Sick girls in Rio De Janeiro

[svenghalli]

So I found my self in Brazil, Rio to be exact. They have a small medical program and Im legal to grow 30 plants in my house. Ive grown in Cali, and Maine and now Rio. But I have something i cant identify and would like some help and opinions.
I'm running rockwool, athena pro 2.8-2.6 ec, my temps average 80f, humidity avg 70% (remember I'm in the climate of Rio) The plant in the pics is the main culprit but i think some of the new growth is being affected too. So, I'm leaning towards like a fungal/mold thing?!? I brought some greencure and will try it first.

What kind of water are you using?

 

[Creeperpark]

It looks like your EC is too high and the salt concentrated in the rockwool is higher than in the plant and it's sucking the water back out of the plant.

 

[flower~power]

almost looks like a bad case of leaf taco ‘ing ? .. if it is that could be considered a climatic condition, maybe too much humidity?

What kind of water are you using?

shitty tap water that i 24h bubble to remove the chlorine

i was thinking the same, ill test the runoff next watering.

The humidity in Rio is crazy, averages around 70, currently its 77 and the vpd is .77. I use push sensors to monitor

That's your problem friend, because it raises your EC too high. If you used RO or Rainwater you could cut your EC in half. Rockwool demands quality water or your plants will suffer.

This is magnesium deficiency/lockout, because the plant is in early flowering and is using more magnesium (and nitrogen).

The reason why this is magnesium deficiency is:

- the dark blue coloration of the leaves
- the thickening of the leaves
- the affected tips of the fanleaves
- the ribbed effect or interveinal chlorosis
- the canoeing, also known as 'praying for magnesium'

At first glance, it looks like a non-mobile nutrient deficiency (i.e. iron), however that is because most of the lower fanleaves have already been removed.

However the reason for the magnesium deficiency, other than the plant being in early flowering, is likely that there is lots of insect damage - most likely mites.

Welcome to Mata Atlantica https://en.wikipedia.org/wiki/Atlantic_Forest
Sorry mate, 70% humidity is the lowest of the day. At this time when I am writing this humidity in Rio is 96% and will be like this all night every night. At midday is the lowest humidity level
What is crazy is to grow lat 50N genetics at this environment and expect to have good results.

I am curious about the permission you got. What is this "medicinal" permission? Who is issueing these permissions? What they do allow you?
Is it for CBD plants? Or you can grow anything you want? Because outdoors with proper genetics you could have 30 1kg plants and who cares if it has a high or not or if they are medicine or not. 30.000 grams of weed is a lot of money at Mata Atlantica, you could compete with the Comandos selling paraguayan brick at 1u$s gram
Local growers get these permissions so easy as well? Because if they do the whole country would be planting weed

Tap water has good minerals. Just leave the water 24 hours to evaporate the chlorine and use it
If you dont like the tap water, gather rain water

About the approach to grow weed in Mata Atlantica
You can do as illegal local growers who dont get any permissions do and grow the local landrace which is a lottery ticket, polihybridized weed with a good dose of hermies thrown in the mix, not any different as what you get from the most reputable seedbanks as "landrace"
Or create an environment where to grow your lat50N indicas because Rio is not Maine nor Cali
You would need to spend a lot of money in dehumidifiers if you are intending to grow under lights
But it doesnt make any sense to grow in Rio under lights, you can grow weed all year round with indica hybrids, the problem is the adaptation to humid conditions
If you dont create an artificial environment and try to grow indicas in Mata Atlantica, what you will get is a harvest of rot and fungus

Grow proper genetics for the humid tropical weather you are in (good luck finding quality for this environment at this canna world!) or create and invest in an artificial indoor environment, but what is the sense of doing this in the tropics?

Note that the genetics from this part of the world, when they reach Usa or Europe finnish at the dustbin, humid resistant genetics jungle genetics with big adaptation to local fauna have same result at usa as the result you get from the commercial Usa or European genetics at Mata Atlantica
All garbage. It is what it is

Thanks for the advise. The Dr that I use for the medical canabs put me on a to a lawyer and with her help we used the Habis Courpus. Once i sent the paperwork over to the judges, I won my permision to grow in less than a month. If your in Rio and want my lawyers info DM me.

Its a lose end your right, i just bought a filter. Arrives on Friday. Thanks for the feedback.

YOU will be glad and blown away at the difference in using RO water. You can expect your weed will increase in quality and quantity after the switch. Keep us posted friend and thanks for the posts.

Did you get this figured out? How are your plants doing?

 

[right]

Is this russet mites?

 

[led05]

Imo yes or similar & nutrient deficiency too, but it sure does look buggy in there indeed

thought this was about .... sick girls... never mind
Got yourself a 60x pocket jewelers loupe? id look for mites
I just started this thread here Pathology "Sick Plants" it needs more photos to help others

in Humid climates without a/c, grow tents with the lights get too hot and humid, even with ventilation. its better to have a big open room with alot of fans and space for airflow. and looking at the leaves its a colder climate strain, not ment for hot and humid environments.
