Crazy Plant Flesh Eating Disease, Please Help!!! Pics attached

[KreegDaddy]

Growing in 5 gallon buckets using Basement and Happy Frog 50/50 soil mix. I water every 4 or 5 days days since the soil mix seems to retain moisture for quite a while. I have been fertilizing with "Alaska Fish Fertilizer" and am giving a 20/4 light schedule with a 600 MH. I Ph my water to 6.0 after I add the fertilizer to it since its way too low after I add the fish fertilizer.

These pics are happeining on two of my plants right now, has any one seen this or know what it is. Its on the top leaves and some lowers too. I'm sure its not bugs, it seems like it has to be some sort of deficiency.

Please send any advice or thoughts, I dont want to lose these... Thanks in advance!!!

Potassium(K) Deficiency. Add some call-mag too. Aides in the uptake of (K) It could be too much Nitrogen in the soil already. See Chart Below

Elemental Interactions
As one might imagine, nutrients often do not work alone in their effects on plant growth and development. Quite often, an excess of one nutrient can cause a deficiency of another. This effect is called nutrient antagonism. For example, an excess of potassium in the soil solution can interfere with magnesium utilization, and in effect causes a physiological magnesium deficiency even where the the soil supply of magnesium has been shown to be adequate. Another common antagonistic relationship is that of excessive phosphorus and its effects on zinc, iron and copper uptake. Some common antagonistic relationships are listed in the following table.

Fortunately, nutrients often work together in many instances to enhance one another. For example, use of readily available water-soluble phosphorus enhances utilization of nitrogen, and vice versa. Most nutrients are more efficiently utilized when in proper balance in the soil solution.
Using TotalGro water soluble plant foods at rates appropriate for the species being grown allows the grower to maintain the plantings at optimum growth rates for maximum marketability and profit. All plants grow best within their own well-defined nutritional boundaries. These boundaries are species-and-variety-specific, such that when a particular plant is exposed to either the lower or upper limit, plant vigor and performance falter. This property of plant response to nutrient supply is better known as the Principle of Limiting Factors. Basically, this principle says that the level of crop production can never be greater than that allowed by the most limiting essential plant nutrients.

You have some kind of insect or caterpiller eating on it. If it's still around should be easy to find. But might have eaten a bit and decided he didn't care for MJ

Looks like caterpillar damage to me.

That definitely looks like some sort of insect that made it's home on or very close to your plants.

thats bugs.

probably earwigs, they dont particularly like dope but will nibble any foliage.

take an old newspaper, get it wet, just a little damp, and put it near your plants. turn the lights out for 12 hours and then check the newspaper. i bet you find earwigs.

also look on the underside of your pots.

Thanks for the replies everyone. I looked real good for any caterpillars and other bugs but only saw a couple of blac flies. I dont think that they wold eat my plants. Also checked under the buckets for any sign and didnt see a thing. I do think you guys got me on the right track though. It seems that if it was a deficiency that the entire plant would show symptoms. The overall canopy seems to be doing pretty well.

Does anyone have any thoughts to add to HappyMans post concerning a possible potassium deficiency?

They look pretty green and waxy looking to me. The 3rd pic in the 1st post looks like a twisting leave. I think you should slow down on the nutes for a while; maybe until you start to see a yellow leaf on the bottom somewhere.

ph and heat.

Potassium deficiency does not make sections of the leaf fall off. Something obviously ate some leaf. Critter is probably long gone.

i would leech with tons of water if there is any concern and start back up with half nutes in a week. i bet your plant will respond quite well.

Well, I'm pretty sure I found the culprit. I dont know what this bug in the piture is but he died today. Also, a fuzzy green and black caterpillar met his end today. The caterpillar wasn't physically on the plants, but directly under them on the concrete. I sure appreciate all of the replies and i guess Ill justhave to be on my toes a bit and keep checking for these rascals.

Peace
