Help a Lass out, purplish splotches

[Chronic Chrissy]

Ok I just checked on my plants and I HAVE A PROBLEM.

My plants are 53 days old, and 17 days into bud in 3 gl pails. They are taking more water more often, We went from 3L every 6 days to 4L every 5. Yesterday I watered full feed with Big Bud(since you only use it 3 weeks and it cost so much and I have so much extra) The carbo load, Cal/Mg, and the three part nute system. I'm just using their lite feed though. The pH was at 6.5 going in and soil pH is 6.5.


One one of the 4 taller plants, 2 fan leaves are affected. It starts at the tips and is inbetween the veins. It turns splotchy dark puplish green then affected area contorts as it curls up and dries dark green, not much different than the original green, but crispy.

Any ideas on what this is? Please help.

its a little difficult to pinpoint your problem without a few pictures. In the mean time refer to this site: Grow Marijuana FAQ, Cannabis cultivation - marijuana growing tips & photos, there are a ton of pics there and I am sure you will be able to see your problem in one of them.

Molybdenum (Mo), maybe?
International Cannagraphic Magazine Forums - The Complete guide to Sick Plants,pH, and Pest troubles!

Pics aren't turning out and have guests over. I'll try again in a bit.

Low temps? I had a late blooming outdoor plant do that once. Ended up with weak, horrible tasting bud. If you smoked enough you'd end up stoned, Might be lack of oxygen to the brain though.

Temp is 77 during the day and 64 at night. Great ventilation. All the plants get the exact same everything.

how old are the plants, maybe you need to flush them
