Hi everyone.

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.
 
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....
 
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...

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

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?
 
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
 
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?
 
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
