I have two 1ks. the plants are getting about 60 watts per square foot. After the deficiency started i foliar sprayed with a cal-mag solution. They were moved away from the lights until they appeared dry.what kind of lights do you have? And did you spray and then let the lights hit the plants with liquid all over them?
im still leaning towards some kind of disease. Only keeping them to see if the problem can be reversed. i have some Chocolope kush and White Widow beans i just popped. Im hopping its not some crazy environmental condition. My day night thermometer/hygrometer says im solid at 75-80 degrees 50% humidity. 24k shinco mini split. 70 pint ge dehumidifier. Co2 is 800 parts cppm-4 bottled. i have plenty of air flow.It looks like plants that were in the dark for a week than subjected to intense light or it's spray that was cooked on the plants. Other than that, no clue and would scrap em and start fresh...something isn't right and it's prob your environment....live and learn.
im sorry. earlier when i said "im still leaning toward some kind of disease" I misspoke.. read through a thread by silverhaze and believe we were having the same problem. Fusarium. i was actually going to ask SH where he sent his plants for testing.I'm really interested to know what this might be. Thx for keeping them alive and sharing with us. I basically though you got your lights too fast too close. But it seems like there is something else. Most micro deficientes start in the upper part of the plant. There is always a possibility to overdo some nutrients and get deficiency symptoms, but i highly doubt that this is your problem.
ok good luck...I only ask because I was having problems for months on and off and couldnt figure it out until one day last week I looked back into recycling ac and dehuey water and I say looked back into it because Id looked before and saw people werent having problems at all recycling into the rez????? This time I googled specifically for problems caused by recycling the water and found this blog...http://everydaygreener.blogspot.com/2008/06/dehumidifier-water.htmlive come to the conclusion its not my water at all....... placed four clones in my troublesome flowering room under t-5s 18-6 light cycle. another four were moved to a new veg room. both fed with the same ro and nutrients. plants in the room have the discoloration. my other four are fine
