Hello,

I'm currently 3 weeks into veg and one of my plants has spots on the leaves. I've read through the sick plant forums and i'm still not sure whats going on, i have a few ideas i've narrowed it down to, but i'm curious what someone with some experience would think.

These are my conditions.

Soil FFof
400 watt MH conversion bulb
Fox Farms liquid nutrients (may have nute burned slightly a week ago, i'm not sure if this information is pertinent in helping the diagnosis)
Ph at last test was around 6.0-6.5

The problem started appearing 1 day ago, it only appears on the leaves of one plant, and its only on the lower fan leaves, the upper leaves and new growth don't appear to be displaying symptoms.

Any help would be appreciated, thanks in advance.

It could be a deficiency of some sort. I hate diagnosing nutrient disorders because some look a lot like others. Try to give as much info as possible. What type of water, strain, temps, humidity, etc. Could just be that plant also. I've noticed some of the lower leaves on some of mine look like that. I usually don't worry about it unless it spreads.

The leafs closet to the soil usually turn that way because the soil is moist and its keeping the leaves too humid and starting to create a fungus, I would trim them off and cut your losses.

temp is between 78-82 light on around 60-65 light off

humidity stays around 35%

its just bag seed so i'm not sure what the strain is

Water is reverse osmosis water

I'm guessing it's a magnesium deficiency. I use r/o water as well and have had trouble in the past with magnesium deficiency. Try using some cal-mag.
