LIQUID SEAWEED For seedlings?

Realshibz1 · Apr 15, 2020

Hi, I’m open to all suggestions and opinions.

I have recently set up a indoor stealth grow with LED uv lights and have 3 plants in the seedling stage they are growing their first pair of true leaves and have not given them any Nutes other then what was in the soil.

I am a first time grower and conducted some research before starting up.

I have 2 types of fertilisers that I intend to use through the plants life.

I have liquid seaweed ( intend to use throughout veg stage)

and also Tomatoe plant food (will use for flowering)

I will attach images of both and their NPK

can you please tell me what you think about this?

how early can I use the liquid seaweed?
and can I use use Foliar to apply it

appreciate your time
many tha

if the first set of leaves aren't yellow then i wouldn't feed them anything. and i certainly wouldn't give them liquid sea weed i can see bad things happening from that. if you are using soil then use fox farms nutrients. and if you are using coco then start off with canna start and build it up to canna a and b

it's more an additon to food, not food by itself

you could almsot use the tomato food from start to finish . dont' see calcium listed though

without pictures it's hard to tell. i would start them on a weak feed and see how they go with it

The first set of leaves look very healthy and green and they have been grown in multipurpose compost

4-2-6 isn't a bad NPK for cannabis.

he or she would need to add calcium and magnesium (the mag listed on the bottle is not enough and calcium is not listed).
and not sure about the micronutrients too.

Have heard a lot of benefits of using a organic liquid seaweed

there will be a fine line when your soil runs out of nutes and you'll need to add more so they dont' starve. just keep a close eye.

oh yeah, i love my dry kelp/ humic mix. it has all kinds of great stuff. but you need a fertilizer too.

just keep watering them until the first set of leaves start to yellow. i'm talking about the cotyledon leaves of course

Yeah I appreciate that, I think it might just be a case of trial and error to be honest as it is only my first time. I may apply liquid seaweed as a very weak dosage When there are a few set of leaves then see how it goes

I wasn’t intending on using the Tomatoe feed until the root system was established properly.
so wasn’t gonna use it till maybe week 2/3

that's a good plan. you will need to make sure it has all the micro nutrients you need. and you'll need cal/mg for it too. there are 16 macro and micro nutes to grow healthy platns

Here are my blueberry haze
And pink grapefruit strain

also just wanted to point out The cotyledons leaf is like That because it stuck to the casing of the seed, it is not a burn or anything like that
But hope this helps

not to turn you off the tomato feed, but if I were you I would buy GH FloraNova Bloom. it's all you need in one bottle. and i know for sure it has all the macros and micros you need. it even has some humic acid in it. you can use it from start to finish: vegging all the way thru flower. you don't need to add anything.

if you want to try the tomato, get a bottle of GH calimagic. it's probably the best cal/mg on the market. i would try to contact the company and see if they can give you a list of everything in it especially the micros. if it doesn't have micros, you'll need to buy micro too along with the cal/mg. GH Flora Micro would be a good one.

but like i said, get the floranova. then you won't have to worry about if your nutes are good enough.

Thanks man I’m all ears, the information is invaluable
I’ll be contacting the company to check the finer details

GH MaxiBloom would work as well.
