This is a complex one as there are so many for so many different reasons.
Always use the best quality nutrients you can get hold of and follow the instructions with it. DO NOT BE TEMPTED TO OVERFEED. With over-feeding the leaves will have a tendancy to curl downwards and become dark green, brittle and glossy. If this happens flush pure water through and do not resume feeding for at least 2 weeks.
Nutrients for soil and hydroponics differ totally so please include this in your query.

ANY QUESTIONS....?

The nutrients from IONIC are designed to balance you P.H for you, great if your water supply is a bit harsh.
I know of two growrooms that are experimenting with their range and I will post up the results.

:satisfied:

excellent ,just when i was thinking i would not find the right ferts,
which brand name ferts do you use for
1# seedlings and clones?
2# veg growth?
3# flowering growth?
its so hard trying to find the right ones that you dont have to hunt for! :thumbs:

You mean it's easier to ask someone else instead
I need to know what medium you are growing in first bud.

no what i meant was its easier to ask someone who KNOWS more than me on the subject what ferts i should use ha ha !

i am using "John Innes Seed Loam based Compost" which is sterilised (4 parts) Perlite (1 part) Vermiculite(1 part) .
the fertz i have at hand if i need them is
"VITAX super phosphate" ,
"Baby Bio" (will be ideal npk for veg growth) ,
"Tomato Feed"from B&Q ,
"Roota" (for clones) and
"Miracle Gro pour and feed"
are any of these any use?
the phosphate says it is for healthy roots
should i use a weak solution of this once or twice over the first two weeks? :thumbs:  :yinyang:

Theres always something you should bear in mind and thats if your fert. can be used on edible crops, like a tomato food.

For seeds and cuttings ... I recommend using Maxicrop SEAWEED extract...promotes healthy rooting and growth and can be mixed with other nutrients throughout the season.
For vegging try ... either your baby bio ( leaves a taste) or miracle-gro (also leaves a slight taste) or try something like IONIC -for soil, designed for your particular crop.
For flowering try ... again a tomato booster will do (if NPK is high in Potassium, etc) or go with an IONIC BOOST.

I recommend IONIC to you as it balances your PH therefore making growing slightly easier for newbies.

I been using John Innes for yonks now - excellent results. Seed Compost for seeds & cuttings, then into No.3; I usually start seeds straight away on No.3. For the first 8 weeks NO FEED IS REQUIRED. Then, lightly with a bloom feed for the first 5 or 6 weeks of flowering, followed by 2 or 3 weeks clean water, et voila!
Just starting an organic superskunk as an aletrantive. It should be an interesteing experiment. Using a locally purchased organic compost (Ph perfect) and Alan Titchmarsh's Organic Bloom Feed. Reports in about 10 weeks...

High there,


I've heard good reports about Growth Technology Ionic. I use G.T. Optimum Grow & Bloom myself (HardWater version), with Canna PK13/14 as a boost for 1 week, 3 weeks before harvest.

The Optimum is a 2-part solution & the results I have achieved have been excellent - a recommended hydro nutrient.

I was going to try Canna Vega & Flores, but have heard a few bad things from Dutch growers.

They use (and swear by! ) Dutch nutrients, which are not available in the UK at the moment.


All the best,


Trichome

high trichomeuk
i dont like to correct you , but since you seem adept at it   ,  IF you mean dutch formula from advanced hydroponics ,it is available from GLASGROW

Doc:

It's not 'Dutch Formula' - if it was, I would have said, so no 'correction' needed

The nutrient I was referring to is "Ferro", and has been highly recommended by 'dutchmaster' and 'k2_k' (Overgrow.com members) from Rotterdam, Holland.

I have enquired about this nutrient in the UK and no-one has heard of it, including Growell.co.uk.


Take care & all the best,


Trichome

Can it not be ordered in from Holland ?

no probs trichome
it was your lack of detail that lead to this confusion
and for a guy who it seems detail is everything is surprising
i know what you mean now though ,

its a pity, cos ive just bought some canna terra vega/flores and pk13-14, but now ive just seen several people saying they arent so good
ah well...... better than miracle grow im guessing
does anyone know how i should start feeding with these, as the plants have just been used to miracle gro/baby bio so far. the instructions are all in dutch, but it says 25ml per 5liters... should i start at this level?
also, im on day 34 12/12..... should i use the pk13-14 yet? if not, when, and what exactly should i do with it?

thanks

High there,

You'll do well with the Canna nutes: the Dutch growers who said that have never been backed-up by anyone else, so don't worry - I was wondering if anyone else had heard this.

I use PK13/14, and have recently been advised to try a new regime, which was based on his extensive experience ('peteruk' at Overgrow) - use PK13/14 for the last 4-5 weeks of flowering at 75% of recommended dose (i.e. 1.125ml per litre, instead of 1.5ml per litre).


All the best,

Trichome

if you are using rockwool as your medium then this link will be of great help to you as it is aimed at canna terra vega and flores users
growing schedule for rockwool and canna vega and flores

hope this helps

sorry trichome ,had no experience with pk13-14 as i have mainly used growth technology's nutrients (dont know why ,i guess i just stick with what i know   ,goto be more adventurous )

thanks for the help
in fact, i was just talking to peteruk about that 13-14 myself
unfortunately im not sure whether to start doing it yet, as im slightly worried ive over ferted...... would leaves curling up at the edges on some plants suggest this? i leeched them well with plain water a few days ago, and now i dont know whether to do the same thing again or move back to nutes...... also, i suppose it could be pH, as ive never bothered to monitor this...... im growing in a soil with a bit of vermiculite and perlite

peace

Hi all,
Newbie question here. I am growing in 1/2 potting soil 1/2 perlite. I have been feeding my plants with some 7-7-7 plant food through vegitative growth. I have been trying to find bloom ferts everywhere but have not managed to. I have instead bought some plant food that is 14-10-27 but I think I have made a mistake. High phosphorous not potassium is needed for flowering. Will this food be useful for flowering? If not is there any shops that I can buy bloom ferts from?

Cheers
Bern

why dont you buy some phosphorous from Homebase (i cant remember the name of it but i am sure there is a phosphorous equivalent to potash)
i will do a big of digging  and see if i can find the name
unfortunaltely the hombase site is down just now so i will post it later
peace

Curled up leave edges could well mean over-ferting, AurorA.
9 times out of 10, if you think you've over-ferted then you probably have...you have to trust your instincts...only you know how much feed you added.
pH monitoring is essential in growing good quality marijuana...especially with soil as the medium tends to stay dankish. If your pH is too high then not only will it lock up trace nutrients but will also confuse when diagnosing deficiencies.

Start with using 1/4 strength nute mixes...IE if it says 10ml per litre...use 2.5ml....use this mix until a week before flowering. Then switch to one watering of a full strength mix. For the next mix, use a half strength flower mix for one month, followed by a 1/4 strength mix and any added boost. Stop using the nute mixes two weeks before harvest and feed with plain pH balanced water with a touch of boost to finish.

*as you may have toxified your medium, I would advise you to start this regime with a totally new medium and as you are soil, I recommend..John Innes No.3 70%, vermic 20%, perlite 10%
