I would guess that the two most accused culprits tor brown spots is Calcium deficiency and/or PH being out of the desired range. When I go to the GWE page on problems it comes up with half a dozen possibilities. Many of them incorporate additional symptoms that you do not have, such as yellowing, etc. I suggest you click on "Diagnose Sick Plants" at the top of this page to check it out.
Good luck and let us know what does fix this.

One leaf. That's nothing. Did you touch your plant with moist hands maybe?

[South Sierra Dude]

And may I add, your plant looks awesome; good job.

First, Thanks all for replying.
Yeah. I watered her from the top last 3 watering but i didn't touch any leaf. This symptom is spreading fast. i see it on many leaves at top

Nothing against tap water but you do need to know the PH of that water. And I have never heard of anyone getting problems from adding some cal/mag.

feeding schedule and amount please...
what is your ph going in
what is your ph coming out
what is your medium
what are the products you are using
what is rh
what is temp
how old is plant and in what stage
without all this info no one can have any idea....

[Flockshot]

Hey Green, do you think we should have a 'permanent post' like the Welcome post, that gives growers a list of information that they should try to give (if they know) when asking for help with plant problems?

[alltatup]

I agree with Flockshot: Green75 has to ask these same questions each time someone comes in with a new problem!!

[Chemichael]

exactly what green said- and GWEs diagnosis page is damn good-

to me, that looks like water damage as I have seen that enough before. With the touch of some light burn perhaps - too close to lights? Im seeing only on what looks like the highest growth...

PH: 5.8-6.3 in and 5.7-6.2 out
Medium: Coco/Perlite 5:2
RH: 45-55
Temp: around 26 when lights are one and around 24 when lights are off
Day 63 of veg, 7gal pot, GH flora trio Nebula's Chart

Recently, lowered the Ph that is going a bit, around 5.8, and watered her from the top

never give anything under a 6 ph....
if your pots are dry then I would like you to water only right now at 6.5 ph.....do this twice...
6.5....no higher no lower till you report back after two waters with 6.5......then hopefully we go back to 6 with a feed

[Green75]

I was going to look you up today and ask...again..happy times

[Iammygod]

She's super green and healthy now. Thank you again man. I'm ready to initiate flowring

Should i lower Ph going in slightly for flowering? Is it necessary or i should continue giving her +6.3 Ph?

[Green75]

Yes..just stay between 6 and 6.5....I myself always aim for 6

Awesome she is doing good..would love to see a pic...

You and her did the work..good job...patience is key...huh

i owe you and Nebula's great articles . Thank you, both of you 2

[Green75]

Damn dude...she is stunning...real beaut!!!
congrats...she will throw nice nugs!!!....and a lot of them

Good show

[Iammygod]

Congrats to you. You saved her. She's yours(i will smoke her buds for you )I just raised Ph (and nutrients dose 30% because my runoff PPM was lower than what i was feeding them).

Now i can recognize how much nutrients my plants need. If the runoff ppm is much lower or higher than what you have feed them, that mean your plants need more nutrients and are absorbing Ions they need fast and releasing Hydrogen Ion or Hydroxide into the medium.

Before you advise me, i was measuring runoff Ph and PPM without knowing what should i do with these numbers )

Very nice save Doc Green , All problems are recent and they let you know it's happening be it over watering ph or light burn , so if everything is going good and bam something is wrong you changed something. They look great now
