mystery plant ailment..https://cannabis.community.forums.ozstoners.com

[chorusverse]

Has anyone dealt with this before? Thin leaves, crepeish leaves, upturned leaf margins, yellow tips.

Virus, Fungas or mould/mildew of the systemic variety is what I am thinking. These plants are jack herer(j) and shiva.

Thanks in advance for your help

imo

they are suffering stress from a toxic buildup of waste nutrients in the pot

the solution is to flush asap

 

and while you run the flush

 

spray with high potassium spray like liquid kelp for shock

never let the spray touch hot lights

spray with the lights off

 

the roots are suffering and unable to support the existing leaf

switch to foliar feeding till the roots recover

 

when the plants not healthy their immune system is down and they become targets for insect attack and fungi to grow

keep a keen eye pon them till they recover

 

what is the grow space air temperature??????????

maintain the temp in the mid 20ts

Thanks radic I know you would be to the rescue

 

I am going to do exactly as you said, because, why not. But a little more info this has been going on for a friend for a couple of years now. and said is not the only one. I received some cuttings from someone else on the other side of the area, different strain but same symptoms. These people have brought them to me because I have a small zero exchange setup (no air in our out, carbon scrubbed, co2 monitored, humidity and temp controlled) that should technically not be subject to flawed environmental conditions. I grow in canna terra, hand watered with piranha and tarantula plus weekly fresh water flushes with microbial (quaternary ammonium).

 

Radic I feel like salt is not it, but what you said about root damage strikes accord. I will still take all the steps you suggested and would love it if you would correspond with me on the subject some more.

Thanks also radic for all the time you give to people om these forums Bless

28.5c

1200-1500 ppm co2

55% RH

And by the way, the only reason i put them in my cupboard was that I thought the same as you...toxic salt buildup resulting in rhizospheric injury.
