Is there any trace of this spotting on the new growth? The reason I ask is it appears that you may have had a problem when those leaves were young and it's just now showing the damage.

Because my grow room was behind schedule, I had to leave my seedlings in peat pots a little longer than I wanted to. They were slightly deprived of nutes during that time and I had sprayed the leaves with water while they were getting light (a real "no no") and some began to show those very same symptoms especially after a few days passed. The leaves began to grow bigger and the damage from the prior lack of nutes and sunburn was more evident, however, the new growth was in good shape. Fortunately I had other plants growing in the same nutrients that were showing no signs of deficiency so I knew it was not my brew causing the problem.

I noticed you have a plant to the lower left of the one displayed that looks exactly like one that I have. The totally destroyed leaf that is spotted and drying up. My plant that is exhibiting this same symptom in it's lower leaves is recovering very slowly, but the plants that grew right next to it are thriving. I discovered that the plant responded better when I treated it like it was still a seedling. Since it's sick, I figured that it was unable to uptake the nutes at the strength an otherwise healthy plant could. So I lowered the ppm to 500 and backed off the watering frequency and moved it away from the light. Two days later the new growth on the sick plant began to perk up and it's been improving ever since. Since the lower leaves were damaged severely, I knew it was just a matter of time before they dried up, so it was my intention to get it's new leaves to grow as soon as possible.

If we could only teach these plants to talk, they'd make our jobs so much easier!

GluteusMaximus Reviewed by GluteusMaximus on . Identifiy the problem ~800 PPM CalMag + FloraNova Grow PH @ 5.6-5.8 at all times -- Skunk #1 -- These are clones under @ a little over two weeks of vegging - I did find algae in the res, so I changed nute solutions last night -- They are under 18/6 cycle -- Plants are getting progressively worse as time goes by. This seems to mainly effect the fan leaves... Rating: 5
