Brown/White/Yellow Spots - Fungus?

[Jim Dunlop]

I've had this problem my last couple grows with seedlings. It seems to only happen to plants from seed.

Nutes: Pure Blend Pro, LK, Sweet, CalMag+
Temp: 75 day, 69 night, RH 20% (i short circuited my humidifier)
PPM - 400, pH 5.6
Res - 71 with hygrozyme

All plants share a res. Some have NO spots.

Thanks in advance for any help!

Another strain (Grape Krush)

So many talented growers and not ONE can give me any insight?

Not really based on the info you've provided. How about filling out the Stitch's form? i'd especially like to know about your lighting, what kind, how close it is etc........and did the issue start after the humidifier went down?

Also ppms, strain being grown, age of plants, when was the last time you flushed, how often are you checking ph etc etc etc.... Believe me I'm not saying I'm a talented growers but I CAN tell you that talented growers don't just guess based on the most mininal info.......that's not how they got to be talented growers in the first place.

I believe it's just nute sensitivity. Most of the leaves showing discoloration are older leaves and started with the spots when they were in the aero tub.

ph/ppm/temps are constant with my 24/7 meter

light is 400w MH about 1.5 ft away.

Plants are a few weeks old.

Strains are listed above pics. Grape Krush, Purple CindyxWhite Widow

Based on pics and the info provided a suggestion isn't totally out of the question.

lack of air. a bit more ventalation should clear it up.

they dont need a fan usally til they got five sets of leaves.

I can give you a wild ass guess.
But it probably wouldn't help ya.

Or, just fill out the form, ya lazy boi!
Unless all you want is unfounded opinions.

Talented growers don't guess in the dark.
Ya gotta he'p us he'p you.

I'm using R/O. Anything that form asks is already answered by me in this thread. I'll do it anyways....

From my experience pictures speak MUCH louder than words.

I'm guessing you didn't see my 450 cfm 6" vortex in the pic...
