Nitrogen Toxicity I think. Help!

Mainline shouldnt require less nutes. I use FF soil and nute/soluable line and follow the schedule to the T. I have no problems. You have NO signs of N toxicity. Your leaves arnt clawing they are drooping from heat stress. Not all strains act alike, some hate wind or high temps, some can handle it. One mozaic leaf doesnt signify broad mites....
I used a infrared temp reader on the top of the plant and it read low 80's so I didn't suspect its the temp. Today was the 1st time hearing about broad mites. I'll check just in case though

I would just water her only for a bit and she will be fine. Last pic looks like broad mite damage. You will need a microscope to see them. Google "broad mite damage on cannabis" to see what I am talking about.
He is right you know.
Yes, high N so simply water it away,,,,no nutes for a week.

Don't bother looking for the Broad mites. They are the size of the diameter of a whitefly leg! AND,,,,,yes pic 3 is Broad mites!
Use Forbid 4 F.......your going to waste your time with neem. They actually burrow into the leave veins and neem or other "contact" killing sprays won't work. You must get the chem into the plant.
Forbid IS safe.
Find small low price amounts on ebay.

get ur 1000 wat closer man ur 6 weeks looks like my 2 weeks under a 600 hps
WHAT? CLOSER? No don't! NO closer then 18" for a 1K.

and not to be rude man dont use fox farm poo poo poo go canna or h/g or dm next time
My vote would be for Dyna - Gro or Hesi FF does make some good things, so it's not "poo poo"!

T I might try spraying it with green cure. It actually killed some root aphids I had before.
I guar - en - fucking - tee , you did NOT get "rid off" Root Aphids with Green Cure!!!!!!!!!!!!!!!!!!!!!!!!!!!!! And THAT maybe why your not getting the proper growth!!!! You still have them, your just not seeing them yet......

One mozaic leaf doesnt signify broad mites....
With the curl it does! Kill them now.

Damage
Broad mite attacks the growing point and the underside of young leaves causing hardening and distortion. Broad mite damage is often confused with injury caused by hormone herbicides because in both cases the leaves become claw-like with prominent veins. Grey or bronze scar tissue between the veins on the underside of the leaves distinguishes mite from hormone damage. Broad mite infestation can sometimes be confirmed with a X 10 hand lens although they have often disappeared before the damage is noticed. The characteristic egg can be seen near the veins beneath the leaf as a translucent, flat oval with a stippling of white dots. The mite itself is flat but is less easily identified than its egg.

Broad Mite
Polyphagotarsonemus latus (Banks)
Tarsonemidae, ACARINA
Description and life cycle
The egg stage is the most easily identified microscopically, they are clear,
oval shaped with the surface covered in white pimples or tubercles making
a spotted pattern. They are usually found in the growing tips on the
underside of newly formed leaves and under the calyx of flowers and fruit
or in protected depressions. The life cycle through egg, two nymphal
stages to adult takes between 4 to 10 days depending on temperature, with
up to 20-30 generations a year if conditions are favourable. Adults are
oval, tapering slightly toward the rear end. Females are very small approx 0.3mm long, barely visible
without magnification, males are slightly smaller, they are both transparent to yellowish green in colour,
stationary when feeding, moving slowly when disturbed, the nymphal stages resemble the adults. Adult
broad mite only live from 5 to 13 days the female broad mites laying 30 to 76 eggs over this period.
Crops attacked and problems caused
Broad mite is a major pest in the warmer parts of Australia and favours capsicum plants. It is a minor pest in
temperate Australia but will cause severe damage when conditions are favourable. Broad mite usually
attacks the young growth of a wide variety of vegetable crop plants especially capsicums or peppers and
many ornamentals by injecting a toxin from their saliva as they feed so that a few mites can cause a lot of
damage. It has been known for many years as a pest in glasshouses and of summer grown vegetables and
ornamentals. Mite damage is often reported when conditions are warm and humid. High humidity (80 to
90%) and temperatures above 25oC are favourable.
Feeding by the mite may cause leaves to bronze and thicken, become brittle, corky or cupped downward and
narrower than normal. Young stem growth may be distorted and stunted with young terminal buds so
distorted that flowers do not open; heavy feeding can cause young terminal buds to die and drop off.
Severely damaged plants could die. The symptoms of broad mite feeding are often confused with viral
symptoms or hormonal herbicide damage.

I wouldn't jump right in and say broad mites. Personally I think you will be good. just use plain water the next few. If you are concerned about it after harvest just get rid of the soil and trim and be clean about it.

Nice piece on the Mites there Doc.

Most of the time I simply remove the infected leaf and burn it. They don't seem to spread very easily.
I haven't had a problem in a very long time.....but I always keep the Forbid around for just in case.

A lot of people will say that's mosaic virus - Sunn Hemp strain. The name is a misnomer due to the fact that Sunn Hemp is a BEAN and not cannabis.
I have yet to see a REAL mosaic infection in Cannabis!

Thanks Doc for chiming in! And everybody else too!

I will try this whole week with water only and then continue to feed next week. So its been water water (today) and probably water again then feed by late next week.

I will look into Forbid. Especially if its safe and possible to treat other bugs too? I'll also remove the 3 leaves that has these curls. I looked under the infected leaves yesterday with a loupe. I saw small little clear egg looking things but they werent moving.

I would love to switch over to dyna or hesi but I have so much ff nutes still.. Idk what to do about that. I mean can I use dyna and still add some of the ff nutes I have so I won't waste it? I have all 3 base and 3 solubles plus kangaroots and microbrew.

1st grow i ran into root aphids. I didn't use greencure to fix the problem but I did notice they died when I sprayed the ones I saw. Ever since I haven't ran into them again.
