Can you over-water Coco?

Y

Fizzy...look to your tap water for your problem. A .5 EC means you have got terrible water that probably contains a lot of salts that the plants cannot process...hence your salt buildup problem. On top of that you cannot add enough plant nutes due to that high of EC water which means you are going to constantly fight deficiencies.

With good water one should be able to water as much as 5 times a day without salt buildup...at least for a normal veg/flower schedule. Keeping long term mothers in coco may require some flushing to prevent long term salt buildup.

Anyways...clean that water up and I bet you a whole lot of your problems (and questions) go away.

Yeah I'm at 3 times a day with some smaller plants. I'm probably wasting water, but with a scheduled water you can't really overwater.

If I hooked up a feeder and ran it 24/7 then that might kill it.

Quick question on EC in coco, If my tap water is 0.25 EC and I want 1.0EC do I subract the initial tap water and give a full 1.0EC of nutrients? so it would be 1.25 EC...?

chr0csxs no you dont extract it you include it..thats why having near R/O lets you have better nute capacity....afaik...

Thanks guys.. i think my water is really hard (and salty) but not much i can do about it.. its 0.5ec out the tap..sometimes 0.4ec..(at a pH of 7.5,always!) I use canna nitric acid ph down...

Cheers

i was watering every 24 hrs for veg and the first week or so of flower but ive started waterign every 36-48 hrs and things are much better imo. When i water i water heavily and by the time i'm about to water again the pots are very light but i have had no issue of salt accumulation.

the water water mentality is like the put a 1000hps over your seedlings mentality, sure u can do it, but whats the point? the plant cant grow anyfaster then with a few cfls as it has no fans yet or roots to metabolize the excess photons, much like watering like hell a young plant in coco, sure it might survive but for what, to waste water? to fear imaginary salt build up? ive found that watering pretty good with a little run off and then letting them rest for a day or two is the best for me, any more then that and plants complain. everyone should learn there own parameters, as temps make a big diff, one size fits not all.

a good rule of thumb is to take a strong food, a medium light food, and plain water in your room, as the leaves get to dark or claw then u have the proper strenght food to feed them right their, we all get lazy but not all plants do the same things, some need plain water once or twice a week, some dont. again no one size fits all, u actaullly have to learn your own room.

ok i read most of the posts in this thread.

i have 5-6" plants in 5 gal pots using 90/10 coco/vermiculit

i started the plants in 8oz cups

im currently watering everyday with about 500ml of water each which gives me 10-30% runoff

they look ok, but after reading about the whole "its very easy to over water if the plants haven't spread the roots well throughout the pot- ie small plants in a big pot" so this has got me worried


maybe water every second day?

any help?

And still relevant


Indeed.

Its those absolutes that growers take for granted.

I grow low watts micro in 16 ounce hempy cups,
and with no climate control. I watered everyday,
cold or hot and slowly watched my plants slip into
slow growth and pest prone mode.

I now water every other day and am now aware that
coco can be over watered, in certain conditions.

Revive an old tread, yup, it matters, lol

Hempy cups? Sounds cool. How micro do you grow? Im thinking about doing a little box myself, why not? Minimal climate control sounds right, as in its got a door and i switch the lights.

This is still being debated -
You can definitely water to often and cause your plants to be stated of oxygen - this usually Happens when the roots are small - but even when doing a wet dry cycle to establish roots you never want to let the coco get really dry. Just to the pint where the pot is light.
Letting coco dry out causes a spike in ec level8!

It depends - when the ec spikes it will drop the ph and could lead to lockout - or start to burn root hairs and cause overfert sysmtoms - but I am no expert so maybe some one else can chime in -

Coupled with the over water of coco debate is the final flush deal
of flushing a low EC or just plain water, lol

I flush for a few days at .4 EC +/-.
