Looks like a sign of some fungus..... you say you are into flower? What is the Residual Humidity?

 

[bigweedo]

See..that might be my problem. I make sure it doesn't get over 80 Degrees in the grow room, but I don't have anything measuring the humidity. I also only have a 50 cfm fan as an exhaust, but since the temps were around 75-78 i didn't think the humidity would be a huge problem. What would be the cheapest way to measure it?:afroweed:

Also another one of my plants has leaves that are curling inwards pretty bad... is this from humidity issure too? Here is a pic

Any hardware store will sell a hygrometer... wal-mart..... cheap $20 at most.... it will record the temp/humidity and stamp the high/low so you will know what the extremes are for both temp and humidity... good cheap investment ... eace:

You sure walmart has them??? Ill go there right now if that's the case!

I'll check but yeah pretty sure..... hhmmm couldn't find em on wal-mart but if ya have an Ace... well here's a link http://www.acehardware.com/search/index.jsp?kwCatId=&kw=hygrometer&origkw=hygrometer&sr=1 eace:

PS... I prefer the digital one... sorry I misquoted the price earlier.... but it's worth it... that way you know what the temp and such get down to when lights are off... and when the temp peaks in the summer....

how much nutes are u useing? kinda looks like a nute problem.

 

[bigweedo]

So i went and bought a hygrometer, and it says the humdity is 56%. I don't really know if that is bad or good...the temp is 78.
My Nute breakdown:

I am using b'cuzz nutrients. Every three days i water with full strength nutes.

2Ml-0-2-4
2ml-3-0-3
I use those for soil nutrition.

3/4 tsp Growth stimulator (1.0-0-0.7)

1.5 ml bloom (0-0-0.7)

and 1.5Ml pk 0-13-14 (called pk 13-14)

SHould i cut back on the strength?? I don't know what to do:afroweed:

try and get that humidity down to 40% when flowering....

 

[bigweedo]

Do i need more ventilation for that?

 

[Magoo]

yeah.... get temps down that will help, hot air will hold more water vapor than cold air.... if you can get temps down... you'll see the humidity drop... a simple fan will achieve this for you....

 

[bigweedo]

I turned my oscilating (sp) fan up one more click to the top knotch..hopefully this works. Know of a cheap fix???

when flowering just try to keep the humidity down 40% ........veg likes it up there a bit more.... but when those buds start plumping up, and the plants start squeezing each other... space becomes limited and high humidity sets around stagnant rooms.... fungi, mold, and other fun stuff to deal with (not really) find a nice place to hang out......
