymore than i need to. all those nutes i mentioned in this post were given to me at no cost. however, i am willing to buy more things, but in a cost efficient manner since i think i'll be needing to buy more ferts for the secondary and micronutrients. recommendations are welcome and wanted!

I am going to assume you are growing in a WalMart type potting mix and using tap water. If so, those will serve you fine for your first grow. You will need to be careful about burning the plants, especially early on. Just go super light, like 1/8th the recommended dose when you start feeding and you should be ok.

You could easily drop a hundred dollars at the hydro store on fancy nutes you don't really need at this point, but for your first grow I think these will serve you fine.

Just remember, the absolute most important factor to increased yields is light. $1000 spent on nutes will have a miniscule effect on yield as compared to a $100 light upgrade.

I use standard miracle grow for vegging.
None for the first 2 weeks and then start with a 1/4 dose every time you feed/water then up it a little week by week but never go full strength with it as its high in npk. I only go as far as about 3/4 strength near the end of veg. It works exellent and promotes rapid growth.

This all depends upon how "hot" your soil is to begin with. The soil I use does not require nutes at all through 3/4's my veg cycle. Wisco is correct, if you dump 100bucks on some nutes you might be alot happier, Wisco; also...not just light, do not forget that environment! :tiphat: Temps/humidity light are all factors that make up more than 1/2 my yield. Nutrients and grower error, or lack there of (fingers crossed everyday) dictates the rest in my life experience with cannabis.

btw, this is regarding an outdoor grow of a clone of trainwreck. here's the lowdown. my friend received 2 free clones of trainwreck at a dispensary. one of the clones was transplanted into the same pot as a indoor flowering mango kush plant. this obviously stunted its growth (which was evident by comparing it to the second clone). for 10 days it was left in that shared pot in a growing tent on a 12/12 cycle. buds and pistils (i think, those little hairs) started growing by the time he transferred it into its own pot w/ potting soil. each NPK value of the potting soil was less than 1%, but i can't remember exactly. if it's important, i'll go re-look it up. the problem was, the soil was from an unopened (but it wasn't perfectly sealed) potting soil bag left outdoors. spiders would crawl when you lifted the bag up, so he concluded it wasn't suitable for indoor growing.

after 4 days of the clone being in its own pot and still indoors, the plant was transferred to his backyard. today marks the 3rd day it has been outdoors. the plant has not been fed since transferring outdoors, and it hasn't been watered since the bottom soil is moist. we're not sure when to feed because i know overfeeding is bad, and so is overwatering. i also know that you should use less (from 50%-25%) strength than label directions. the bottom fan leaves are turning yellow, and only 2 leaves have some weird brown color on the very point of it. are these problems due to the stress from environment change, or are these nute problems? here is a pic

When your first starting out don't let all the *BLING BLING* get in your head, watch your plants they will tell you when they need something and keep a journal for personal reference and you will do fine.
