This is my first ever autoflower run. I've been having a few slight issues. One has been some extremely light green new growth. Which I'm figuring is a local of nitrogen. I'm using totalharvestorganicsoil mixed with cococoir and perlite to fluff things up. The autos are 1x northern light 1x whitewidow and 2x Amnesia haze. I have also had some ph issues. My water her is utter crap and I've been working to keep it under control right now I water at a PH of 6.3 but last week I Ph'eD to 6.5 and tested my run off at 7.1.

Using a 135watt qb288v2. I'll have 2 more in a couple days. Lights at roughly 19" from canopy. Temps stay between 67-75. Rh below 55% right now.

Anyone have some suggestions here? I'll try to upload a couple pics. I have two photos in this tent and they're doing great. Almost no issues at all

If your going in 6.5 and coming ount 7.1 your around 6.8 so 6.3 in would be better.

I'd try and get my humidity up during veg.

And they really look hungry like they need some nitrogen.

I'd agree. However I'm not sure if it's because of a lock out due to PH or if I'm actually lacking in the soil right now I have how ever lowered my Ph to 6.3 this watering. I don't feed cal mag yet so I'll be adding that to the list as well.

Should I consider using a nitrogen heavy nute?
 
I would add some nitro to your feeds. If you can swing it get a good soil pH probe I like the accurate 8. Your pH doesn't seem that far off.
 
Cal mag needed from the start, or very close to it.
You said your water is crap, have you pulled a report and looked to see what's there? My ppms weren't too terrible, just under 400, but it was almost all salts, was locking up everything.
I ended up with an RO system.

Was trying to find a free report online but looks like I'll have to take my a sample in.
This was the site I used to check
https://www.ewg.org/tapwater/system.php?pws=MI0004098

Or should I just invest in a TDS meter?
 
This was what I was sent today in a pdf from my township. To be honest this is gibberish to me. I have no idea where to look on this chart for issues.

My problems have since gotten worse. I'll take a few photos tonight and show the full scale of the issues

So as you can see. I have 2 photos in the tent with nice dark green growth. How ever all the autos are showing these light lime green areas and then dark green outter leafs. Some of the leads also show rusting which I assume is calmag deficiency. I'll have calmag Tomorrow to feed with.

My next watering I'll be adding calmag and keeping ph at 6.3
I'll also be using my aquarium water as I have a decent eco system going in in there already. Should be better than just tap left out
