The issue does not resolve itself by simply feeding more N.

If it's not N, the next best culprit is Molybdenum, a trace element that can be locked out at low temperatures.

From the Marijuana Garden Saver by Ed Rosenthal:

"How common it?

Mo deficiency is very rare, but is more likely to occur in color-changing strains in cold temperature conditions.

Symptoms

The middle leaves turn yellow. As the deficiency progresses towards the shoots, the new leaves become distorted or twisted. A Mo deficiency causes leaves to have a pale, fringed, and scorched look, along with retarded or strange-looking leaf growth. Older chlorotic leaves experience rolled margins, stunted growth and red tips that move inward toward the middle of the leaves.

Sometimes Mo deficiency is misdiagnosed as a N deficiency. However, N affects the bottom leaves first. Mo affects leaves in the middle of the plant first and then moves up to the newer growth.

So... the question begs,

Who on the tropical island of Hawaii is growing in cold temperature conditions?

Growing in Hawaii is not for the faint of heart. The phosphoric acid and the gas that emits from the volcano here. is a plague of mold that cleans to the rain it's death for plants. I have had everything as described here. Soptoria purple blight. It can be black too or brown. It comes from the rainforest conditions that we have. I live 1300 foot elevation and at any given time it could rain 3 weeks straight with 99% humidity and just complete mold written death for cannabis. I have tried everything and the best thing that works is OG biowar foliars, actinovate sp once a week foliar as well as root drench. Fusarium is a big one here too. Once again. Humidity, rain, mold, also pests here are x100. I just recently had about a month ago about two weeks straight of rain and I have a new condition with my vegging outdoors, and it's these light circle spots that appear on the leaves, and then after a while they start burning through the leaves and then eventually it'll be a burn mark, and these are only on the fan leaves. If you don't contain it fast then everything is just crap.. hardly any yield, the plants won't grow, it just takes over and also I noticed that these spots when it rains like this, are all over my yard on leaves and most plants and trees in my yard and property. my mango tree has it too.. so it's in the air, it's spore ridden it's Spore transferred.. when we have awesome months of dry weather with no rain there is no issues but as soon as we start having week long dark dredging sideways rain fog shit weather, then everything goes to hell. So the best thing I've found out, it's just too always be diligent with your foliars. with a actinovate and the OG biowar. Biowar has saves my life. It's the only thing I use in my indoor grow, and it kills russet mites and everything every single time with ease... I don't even sweat russet mites anymore or broad mites.. I also use it in my root zone and I have found that plants will be way less resistant to mold pathogens that spread and try to contain them they become way more hearty..
I've been here growing on the big island for 19 years, and I still pull off grows every single time even with the weather bad. Might not be the best sometimes. I don't know how I do it but I do.. all I know is there's nothing you can do once the weather starts getting crappy, that's it..the only thing you can pray for is that dry weather coming when everything clears up..
Also strains. Some strains that we try to grow here just don't work well and they cant handle. Some strains are very resistant, and less susceptible to the Fusarium and blight.. but yeah. Pray for sun. Cause with no sun we are fucked.. I have a saying. " I loose money and add grey hairs when it rains".
That's why I went indoors again as well as out. When we have a month straight of rain I don't worry so much because I'll still be pulling a big run indoors. But before the indoor room it was really really really stressful and hard because it's very nasty weather here sometimes..
And if you are not growing outdoors in greenhouses in Hawaii you're committing suicide.. don't let that spore infested rain touch your plants.!!

Excellent question. HI don't seem to have had very low temps recently. Maybe

- the pots are on the ground instead of on benches?
- relatively cold ocean rain?
- It is winter/very early spring, even in Hawaii

Awesome description of growing in Hawaii. Maybe weed in (occasionally) hot and humid conditions should be pruned like in a chandelier shape like they do in Vietnamese highlands.

Yeah man. It gets wet here..
It doesn't matter what you do or how you prune the plants. When we have months straight of shit weather. Then it's inevitable. Everything goes wrong. And everything mold wise grows. There is nothing you can do but hope for sun. Plants can't flourish in 95% humidity and constant rain.

Nematodes cause balls on the roots. check if you have these. Bi Carb soda helps fight fungal diseaeses

[Douglas.Curtis]

So, not something new or Hawaii specific. Correct?
