Hello Everybody,

First time grower over here. Have done a lot of research before I Start with my first indoor grow, my question is about NPK nutrients

1. During the first two weeks after the seed germinates, I plan on using a 20-20-20 NPK Nutrient
2. During the Vegging phase, I have found something which is 28-11-14
3. During Flowering, I have found something which is 10-25-25
4. I have also found a product for supplimenting the micro nutrient

Does the above sound right? Is this what I should be doing?

No, it is NOT right.
Don't give nutes for the first 2 weeks like you are planning, that is an easy way to burn and kill your seedlings.

If you use soil, not 'dirt' (shit from the yard) you should not need anything but water for at least the first 2, most likely a little more than 3 weeks.
However, the 20-20-20 you have should be ok. for veg, just ease into it, but in flowering, I would not give N until/ or unless your plant says she wants some.
Excessive N in flowering can and will stunt/ slow the flowering (buds).

I will use a soilless potting mix ...

it mostly contains - vermiculite, perilite ,cocopeat, sufficient organic manure

I get your point about absolutely nothing for the first two weeks. Thanks for this tip

So you recommend 20-20-20 for veg,

No nitrogen at all in flowering. what about phosphorus and potassium during flowering? cant find anything with just P and K in them....

you'll still need nitrogen in flower.

Most "bloom" foods will result in premature leaf drop. You want enough N to keep your leaves intact through flower.

Thats what I thought too, that some nitrogen and more of P and K are needed for flowering period, which is the reason I picked 8-25-25. this is an inorganic water soluble fertilizer which can be fed through soil. it is basically being sold as a flowering time booster.

There is another option of a slightly milder fertilizer, that one is 5:10:18, i guess i could consider that too if some experienced people recommend that over the 8-25-25

Also, still confused if I should go with 20-10-15 for veg period or 20:20:20? Because I was under the impression that a growing plant needs more of nitrogen and not so much of P and K. If that is correct, then would it not make more sense to go with 20-10-15? Or maybe what I read was incorrect information...can someone please clarify this for me?

Thank you all kind people for helping me out.

what up 1st off scrap that 20-20 junk.(yuc man).get some hygrozyme if ur n soil get fox farm ocean forest,for the 1st 2 wks after plantin h2o &zymes only nuuts r n soil.decide btwn organic vs chemicals synthetic ferts....organic --iguana juice by advanced nutrients,pure blend pro by botanicare,bio thrive(veganics)GO Box by general hydroponics organic line all work perfect o guessin or confusion.syn-- floranova by gh,oneness by humbolt nutrients is a stand alone fert.meanin its 4 grwth & blm READ MORE VISIT GROW STORE & ASK QUESTIONS ---TRIAL& ERROR K.I.S.S. keep it simple stupid

^^wtf man...? You told him NOT to use a balanced fert then just named like the 6 most popular hydro companies and recommended any or all of them with no basis for one or the other, essentially just listing them like a catalog... Then sent the guy to see a salesman for better advice? Asshole...


OP, firstly even in soilless you won't need to add any nutrients for the first week or two. Plants store energy in their seeds.

Next, I'd say the 28-11-14 could be a little extreme(that's almost 3x the N as P), maybe mix it with the 20-20-20 to balance it a little because 48-31-34 isn't so drastic(and similar to the 6-4-4 I personally use and like in soil). It's also going to come down to micros and sources, all equal ratios aren't necessarily equal nutrients.

For flower, IMO you'll need more N depending on source. Try to get it closer to the amount of PK, you still want a somewhat balanced fert. Anyone telling you not to have N throughout flower has no idea what they're saying or why. That leaves you only using a bloom booster throughout flower, SUCH a bad idea. It doesn't hinder bud growth, a quick flip through a botany book will tell you exactly what mechanisms the plant will be unable to complete if you lack ANY micronutrient, let alone possibly THE most important macronutrient.

These will both work. Just remember that less is more. Feeding excessive fertilizer isn't going to make your plants grow faster, it will burn them. Think of the process as facilitating the plants growth, and not trying to make it grow.

Don't waste your money on hygrozyme. To be honest you really don't even need to visit a grow shop. You can grow fine bud with a 20-20-20 for veg and a 10-30-20 for flower. Just think of it as growing any other plant in your garden. Weed isn't special. If you do want to buy some kind of special additive, try liquid kelp. Stuff is full of vitamins and hormones and will make your plants super healthy.

Happy growing

thank you mate, good advise. I have a water soluble thing for micro nutrients as well, which I will be using probably once every 3 weeks to a month.

Mate, I cannot find any weed specific nutrients where I am located, I will have to rely on general garden nutes, which I am pretty sure will work.
More Nitrogen during growing, more P and K during flowering, with occassional dose of micro nutes, this is what I plan to do. Of course I will be keeping a keen eye for signs of nute burn, and of course I Will ease into it, with small doses to begin with.

Exciting times, my lights are sorted, soil is sorted, seeds are sorted, and as far as I can tell, my knowledge of nutes is also now sorted. I just have to make it all come together now!!!!

I also have one other small question, for someone who has tried both organic and inorganic nutes - does using inorganic (chemical) based nutes have any effect on the taste?

kingfisher u can take whoeva advice.i jus joyd last nite playin on my phone.so chk dude pics out &dude growin hydro with potassium nitrate that shit causes impotence unless u counter wit some organics To me it looks like is jus tryin bullshit :keep ur N P K simple that high ratio can fuc yo crop up especially if ur strain is fert sensitive.dnt no where locale is...this loco is n kushtown L.A. (CRENSHAW)homeboy i deal with OG rite now i doin Abusive &kinglouie did mk ultra bubba &pk last year,so when post u can peep and decide urself.i get paid 4 this legally.i was told by my white hippy homie too:b @peace,love & talk to ur plants they feel ur vibe KISS

PSA: This guy does not know what he is talking about. potassium nitrate causes impotence? It's in almost every synthetic base nutrient. Counter with some organics? LOL

God people should be able to pass an aptitude test before making an account...

Got it guys, thanks a lot for your help!! Now only if someone experienced with MH and HPSV lamps clarify a few things, I'm good to start...anybody??

What do you need clarified?

typically people run MH for veg and HPS for flower.

HPS gives more lumens and might yield a bit more overall.
MH will give shorter node spacing and more heat.

You can run either one the whole way through, though.

I will run MH for Veg Cycle, and HPS for Flowering,

Just need to know, what color temprature should I chose for my MH and HPS lamps?

personaly I feel the color temp is partly hype if you notice when the temps are modified much from base on either bulb the lumens go way down. dont buy off brand i prefer us bulbs eiko sylvania ect eye does make a great hps though
