What Is this on my leaves? Please help

[thc is good for me]

So some of the leaves on the plants im budding have these spots on them and I dont know what there from if anyone can help me that would be great.

Is it maybe a Nutrient problem ?

Hello Thc

Soil or Hydro?

is it indoor? could be calcium def., manganese def, or phosphorous def, since your in the budding stage I would guess the latter, but it's hard to tell when they are not here in front of me, knowing how your growing, what your feeding etc. If it's outdoors it could be any of the above ,and also possably leaf septoria, this usually doesn't occur indoors though I understand. good luck and a few more details of your grow may help people help you narrow down the possabilities

 

[legalize_freedom]

duh...I just realized this wa in the general "INDOOR" gadening so you can disregard the comment about leaf septoria, and it is pretty rare anyway even outdoor, but it does put spots like those on the leafs. Anyway give us some more info on your grow so we can get ya figured out. Also are the spots on old growth or newer growth? top of the plant? there are alot of knowledgable people here to help you, and they seem to be very happy to help. Again good luck!

I say it P def. I have two girls at 6 weeks in flower that just showed up this week looking just like the picture there. I have upped the P in the Res (DWC) so I will know in the next few days how well it works.

 

[thc is good for me]

I am growing in soil indoor I have been using open seseme for nutrients.

So what is the best way to add P without adding a bunch of other nutes that are in open seseme

You have to find the cause of the problem to solve a problem.

Here Are some pictures Of my plants I am having problems with.

Here is also a Picture of the roots of one of my plants I noticed when I was re potting They look like they are part of the roots but could they be from spider mites I had a problem with spider mites before but I bought these no pest strips that kill mites and there are no signs of them on the leaves. Any ideas ????

 

[Kcar]

Um, they look over-watered and Open Seasme is 5-45-19 an additive,
are you using any base nute?
Also looks like a ph prob with your water.

No I was only using open sesame. I have Ph up and down but I dont have any Ph tester strips.

The first thing you need to do is to check your pH. You could have nute lockout and dumping more nutes in will not help.

so I have to buy those ph test strips or is there a way to do it without buying anything

 

[Dr. Manny Bowles]

I have had the same problem and from lots of reading was under the impression it was a Magnesium deficiency. For me it always shows up about 2-3 weeks into flowering. I have Skunkberry in Ocean Forest soil, FF nutes/Liquid Karma, and have used epsom salts on occasion with feedings but still had problems. I use the FF nutes at about 1/2-3/4 strength during flowering and I do use tapwater, which around here is about 160ppm after sitting for a day. I feed/water at 6.3.
This grow I'm adding about 4 TBS of epsom salt to 5 gallons of soil, hoping things will turn around:farm:

 

[IRISH]

you really need a good ph test meter. those strips can throw you off by a whole point, sometimes even 2-3...

 

[3rdbase]

im a hydro guy but it... looks like nute burn for sure it must be really high ..week 6 though ur plant could be just slowing down...i dont think its a lockup or the whole plant would be suffering ....def a burn dude when u grow ph is everything will kill ur plant if its off by locking up nutes or throwing nutes off in disproportion ...need to flush then chill for a couple days then add nutes in the proper proportion..gl

 

[legalize_freedom]

dang! fill out hippies qustionare (that is impresive!) if you can't narrow it down with that you never will!!! Nice Hippie! I use open sesame from FF also, but like another member said that is an additive and should be used in conjunction with base nutes. Open sesame is for the beginning of flowering to be used with (what i use) ff big bloom, and tiger bloom. But what everyone else is saying is true first and foremost you have to be sure that your ph is right. If it is off then you are not makeing the nutrients avaliable to your plants. You can feed it all day long and not get anyresults because your roots aren't able to revieve the nutes. With that being said, get an ACCURATE ph reading. Make corrections as necwssary, and then start feeding a FULL nuterient line. Open Sesame is only one component of a 3 part soluble addative pkg. but needs to be used with at least a good all around npk fert for flowering. Good Luck!

I believe it is a fungus since the brown spots are crossing a vein. So.....Lower the humidity, increase circulation. I don't think there is a nute problem that quite looks like your deal.
