You can google cannabis leaf problems and pull up a chart which will show you..my charts are on my laptop and using ipad this am.Sorry I dont know what has happened with the pictures there.
What's your nute lineup..how much how often?It is the odd texture (you can really see it on the removed leaves) that is throwing me off otherwise I probably would have guessed K deficiency with the dark splodges.
IMO that's prolly the culprit right there..only use nutes specified for MMJ..when they come start at half label you can always increase..in the meantime, you can pick up some calmag and dolomite lime(I use Espoma Organic Garden Lime).calmag RX 1tsp/gal every water including nute water..you can sprinkle dolomite lime 1TBL/soil gal..usually u sprinkle in the soil to mix it up..you can get both these at Home Depot..this should start u on the right track.Up until now I have been using a seaweed extract that my girlfriend uses in the garden very effectively, I have diluted it with water and added a good squeeze when I water the plants. I am pretty sure it isn't nute burn as I flushed the plants then did not use any nutes just plain water for a week and the problem just got worse. I know this isn't great but I have ordered advanced nutrients micro bloom range that should arrive soon.
Unfortunately magic has never been my strong point I guess Im doomed then, how can I prevent infestations in future cannabineer?I suspect nargles are behind it. cn
It was a standard soil for growing veg cost me £5 maybe. I am doing this on the serious cheap as its more of a mini summer project and the only grow I can do for a while. The whole setup (inc seeds) has cost me around £130 so as you can probably guess a lot of my stuff is pretty basic. I got recommended to buy epsom salt as I can't find anywhere to get hold of calmag in the uk (we have a lot of calcium in our water anyway so hopefully this will balance it). The seaweed worked great for veg but now it has started to flower I believe you are right about just not having the right nutrients hopefully what I have ordered should sort that out. What is the lime for btw? So you think this is a nutrient problem not fungus based as obviously if it is fungus I need to get some antifungal very quickly before it spreads any more? Thanks for the advice.
More than likely a phos (P) deficiency, looks very similar to the leaves shown here: http://www.growweedeasy.com/phosphorus-deficiency-cannabisIt is the odd texture (you can really see it on the removed leaves) that is throwing me off otherwise I probably would have guessed K deficiency with the dark splodges.
Or maybe it your magic underpantsNone of the soils or nutes I've used have been for MMJ. Hardly ever have a deficiency or over fertilizing problem.
Hey, I've never even met a Mormon!Or maybe it your magic underpants
