Growing in coco coir, when to start nutes?

[IslandGreenGuy]

If growing in Coco, When do I need to start the nutes? I know they have very little of there own. I'm going to try out one or two plants with it, just to see if that thread I read about it being "so much better then soil" is true. I started them from seed on Friday.

It depends on what Coco medium specifically, some have nutes while others don't really have any to speak of. Either way though don't start your nutes until the seed leaves (cotyledons) either yellow, or fall off.

ok. i'm no expert. i'm doing a new coco grow myself.

i have 3 sensi skunk seedlings in coco.

i had germed the seeds in rockwool for 1 week and the roots had just broken the surfrace of the large rockwool cubes. i believe they are 3x3 inch cubes. i transplantd to a nice fine coco soil in 1 gal pots.
.
i heard to start very light nutes early when using coco so i started quarter to half strength nutes after 2 weeks of being in the pots. so they are roughly 3 weeks old.

i have nutes to 2 plants. one plant responded badly by showing typical signs of light nute burn. yellow to burnt brown tips on the new leaf growth.

the other plant which is generally more healthy, e.g. more internodes, taller, more leaves etc... it has responded fine with no signs of nute burn at all.

so i think it is ok to start at 2-3 weeks with a say quarter strength nutes and build it up from there based on when you need to water next.

it is interesting how you get different results from different seeds even though they are all from the same batch. it's good fun choosing which of your plants has the best genetic features. 1 out of my 3 sensi skunk plants is good so i can only hope that it will be female now

yep that's a good guide. thats why i started my nutes although the leaves were only yellowing on 1 plant but i decided to give them all a feed anyway.

surprisingly, the plant with yellowing leaves actually showed signs of stress when given nutes whereas the plant that still had very green baby leaves, loved the nutes and has perfectly formed green leaves and twice as much growth as the other 2 plants.
?? i dunno. i think she's tough.

coco is a beast of its own. generally speaking, its cool to give them food after the first true leaves appear. be sure the ph is correct, coco likes it better a little lower than ususal. my food is at 5.8. thats the norm fo coco. be sure to adjust every 5 days as the food seems to be more volotile than any other used in the past......coco specific ones that is.........

grwoth is much faster. watch out for those little basterds known as fungus gnats. they LIVE in places like coco coir in potting plants!!!! THE BEST thing is to NEVER OVERWATER!!!!!!!!!!!!!!!

seriouly. use half the water you would if it were soil, then wait an entire extra day or even 2 before watering again. the coco can retain H2) and 02 like nothign else, so TAKE ADVANTAGE OF IT! if you get them, use 1 part H20@ to 4 parts H20. itll sizzle....it kills the larvae, and roots love o2.

just dont OVERWATER. IT CAN HAPPEN in coco. dont care if youve been doin it in soil for 3 decades, coco is a different animal and treat it as such.

just be sure its dry, and cover up the wet with dry matter after watering. this REALLY helps.

im no docotor, just go by trial and error. alot if stuff on here is WRONG. so be carefulllll....... most is right tho so your cool, buy alot is worng as well.....

so.....

1. use coco nutes.
2. keep lower ph than with soil
3. water less and less oten
4. cover wet with dry after watering
5. coco does not dissappeear as soil so be careful....IT STAYS LOOSE
6. watch the superb growth
7. DONT EFF up
8. and keep a clean grow room........!!!!!!!!!


my thoughts on the amazing substance.

any thoughts on re-use??


thanks all!!!!

peace and happiness.

^^ i find that its really hard to overwater coco, i drain off to waste with no tray sitting under the pot, in a 5 gal pot! big container with alot of media can hold alot of wateR.
i also am using GH 3 part flora series as my base and up to full veg strength recipe by a week in. i also supplement with cal mag because coco is naturally low in calcium, high in potassium, which further blocks the uptake of calcium...just looked at the date on the last post for this thread...im late.
