Hi guys not sure if this is a big prob or not but my plant is about 2 weeks into flowering and some of the leaves are starting to curl under but its literaly just the tip on the centeral leaf of the big shade leaves but everything else looks ok? i do have a slight prob with humidity i can only seem to get it up to 15/20% which i know is low!
i have heard from a m8 that leaf tip curling can be a sign of something good but he couldnt remember what?
i have included a few piks for ur help with the issue
also i feed once a week and alternate from just water to low N high P flower nutes.
the plant is himalaya blue diesel.

20% humidity, is fine for flowering, close to ideal, actually. I try to keep mine around 25-30%, so 20% isn't bad at all. Also, you'd have about zero chance of bud mold, which is another plus. Drop those temps, and your plants will be alot happier. That high heat will hurt your plants, alot more than the humidity being a tad low. :)

I was talking about flowering, specifically. Veg is best at around 45%, flowering, is more like 30%. There seems to be two opinions on that subject, around here, with one half choosing to keep humidity up around 50%, for the entire grow, and the other half preferring lower humidity during flowering. I prefer reducing the chances of bud mold, over having higher humidity, as many do. :wink:

humidity on its own should not be a problem as long as you keep an eye on the "night" temperatures, cold nights = molds etc,

On my plant I trimmed the tips of the leaves off as each layer begins to come in because a friend of mine that's been growing for 20 years said that it's all about your neuts shooting to the top. Trimming the tips i think...would help with that extra growth that isn't needed, and on your pics at the top it's very easy to see that extra growth i'm talking about.

millerboy: if u have fed them N and MOASH has diagnose(spelling) both of our grows of N toxity then lay off that and flush,reg. water for a bit.THANK MOASH

thers a few ways to regulate PH u can get PH down and up i think.thers some stuff u can also put in but i forgot,sorry. SHOOT for 6.5 ph
LEmonGblazin:ive heard good things and tips about trimmin off ends of leaves...HOW IS IT GOIN FOR YOU?! i thought i may do that too here pretty soon,since i can def tell the top of the plant isnt gettin fed as well as the bottom branches.
