Brownish splotches on a few fan leaves

[Kalyx]

Noticed these markings with in this past week, it appears to only be on a couple of the fan leaves of my Fuzz #4 and looks like a leaf on the Pineapple express has this also. I believe the pineapple express may have just had a leaf that was burned not sure if its the same.

All the plants are very healthy, just a couple of the fan leaves have these brownish splotches on them. None of the tips on any of the plants are showing any indication of nutrient burn. Plants are in an organic soil mix have had no added feedings. All plants last week did receive a top layer of earthworm casting and diatomaceous earth. Receiving one watering since that time. Was planning on adding a feeding of some bloom nutes to plants with the next watering.

My initially thinking is that this is possibly a PH issue or even a phosphorous deficiency or combination of both. Not really worried at the moment but would like to diagnose and nip it in the bud before this becomes an issue. Plants are at about day 28 of flower right now, looking great, smelling great. This could be nothing but first signs of stress or trouble I want to get to the bottom of it and fix the issue.

First 2 pictures do have a little droop as the Fuzz was watered a little late.

This leaf is the worse in terms of the damage.

Have never seen anything quite like this with my grows so really not sure what this is. My assumption the main culprits are PH or Phosphorous issues. This is a picture of the effect plant 5 days prior to these new pictures. Can see that the plant is health and seems to be doing well. You can notice though that it was initially starting on the major fan leave on the main stock on the left side of the picture. It is hard to notice but can see where it first began.

You can also notice on the lower right hand corner of the following picture, the other leaf pictured where signs first started.

If anyone has any ideas of suggestions please chime in with any thoughts on the issue. Any help or solutions of similar experience would be greatly appreciated.

bump.

I'm experiencing the same thing happening to some of my phantom cookies. other than the splotches they are extremely healthy

ph lockout causing various deficiencies, would be my opinion also. A good flush at ph 5.9 and ec of 1 may help.

yea i should've known.. haven't been using my meter for a while and the babies were doing just fine.. thanks Green

Spray anything recently?

 

[Kalyx]

thanks everyone for the responses so far.

@RSG So you have the same thing going on? Are you growing in Soil? My plants are very healthy looking just a couple leaves like that, glad to hear yours are healthy as well otherwise how far into flower are your phantom cookies?

@Green81 My initially thought was PH, I will need to check the soil to see what it is will test the run off this weekend I guess. I have never had PH issues with soil before not something I usually worry about. I guess I should see if it is the problem before adding any nutes incase the PH is causing a lockout which was a thought.

@Mikell Nope haven't sprayed anything, in terms of something getting on the leaves its possible some of the diatomaceous earth or worm castings. These leaves are higher on the plant, have had the DE get on lower leaves and has caused no damage in the past. The only other thing that could have come in contact with the leaves would be some yellow sticky traps, usually will just tear part of the leaf off it that happens though. I could always be one of those variables but the looks of it though Im thinking not.


If not PH im thinking its a Phosphorus issue, was wanting to add a feeding of some AOO bloom nutes with the next watering. Thinking I should maybe see if PH is the issue first.

I find it very odd that this is by far the smallest plant in the garden a serious runt compared to the others. Would think the bigger ones would be showing, maybe the runt is a nute hog?

ye kalyx I'm growing in soil. i literally flipped them like 2 or 3 days ago so i could sex

Gotcha, well I will make sure to keep updated with what I find out, thinking shouldn't be anything to serious or difficult to fix. Don't want it bringing things down at this point. Such a vital stage in development and so close to the finish line.

 

[RSG]

yea you need the plant to uptake all the nutes ur giving it. and if ph is off then plant wont take in the nutes as well as they should b. let us know what the issue was. good luck

PH issues wouldn't cause brown spotting like that on one or two leaves. The plant you showed above looks mostly healthy and happy.

It looks almost like thrips damage to me.

Got any sticky traps set up? What kind of pest control program do you have going?

HB.

yep do have yellow sticky traps up and also actually have a blue sticky for thrips. Have replaced all of them last week. The blue sticky has caught absolutely nothing, neither had the one I replaced. The new yellow ones have been up for about a week and haven't seen any gnats on them only a couple house flies the past week.

Few weeks ago did have some gnats that got in the house have been checking top couple inches of soil every couple of days for past month of so, has been clean haven't seen any creepy crawlies, other than one earwig that was in one of the pots.

Gnats really haven't been bad only a few between sticky traps and using diatomaceous earth they have all but disappeared.

Haven't needed to used anything other than sticky traps and DE at this point

It's not over watering is it?

I guess that could be the case if the soil isn't draining properly. It seems to have good drainage always check the top inch or 2 of soil and make sure its dry before watering. This girl has been watered avg of about 2 times a week.

I will actually check though deeper into the soil, possibly deeper in its retaining the water more i guess that could cause it.

Wouldn't I be seeing a lot of other signs like droppy leaves and such before seeing damage like that to the leaves?

Did it get better/worse? Have you tried anything. I too have found similar splotches . I have a rich soil mix and doubt a deficiency. Keep posting!

Ya the problem has been solved meant to post up earlier in the week but was unable to. Was a high PH issue with the water I was using. I'm assuming it caused a nute lock out in the fuzz plant. My young vegging plants were hit the hardest, looked like over watering with them.

I have fixed the PH with the water, actually finishing up these girls on bottled distilled water. Have also been adding fox farm kangaroots root drench and microbe brew to waterings. This has really help all the plants quickly rebound and recover.

Vegging plants are no longer having their growth stunted, they have really perked up and exploded in new growth this week. The fuzz plant with the blotching/spotting on the leaves has no new damage nor do any of the other plants. The fuzz has been really fattening up, and looking great.

Clearly getting the PH on the water adjusted was huge but the root drench and micro nutes were key in restoring health in the roots and fixing any lockouts. I hope this Helps if you are having a similar problem.

I want to thank everyone that offered help and apologize to all for taking a long time to get out an update have been really sick the past week.
