powdery mildew for sure. not sure on red spots. sounds like its a number of things in my opinion. when you get deficency going, other things go wrong. also, most ph a little lower...i am in soil, and ph 6.3

where do u see powdery mildew that is light yellow u must b seeing in the pic there is no gray or white on the leafs and I have looked with 100x scope and no bugs or molds

SPLFreak808 · Sep 21, 2015

Looks like a possible Mg/Ca def. If only my phone would load these pics properly though!

what ever it is it is moveing fast

I believe its either ph or calmag deficiency. Get a decent ph meter, and make sure its good. Also add some calmag to your nutes

is it ok if I give them nute and then next water give more nute I know u want to get pure water in there but seems like I need lots of nute

CalMg is my guess

Are the spots dry?
Do the leafes wilt or die at a certain point?
Could be a problem in the soil. Where you got ya soil from?
The ph is still ok for soil.... rainwater is about 7 here too and never observed a nute lookout when I wateted plants with it. Wouldnt go lower than 6.5 in soil myself. Check a nute uptake sheet related to ph and youll know why.

Give them nutes. Start half strenghts. Go get some calmag
use it too but not toooo much. After that chech if you still see it in new leafes too.

Just my two cent

I use coco loco soil I gave them hafe them full it don't seem to have stoped but sure looks like it slowed it down and the leafs r dry and dead only on the sports it starts with tons of lil spots then group togather and make huge red dots then the leafs dies but the leaf that is touching the leaf is still some what a live just the fan blades died

Calmg deffeciency has done that to me before. I get spots, that turn to dead tissue. I hit them with calmg and it fixed my problem. This really shows if u run RO water. But I'd hit them with a full dose of it next watering.

Yes looks like calmag is the solution.
I would try it for sure.

Peace

Edit
I thought your in soil.... but coco needs a lower ph than 7.
About 6 should be fine.

Lower ph + calmag one day
Next day lower ph plain water
next day lower ph + ferts

its the foxfarm soil plants love it tell they in flower for about 3 weeks

Calcium def. and ph fluctuations with phosphorus def.. http://www.growweedeasy.com/marijuana-symptoms-pictures

Dunno where you life at and if its possible for you to walk in the next gardening store and buy a calmag product. Its cheap and often used for growing tomatoe and stuff like that. You can buy it by the kilo here and it lasts ages. Over here it looks like perlite but its heavier.... you can place it on top of soil for a permanent supply
... or you put the amount they recommend on the back of the pack into water wait a hour or so till all is broken dow then stir well and water your plants with the solution for faster results.
the K in it is fine in flowering so no problem for you to use it.

I guess it was the K in your fertilizer that helped ya plants already..... but I would go for some calmag

Gbuddy · Sep 28, 2015

Keep in mind if the base of your medium is coco its very low in nutrients and you should always have a good nutrition with every watering or at least every second watering.

You plants suffer from completly having nutrient deficiencies of the whole spectrum at the moment because you havent provided good nutrition at all.

No offense bro but thats it.

Hopefully your plants recover.
you will lose the leafes that already have big red spots. But if you follow the advice given to you in this thread you can maybe partly rescue some of the harvest.

Why you didnt use fertilizers earlier.

we where very busy and only had time to give it store water and my ph meter sucks soooo bad I need to find one that don't take 20min to tell me the ph and I have used calmag on the plants when I first seen the dots but im told calmag can ez kill a plant in flower so I been giving them 1/4 of the doss

That doesn't really look like PM...

If the pH of the medium itself or the water is too far off, your plan't physically can't uptake nutrients.

CalMag won't kill a flowering plant

It shouldn't kill them, maybe cause the buds to be airy, but I'd give it a full dose, they look like they need it.
