I'm growing Glueberry Auto's using an Autopot system with coco coir and Canna A/B at 52ml each, Bulletproof 3.5 ml, and CalMag 30ml, all numbers are total dose in 8 gallons of H2o. Using Kind K5 XL 1000 @+/_ 30 Inches from tops, RH btwn 35 and 60 (swings are tough to control) PH 6.26., PPM now 628 down from 770s (no overt signs of nute burn noted)

These girls are approximately 7 or 8 weeks old at this point and are showing wonderful flower production but despite my efforts to adjust ph up from 5.5 where it normally sat, to 6.2 to open it for calcium have only shown a continuation of these Brown spots which 1st started on the lowest leaves and are now showing towards the top of the plant...reservoir Temps are good btwn 62 and 70F and have a root mat to offset floor chill set at 65F. This is my second attempt at Auto's and is way better than the first run which was done remotely and failed miserably! I could use some direction and added some pics...T p.s. pic shot through safety glass lens! Thx for looking.

It will have to wait a little while as they are scheduled to go to sleep soon and I will try and snap a shot shortly after the light goes out so as not to be overly disruptive to them.Thx for getting back P.S. I knew I forgot the PK 13/14 @ 27ml and the solution is in 9 gallons not 8...

You might have light burn, depending on how much area that 630 watt light covers.
Autos might be more light sensitive, in part due to the longer hours of light we usually give them.
From what I can see, it's mostly areas getting direct light that are affected, and then probably only the most susceptible get burned.

30 inches seems pretty high, but I usually keep mine even higher to avoid burn.
Raising lights 6 inches for a few days might result in happier leaves.
Even if that's wrong, little harm will result.

I had considered that will now have to modify my hanging system as I am pretty much about 1' from the top of my 7' tent.

marbling--inside of leaves can be a sign of lockout.
