I don't even grow in soil, I am growing in in a hydro system. I use Fox farm grow big liquid nutrient. The spots started appearing after I started using it. I feed at full strength with 3 tsp. per gallon. I have 3 26 watt CFL's a total of 72 watts. Not much., but it works for now. I don't mist my plants or anything like that. My ph is somewhere between 5.7-6.0 hydro is supposed to be between 5.5-6.3 or really close to that range I believe. I can't get any pics right now, because my camera is not working, but you have to believe me when I say. They look almost identical to the pics you posted in the first post.

So nothing to say I guess? I am thinking Nitrogen toxicity because I have found no bugs, and the nutrients I use are fine. I'm thinking that tomorrow. I will flush and only use half the strength I have been using. See what happens from there.

After chatting with my senior and good friends on the forum (Lime73, Matthebrute, Mistyrifs and bkbbudz - much respect guys) regarding my/our problem, there is definitely a nutrient toxicity. In my case there is a blockage of the roots due to lack of Calcium and too much nutrients or the nutrients are not absorbed and causing toxicity to the roots and from there up. It was a lack of Mg as well. This dots are appearing from the middle of the plant and making there way all over after. So usually a lack of Mg is manifesting like that. But I guess all the problem started due to the Ca deficit. I had to wait until today for my flush cause I ordered a Ca solution from Canna from internet and when I am doing the flush, I will need after all the solutions. So...flush until soil is clean, and after nutrients + the last 3 gallons of water combined with some epson salts(for magnesium) and the Ca solution ( I need to see the bottle for instruction first).
If you are sure that you have the same problem, you can do the same. I trust this guys with the life of my plant, it's not the first time they are pulling me from mud and they've been right with their advices.
Sorry I didn't reply earlier.
P.S. check my journal, the last pages is all about this problem https://www.rollitup.org/grow-journals/496280-perkeles-growing-journal-first-plant-30.html
All the best and tell as how it went. Be aware, after this procedure with the flushing, the plant will be sad and droppy. Not to worry , she will recover in one day under the light.

I ended up flushing and feeding a very low dose of nutrients. Probably an 1/8 of the strength. Going to wait a day and see how it responds. If it gets worse. Looks like ca mag for me.

Well that didn't work. It's getting worse. I think I have it figured out though. After reading this page. http://marijuanacannabis.wordpress.com/2010/05/21/nutrient-deficiency-magnesium-mg/ I have been adding lime to my water to lower the ph...so stupid..in the section of causes of magnesium deficiency it says that a lot of lime in the tap water can cause it...I was/still am using quite a bit of lime. This makes more sense to me than anything I have read or researched so far. I am going to the hydro store today and getting some ph down and some type of solution for magnesium. Hopefully I can get this under control. I think this may be why my plants have yet to flower after being on 12/12 for almost 2 weeks.

For Mg you just need Epsom Salt, you can get it from any health shop. I bought 300 mg with...4 euros or something.

So I would just add the epsom salt to my water with the nutrients and ph down?

yea, it's about 1 full spoon per gallon of water. I added in mine some Canna Calcium as well, cause more likely there is a Ca deficit in mine.

I just bought some epsom salt. So say I have a 1 gallon reservoir, I would just go ahead and add one full spoon?

I'm sure you are getting good advice from those much more knowlegable than myself, however, I did want to comment how your leaves remind me of this post: https://www.rollitup.org/outdoor-growing/453514-guerrilla-growers-nightmare-leaf-spot-4.html
post #39. I hope you are able to get it sorted out... oh yeah, you can get this stuff indoors as well, have you heard anything about this stuff being in your area?

I went ahead and did that earlier. Have you done this perkele? How are your plants doing now?

I flushed it and gave it both Mg and Ca. she is stable, no new spots/dots, but the damage was done, so the leaves are not getting any better. it's a slow death, but at least I have about 2 weeks to go and she'll make it.

It's not mg deficiency. I added the epsom salt yesterday. My plant looks worse today. It has to be Ca. I don't know any way to get ca into my solution other than buying cal mg, but I don't have any money for it....

what I did , I flushed it cause in my case there were a bit too much of thous nutrients(Miracle gro) and after I gave some Mg and Ca. Now it is stable, it's not getting worst but it's not getting better. Try to go to a pharmacy and buy some Calcium Lactate (with no other additives in it) and just dissolve it in water and give it to the plant. I don't know if other agree with me on this but I would do it. Depending on the country, my Canna Calcium cost me 25 euro. In other countries you can buy it for 3-4 euros. Some are using dolomite lime , only thing this is coming only in huge bags (25-40 kg)...
