Joe's Fresh Guide to Sick Plant Diagnosis

[Dawn Patrol]

Hi All,

Just after reading through this thread, some plants of mine have taken a turn.
They are in soil, in week 6 of flower and being fed Green Planet Bloei A and B every other feed (whereby, you alternate between flush and feed ), as per the feed schedule.

The yellowing is mostly to older leaves, but not necessarily lower on the plant.
After reading through this very informative thread I believe it to be either Nitrogen or Mag deficiency.

What's the consensus?

If you're six weeks into flower, most strains will begin losing large older fan leaves all over the plant - nothing to worry about.

looks like ph trouble from the leaves, but a pic of the whole plant and close up of the stems would be cool

THE CLAW! I NEED SOME HELP! PLEASE

THE CLAW! I NEED SOME HELP! PLEASE

hey Joe, i am a newbie to the game. I adopted these plants the other day from a trusted friend but they were kind of neglected.When i got them the had fan leaves that looked like the so called CLAW or eagles claw. So im hoping to rescue a them. First off there in all coco core medium and for nutes im using general hydroponics the 3 part formula;the formula is a self setting ph, so i don't gotta to worry about that.

As of 2 days ago they have been sitting in 2< 35 gallon totes grow box, under 6 42 watters, for exhaust im using a inline fan 90 cfm .

any advise on how to get these ladies back on track IC? here are some pics from yesterday morning.

Is this VPD? The weather sucks my balls! Its been below 70 degree and above 70% RH!!!
Every single day these plants look like shit and wont respond to a thing I do or change. I cant set up my dehumidifier in my current situation.
Im about ready to throw these plants away!

 

[joe fresh]

in the last pic i see a bit of claw...the raised serated edges as well...seems to me the start of a build up

 

[TribalSeeds]

They had just been lightly fed with 500ppm and put into fresh coco that was washed really well. They normally get 700ppm, but they still seem pretty light colored.
I got out the dehumidifier but that wasnt good enough, so I had to cut the intake vent. That got it to 75 with 50%rh and the dehuey isnt running.
Still not perfect, but there has been some improvement.

this is my first time posting here or on any MJ forum.

I received a few clones from a friend awhile back and I was informed they are a sativa of some type.

I vegged them and fed them Supernatural nutes from veg til flower and they turned out great (pics of them in album)

I had set two aside for mothers and for my next crop I cloned a bunch and they all took and are now in their 4th week of flower. (this crop has been fed with Tri Flex 3 part base, grow and flower) BUT I noticed that some of my leaves during veg had started to get some mottling/spotting and it seems to be spreading to some plants moreso then others.

I have some pics that are from my DS-V2, (downstairs, veg, 2nd crop)as well as some from the US-F1, (upstairs, flowering, 1st crop)

I have perused the interwebs repeatedly trying to find out what my problem is, these are my first grows in a few years and I am not new to cultivating nor am I all that and a bag of chips, just a old school kinda guy who enjoys self medicating and growing good weed.

Thanks in advance for any help.

I am an amateur at best, but if I was looking at the right pictures, you look to be running monster clones that should have greened up by now based on their size. I mention because purple petioles is generally indicative of a def or lock-out. I would simply make sure your dialing in your P'sPM/EC and PH and let it go for a week to see if the new growth lacks the spotting. Or not.

What do you think guys?
Sulfur deficiency?

Excellent Guide and pic's

thanks for the info, helps alot with pictures.

What do you think guys?
Sulfur deficiency?

Not likely Sulfur.

What are:

EC, Ph, Nutes you're using, res temp, method of irrigation, and a little about set up.

 

[Green Devil]

Not likely Sulfur.

What are:

EC, Ph, Nutes you're using, res temp, method of irrigation, and a little about set up.

About 550ppm (will stay in veg until 14th of May).
pH is about 5.8
Going with GHE nutrients (Lucas Formula)
Water temp is about 75.2 degrees Fahrenheit.

Set up can be found here!

The curled leave edges are Mg deficiency? Are you certain? I have a GSC plant that is showing this and I thought it was high VPD that caused it (low relative humidity). I Foliar sprayed and moved lights away and raised humidity for 10 to 40%....problem went away. These were clones transplanted 4 days previously into FFOF 3 gallon...so no nutes were given. I did raise Ph subsequent to the other actions....maybe the MG was the real problem and the ph change fixed it.

Great help!!!! Thanks

Great help!!!! Thanks

This is my first post here, so hi all. I am in need of correct help, as I have stumbled through this grow of mine and now find myself 2 or 3 weeks away from harvest and I feel like I have some issues I'm not addressing or that I don't know about all together. Since I don't hav time to mess up and fix whatever I do before I harvest, I though asking help would b a good idea.

I found this site and your thread. I was extremely impressed and hope I can find more direction than you have already given me.

My two questions are:
What is wrong with the plant in the first pic? I have cut off leaves that looked like this but at any given time the plants has 3 or 4 leaves that look like this.

Second question is should I remove the popcorn buds on my flowering plant at the bottoms of the branches to help improve the main bud at the top? Or am I too late with only a couple weeks till harvest?

These plants are under a 1000 HPS and I was on Age Old nuts till April 7 I changed to general hydroponics. They have been flowering since March 17.
