Green mold? or something ontop of soil. PLEASE HELP

[sednal]

UPDATED Question

Our camera is currently not working or we would have a picture for you but we are using the exact soil mix below, along with the full bonticare line for soil and on the schedule of feed water water feed. *side note this is our first full indoor organic grow*. They've only had 1 feeding of Pro Veg and Liquid Karma followed by 1 watering.

We germ'd 4 feminized seeds, placed them in the soil mix, gave them their first nute, watered 3 days later. Just checked on them theyr sprouted and looking good but the severly disturbing thing is a green buildup has occured on the top layer of soil oon 2 of the containers. It does not completly cover the top but it looks like it could if let unchecked*. 1 of the plants sprouted before the rest and looks amazing and has no green buildup on the soil. The perlite is taited abit yellow from the nute/water mix don't know if that has anything to do with it.

I know it is very hard to diagnose a problem without a picture, but any help would be fantastic. The color of the green mold or buildup or whatever the hell it is, is abit lighter then a traditional pine green.


LC's Soiless Mix #2:
6 parts Pro Mix BX
2 parts perlite
2 parts earthworm castings (Rising mist Organics, KS)
Powdered (NOT PELLETIZED) dolomite lime @ 2 tablespoons per gallon or 1 cup per cubic foot of the soiless mix.

could you be overwatering? creating algae? I got it earlier (using perlite/vermicultie mix) and backed off of the feedings and it's gone away and the plants still look great.

You know what we did give them a little extra water, thinking it couldn't hurt. IT DEFINTLY looks like algea. Went out of town last night and locked up all my doors and accidently closed the vent to this veg chamber so the humidity was high in there overnight aswell. I dont know if i mentioned this happened in 24 hours. Theyr due for a pure watering next but i am definetly holding off till this stuff is gone. btw the plants are still very healthy.

This being our first organic grow, it is definetly a stupid question but do i have to keep the soil semi moist to keep my microherd alive?

I have found in organics this happens sometimes when you get too much water, too much humidity, food, and light on the surface of the medium. I've also found that the micro herd will kill this stuff off if you just bring conditions back to normal and have a good mix of beneficials.

^^^^^Agreed, it happens on my coco when that gets wet spots, it's just algae it won't harm them ..... keeping them wet will harm them tho'

 

[boo]

let 'em dry out a bit or your gonna be dealing with rot...let 'em dry to the point of being just moist before rewatering...

 

[sednal]

awesome thankyou everyone youve made us feel alot better, now to enjoy some of the last batch

Does it look like this? I have this stuff for a while and my plant has pale green areas and retarded growth. Don't know if its related or not.

we can control the watering, humidity, and food but theyr on a 24/7 light schedule in sprout/veg. Should i change the light cycle to kill this off or continue to well ventilate and let my little micro herd kill em off.

exactly like that but abit worse(not to much though)

 

[maryjohn]

just ignore it. bit of algae won't hurt anything.

also take the advice about not over watering.

 

[sednal]

*update* Closely looking at the algea i noticed a little mold(white) aswell on top of the soil, it was brushed away easly with my hand but we are wondering if any treatment is needed for this or will it cure up like the algea with what was discussed above.

 

[JackTheGrower]

Tell me a little about your water.

Interesting..

 

[maryjohn]

just ignore it. and stop stressing. You are growing organic now. If you don't have any signs of pests or symptoms visible in your plant, let it all slide. enjoy the show.

Neem oil drench once in a while preventive, and you should be fine until you get lazy and the bugs figure it out.

Might be a simple as too much nitrates. I wonder where the water comes from.

Also have you used non organic fertilizers?

Interesting because it has to be more than a little wet.. Has to not be draining (in my mind).

 

[JackTheGrower]

Just an FYI Nitrates in the water can be unhealthy to people.

Some wells have this.. So that's all I have to say on this. Thought to send a heads up!

Looks like iron def.

 

[ItsAllOver]

I agree, let it go. The only thing is that a thick algae layer can choke off oxygen to the root system, but I bet it's not that bad. That is mostly only seen in Rockwool situations, and even there, it's probably rarely a real issue.

Overwatering and high humidity were probably the culprits.
Shit maybe even scoop off that top layer of soil and replace with fresh soil. Good as new and the microherd will not allow it to happen again.
The white "mold" might just be a thriving mycorrhizal colony, which is surely a good thing!

WOO Organics!

I would do nothing over 20. Ive also heard they can eat up to 22 hours before shutting off. but 24/0 is a waste of heat and electricity..

most do 18-16 to keep in mind

yeah, not sure from the picture, but if its on top its either iron / sulfur / or zinc
