leaves turning brown, spreading to bud, please help

[jaketheking]

I have an outdoor grow of several plants.
3 of them are the same strain and have a serious problem.
some of the leaves are turning brown , and it is spreading to the buds.
i have no idea what is causing it, i would appreciate any help.

looks like an over feed , nute burn most likely ?

thank you paddysmoke
Could be though I use a very light fertilizer once every few weeks. 90% of the time its just h2o going in.
What is the solution if that is the problem ?

 

[jaketheking]

BTW does anyone know what strain this is ?

I'm not sure, but let's figure this out together. What could be wrong?

- Too little water
- PH
- Under nute
- Over nute
- Bugs

Nutrition obviously is a large domain.

Let's start with temperatures and water. What are your average daily temps?
When did you see the first signs of this?

In general, your plants look dry.

As an aside, your plants look pretty yellow as well. With your feeding schedule you may need to supply more nitrogen through the flowering process than your current regiment provides.

my theory is either PH or lack of nute
water is not a problem, they get a good supply, i live in a hot place they get good amounts of sun. the other plants are doing very well.
one plant has had this problem for about 3 weeks, the 2 others have shown signs in the past few days, getting worse.
I am getting worried.

Look fried, what temps at canopy? They appear to be seeded as well.

 

[shuffledemon]

Good catch Marz. Yeah - you have males in the mix?

thank you again for helping...
It is an outdoor grow, i live in a hot climate, so it can get into the 30's (celsius) .
other plants seem to be ok, and only some of the leaves are browning.
As for seeds, I had a male and got him to "mate " with a couple of the plants , so I have seeds for next season.

Does that have anything to do with it?

I just had a serious heat problem in my own grow that I had to deal with. Yours look slightly similar to what I experienced but it might also be a nutrient problem.

I doubt it. Not sure though - I don't have the experience with that specifically to say, sorry.

Any change in the situation?
