Leaf discoloration

[Phychotron]

Just started using the autopot for the first time, but i've had this same problem on other plants, where a portion of the leaf dies completely but the rest is usually fine.

Pictured here it's just starting on a plant that's been in flower for about a week now. Thanks

That does look familiar. It appears viral to me, but let's see what others think. I would treat with aspirin. One 325 MG tab per gallon of nutrient solution. I had something similar, and never could get rid of it.

///at the firsts look i thought ur leafes turned red.. lol ... such genetic differences are quite cool ^^



Had the same cause of dropping RH and to much venting -> burn. Could also be that some water drops evaporated there.

You have temp/rh measurement at leaf surface?

I dont know much about virus infects like tmv or something.. but what I know is that they get into your room with strange clones. So if you havent got any clones its probably not viral

Those are pretty good guesses, I was thinking the same as well as possibly just a hot spot on the light. We have em all the time and learn to spot em and move plants around accordingly.

Room: 4x4 tent with a small oscillating fan in the corner blowing on the top of the pots. 8" fan/charcoal filter that's running constantly on low. another 8" fan cold air intake, through a prefilter (dust, pollen, etc) using outside air, hooked up to an automatic speed control with day/night temp set to 80/75. Lighting is two 240w blackstar led, one 500w blackstar, t5 4x4 on the side, 3000k bulbs on order.

the speed control on the cold air intake keeps it pretty nice in the day when the lights are on, but the night time gets a little low with the one 8" fan that runs constantly, ~63º. I plan to swap their day to the a.m in order to draw warmer air when they are sleeping.

Humidity the past few days has been between 30-50%

The autopots are hooked to the res with a 45lpm air pump, but i just found out my cheap timer is sticking on the pin and not spinning at certain points. I plan on using the air dome in the autopot to pump air directly into the root zone.

The mother plant, notice the leaves have the spotting, but I also noticed this plant was looking a little saggy, so I stopped watering and it took awhile to suck down the water, so then I flushed it and drilled about 20 holes around the bottom (cheap walmart container--soon to be thrown away) it's looking much better now, but it did have some of the same things, where a rusty or brown spot will just randomly occur and dry out.

Week two starts today and I was going to top off the res tank with just water + big bud. Surprisingly these 4 plants are thirsty, 50/50 coco/perlite might have something to do with it.




I found this seed that might have been a freebie with my brothers order, and its smelling nice, buds look like they are going to be great, but no where near as extraordinary as the GDP just a week ahead. I'm not keeping a mother around, but I would like these to have the best opportunity possible.

The Blackberry also is showing some strange discoloration, but I was told to expect strange things like that from this plant, that and leaf curl, which has been minimal. It's been in flower a week and a half or so

I think it could be a combination of a few things--I see a nitrogen toxicity in combination with a phosphorus problem, along with a possible issue with VPD. If they're cold it makes everything worse.

The blistering and twisted leaves/brown spots/holes in the leaves sure look like TMV or similar virus. Pictures look like my old sick plants.
