WTF is this?

What is wrong with my leafs? I have looked everywhere for the answer or a cure and have come up with nothing I cant fix it cuz I dont know what it is?!?!? It looks like bruising if I were to describe it, with browning sections of the leaf towards the leaf tip. Anyone have any ideas? Im gonna take a picture Ill be back asap

Here is a pic maybe this will help. . .

you need to provide your grow conditions if you expect anyone to help you (generally). How old? What type of nutrients are you using? Are u growing in soil, rockwool, etc? What strain? What breeder? How often do you water? etc etc

The Info:
Hydro set-up flood and drain 2x daily 5 min ea.
3 Plants started from clones 3-4 weeks old (10"-14" tall)
using rockwool cubes
20/4 light cycles with (1) 250w MH and (1) 250w HPS Sun Systems VII combo balast with 2 bulbs and reflector
light its about 12-14" away pH is about 5.8
Using FloraNova at 1/2 strength with Floralicious supplements
Thanks again to anyone who can help out. . . .

Are the 2x250w bulbs (equaling 500w correct?) in an air-cooled hood? Does the hood have tempered glass? 10-14inches away on clones with 500w is probably way too strong for them. They need high humidity but u don't want to burn them.

well I should change the age I copied and pasted from my other threads they are over a month old now, and quite a bit taller about 18" Im flooding 4-5x daily now as well but no i have no glass on the hood. . .You are correct, the bulbs total 500w yet, the they put off a relatively low heat for the light output of 51,000 lumens combined between the two at 12" the tops of the plant are almost cool to the touch. . .

did you spray with anything?

I sprayed neem oil and where it didnt come off all they way it looks the same as your pic.

I've had plants that did the same thing. Never turned out to be anything serious. Betcha that one of the biggest fans on your plant and probably one of the first. I wouldn't sweat it to badly if the rest of the plant is good. Those 1st big fans always seem to look funky when compared to the rest of the plant.

Thanks for the response earlymornin here is picc of how they are doing now. . .

Neem oil huh, well thanks for the input fortunately I didnt use any sprays but still no answer as to my browing/bruising, weird, well i guess ill just have to hope it doesnt happen too many more times only 4 leaves were lookin bad the rest are nice and green I just posted a pic of them now let me know what you think. . .

they overall look healthy to me


If the problem spreads i would be worried, but for now i think ur plant looks top shelf!

yeah look real nice. that color on the fans may be strain specific. if you're feeding at a high level you may wanna back off a bit but other than that looks like its gonna be some kill. Good luck.

everything looks nice!!! just see if it spreads, if it does and the leaf its on has more then 50% brown then cut it off. you should have some nice herb though! and from the other thread you have about the ph it could be that because its not good to add ph down everyday. I also used the G.H. ph down and it took alot to get it down. try the A.N. ph downI just got it and love it but be careful with it one cap took mine down from 6.7 to 5.6 and I had 30g in my res. hope I helped and good luck!

Thanks for all the responses guys and all the complimnets will be relayed to my ladies I hope it will make them grow even bigger. . . keep them coming and A.N. pH down? cant find that local is it online?
