coco coir..... problems

hright guys, its my fourth op. never been too serious really. a few here and there but ive been lucky enough never to have any problems and always had a good harvest..

any way, between my last and current grow i read up and decided to change to coco for my plants.

iive kept every other factor the same as before as i did with my soil ops. pot size, nutes, light, etc

i did have four seedlings. 2x WW and 2x BLZ bud. one of the BLZ have already crisped up and died. the other 3 are now seeming to be doing the same.

sooo.. now for the question. i have used 100% coco. is this incorrect to begin with? maybe mix in with soil? 50/50?

i have a slight feeling i may of over watered too, but then i left it till it was dry again almost.... could this of killed my babies?

i think im gonna start again with some new seeds so wanna make sure its right this time.

thanks
PJ

Hey there papajow, sorry about your loss.

I am currently flowering 5, a mother, and a seedling in 100% coco. Coir is actually hydro so you can't really over water. I feed everyday or every otherday depending on my schedule. I drain to waste and shop-vac the extra. I use the House & Garden Cocos A and B with their line of additives plus Snow Storm.

I've heard in 100% coir there can be problems with keeping the roots aerated if coir is on a drip system, so I just hand water in the morning 2-3 gal for all five in flower.

I think what happened was you let it get too dry and/or your nutes. Coco seems to like coco spec nutes. I guess coco screws with calcium or some stuff. This is my first crop in coir and i have to say it's phenominal so far. (Knock on wood)

Hope this helps Good Luck!

coco can hold salt in so normally people use coir specific nutes, also ive always used 60 coir 40 perlite and watered about every other day

only now im dwc so dont use coir anymore but i really liked it kind of a happy medium inbetween hydro and soil even though it is hydro
