Brown Spots on my Silver Haze Clones

[EarlyDayz]

Hey Guys my current grow consists of Silver Haze Clones and 2 Strawberry lemonade both are doing well but the Silver haze has brown spots on their leaves, nothing on the SLemonade.
More worried at this stage as they are in flower and know they need the leaves ATM. Any suggestions?

Looks like damage from water on the leaves. Is that where you water them? Stop getting it on the leaves especially during lights on.

[EarlyDayz]

Water is always applied to the roots. Never through the foliage.
I had the same issue with my last grow and the buds suffered.
The Strawberry Lemonade sit right next to them and nothing on those leaves.
I thought it might be common with silver haze.

You have given us no details, we dont know what the PH is, the media is, etc..
From here it looks to be a PH/root zone issue, there is a link at the top of this page "Plant Problems" follow it and read.

Some more pics
First 3 are the spotting issue. These plants are clones from my last grow. That silver haze suffered the same leaf problem.
Last 2 are the strawberry lemonade which has none of the issues.

My Tents are in the shed in the backyard and here in Australia we're having 35-38C or 95 - 104F.
So while I'm airconditioning the shed the heat still fluctuates around 28-30C at the hottest. The tips of the plants are I think a reflection of that.

Any Ideas?

I wont be much help with a hydro typ grow, I grow in soil. But did you prep the coco? I have read it must be prepared before use.

IF we were not in covid days, I would luv to come down under and visit your country! I do better in hot than cold, LOL but for now I'll have to stay home.

Of my city of my city...........

[EarlyDayz]

Growell are you saying the plants are showing a potassium, deficiency?

[growell]

Looks a bit like that but mr furley knows better than me if he saying toxicity i would go with him mate maybe its the plant if it did it last time and you are doing nothing diffrent from the others plants may be its really tempermental to pottasium or something else try changing your feed see if it gets better or worse i wouldnt grow that strain again mate

[EarlyDayz]

Growell I agree won't be growing Silver haze again too temperamental for me.
I would imagine different strains are easier and some harder to grow.
If I hadn't taken clones I would be growing something else.
