Ok so I'm concered about the very light looking new foliage thats comming out of the top of the plants, 2 plants out of 6 are showing these signs. Also one plant has thin leaves that are very dry.

Thank you in advance!

Try 18/6 lighting. New foliage is usually a lighter color.
I haven't had leafs get thin on me but I would suspect you have low RH.

RH? You mean PH right?

Cuz i googled RH and didn't get anywhere...

RH=Relative Humidity. Low RH can cause problems. I would suggest getting that bark out of there too. Other than that they look pretty good, maybe a bit overwatered. :weed:

Ah yeah my RH is about 30's when im not home and i keep it up at 40-50% when i am home.


Its ceader woodchips, i read some place that its a natural pest protection. Is that not so?

That is true that cedar is a natural pest repellant. Some woods are acidic and may play havoc with your pH. You should probably be fine with them on there but take care not to overwater. The wood chips act like mulch and keep moisture in the medium which can be a bad thing with cannabis if the medium holds too much moisture for too long. Overall, they look pretty heatlhy. Good job!:weed:

Yeah i was hoping for it. There's a pritty raw ventilation right now,the white fan that is visible. need moisture to be evaporated constantly to keep temps and RH in check. Its not stable and that's hurting my plants. :(

I also had humidity problems. My grow closet is cedar-lined, so it absorbs the humidity. I run a cool mist humidifier during the light period. Turn it off at the same time as my lights. This keeps the RH between 40 to 50%. Don't keep it on 24/7 or the humidity will get too high.

Lookin good, Hey 70% RH is high. You want around 50%
As the plants get larger they will produce humidity so its gonna get higher. Maybe you should return the humidifier and get a dehumidifier.
