light burn??
    #770169 - 02/25/15 06:29 PM (1 year, 9 months ago)

Is this light burn? I recently got my 400W MH light set up last night and when i woke in the morning some of my leaves have seemed to crispify a bit. Ive been treating for mites and see no sign of them on the underside of leaves in the last week or 2 and I did a follow up treatment spray last night just to make sure.

Seems like standard mite damage to me.
Generally when a plant is attacked on a good sized area it responds badly in various ways.
nutrient uptake & growth will slow

Reduce lighting slightly and feeding altogether until recovery is my recommendation.

The mite resource page on here http- ://www.growery.org/3041/How-to-Kill-Spider-Mites-Get-Rid-of-Spider-Mite-Infestation-on-Cannabis-Marijuana - is that guide pretty effective? i used the Soap & Water Plus Version 1 as described, a few times and haven't been able to see any mites in awhile. If this is an ineffective method is there an effective one? My ballast has a 50-100% power dimming option, by cutting lights a little would that be enough to cut it to 50% or should I cut it off and stick a few cfls back in there? This is my first real grow. Thanks for any input.

How hard it will be depends on what kind of mites you have.
I prefer killing them to removing them since they always seem to come back otherwise.
If your light is too close just raise it up a bit.

Keep your light on 100%, go down to 75% at the lowest. All of those neem oil or rosemary oil and soap and water tricks absolutely don't work. Just buy an effective pesticide and spray it before you go into flower. Spraying water everywhere during flower is a good way to get mold.

The 2nd pic looks a lot like a light burn.

Bright light makes plants work and reduced light can help recovery. Especially in times of diminished nutrient uptake.

The second picture looks like you got some water on the leaf, and THEN the light refracted and burned it. 

You definitely have mites.  The hot shot strips works well in non ventilated ventilated areas, but then you really should wear a respirator if you're going to be in that area.  I would recommend getting a bottle of avid.

You are prolly right about the water burn, because I sprayed em with dish soap version 2 tek and waited prolly an hour for it to evap before putting them back under their lights. my grow is in a closet in a room of its own. I am worried that the hot shot strip might effect the tubs of fungus I have in the room outside the closet. Ill pick up some avid and hotshot after school today.

Bingo, just look up the active ingredient, and order a generic version of it.  It lasts forever dude. 

Remember to spray right before your dark cycle

Hell yeah. what he said^
I got a small bottle of it ( enogh for a few lifetimes) on ebay for 10 bucks w free shipping. I think its called abamectin or something.
  Its practically scentless surprisingly. Definitely geared towards all stage mite death specifically
