Light green coating??

[itisme]

I am getting a light green substance over the top of my coco mix. What is this?

 

[robbiedublu]

Some kind of mold? What is your coco mix exactly?

 

[itisme]

Boticare cocogrow....Mold is what I was thinking??? I haven't had good ventilation but I got that done yesterday! Maybe that?

Could be slight salt build up or chloramine. Do you use tap water?

Well water.....

Im not sure about well water. Theres alot of threads about salt build up and chloramine on here dude. Have a browse about. Check out the hand watering coco thread on the stickys aswell. Everything you need to know is in there i guarantee it. Its a long read but very informative and interesting. Hope this helps.

Thanks very much THEPIKE! I will do it......

sounds like algae,caused by the medium being exposed to light,i don't know how you would go about covering it up tho....its pretty common in hydro systems.


i've never grown with coco,so i'm just going by what the description sounds like


good luck

This may well be the case. Im a bit of a newbie myself. I was having a similar problem but mine was being caused by my water. Iv got it sorted now.

At first i thought it was salt build up but after a few flushes i was still having the same problem. Then i read it could be calcium carbonate. Suposedly when hard water is treated (pH down) the calcium bicarbonate precipitates out as calcium carbonate chalk. Its not meant to be that bad for the plant but it can react with fresh feed and hold some chemicals back. As it's a physical deposit you have to scrape it off. As my nutrients buffer my PH perfectly i dont hav to use PH down anymore and i havnt had a problem since.

Thanks so much for the help though.
