hashberry problem

[icee]

Hello
I posted this picture in Mandala's forum but they sent me here.Anyway this is a clone of the plant which had the same problem.It starts around the fourth week of flowering from the top of the plant and it goes downwards.Rest of the plants in my garden look happy under the same conditions.I looked at lots of pictures but didn't find anything like this.

It's not heat stroke.Plant is in 20L pot and is fed with algoflash(1/4 of recommended doze).I regulate pH of the water with vinegar.

I would recommend that you upload that picture here on ICmag so members don't have to go to unsafe off-site links like photobucket.

More importantly though, if you want your problem to be properly diagnosed you should answer Stitch's survey. If you're growing in soil fill in the top set of questions, if you're growing hydro fill in the bottom ones.

Somebody sugested nitro tox.I'm not sure doesn't really fit the description.Plant grown from seed i took this clone from had huge root system and yield was above averige.
I really hope someone can figure this out.

 

[MynameStitch]

Can you please take some more pictures of the problem, but please make sure the HPS is not on as it hides the problems well.

 

[icee]

I moved it away from HPS.I'm not really good with camera.Few more pictures are in the gallery.Cheap camera,can't zoom.

If your talkin its yellowing some hashberry just go yellow and get leaf drop in mid flower I can show you some pix from mine, I call it the yellow pheno. No matter how much you feed it they stay yellow

 

[MynameStitch]

It is normal for any strain to really go yellow towards the mid to end of flowering, you want it to to ensure your plants are using stored nutrients to help with the final flush phase.

 

[icee]

I obviously suck at taking pictures.I'm not worried about bottom leaves yellowing.I'm worried about top leaves curling inwards and down.Took two more photos of the leaf i cut.Previous experience sais that by the end of flowering this problem is going to spread all the way down and she's going to have branches with buds and few sad leaves hanging on her.

 

[MynameStitch]

Looks like it is being overwatered, the water in the bottom of the pot is staying too wet for the roots at the bottoms causing the top to look curled under, that is a sign of moisture stress, you should wait a little longer before watering again.

Thanks Stich.I'll try that
