No, never.

Thanks so much. I'm a little confused about the whole litre part though because I use gallons. How much cal/mag per gallon do you think I should use to treat this problem? I was giving 2 teaspoons a gallon for a while.

If it's spider mites shouldn't there be webbing all over the colas?

???

15 months or years? Does your cal/mag deficiency normally look like that? Do u use R/O water and add cal/mag in those first 7 weeks?

Ya its really confusing and hard to tell if its getting better, staying the same, or getting worse. I wish I knew how to truly test the pH of the soil.

It has very little if any peat moss at all. I forget what its called I think its made by a company called Aurora. It worked great up until flower....

No i'm not. This is the first grow i've done NOT using FF. Thanks for the help man.

If pH is accurate, how much cal-mag do you recommend per gallon?

I've checked for mites and I can never find any. What is the BEST way to check the pH? When I try to check the runoff I run into trouble because I can never get an accurate reading on plain R/O water! The guy at the water store that I go to says he's sure it's 6.5 but my meter can never get a...

Oh I see.. I'm not really following any specific nute schedule but I try and keep the feedings no higher than 1000 ppms. I'm fairly confident the ph of my soil is anywhere from 6.5 - 7. These problems always start develop RIGHT when I switch to flower. I use R/O water with a ppm of 10. I feed w...

I don't have one right now and the light is off so I can't go take one. That's the only problem i'm having though. At least half of the leaves are covered in these tiny yellow dots. The pic I attached is one of the worst looking leaves on the plant. I thought burning was supposed to show up in...

Does anyone know what can cause tiny yellow specks to develop on the fan leaves. This seems to happen to me a lot right when I go into flower. I can't tell if its over or under fert. I am not on any specific feeding schedule and I'm pretty sure the pH of the soil is anywhere from 6.5 to 7. Any...

This started showing up on the larger fan leaves TWO days after moving plants from veg under T5s and into the flower room with a 400 watt hps. I'm guessing it has to be either burning from the light or some sort of deficiency. Any help would be great!

Are you 100% sure tho that this wasn't caused by the soil being too rich? It truly looks to me like those leaves are burnt. Or maybe I just can't tell the difference....

Thanks bruddah!

Cool, thanks man.

the pH of the soil is 6.3-6.5. So I don't think that's the problem.... I was trying to go organic without adding nutes to the water, so I was using ONLY tap water for a long time with a ph of around 8 (and I live in San Diego where the water is extremely hard) so excess calcium is definitely a...

Yes thank you. That is definitely the start of it in pic3. I will try the lime next time for sure.
