Okay here is an ICE strain 4 weeks into flowering. The spots are only found on older leaves and towards the bottom. But today the top newer ones start showing little signs of it. Here are two pics, one showing early stage, one showing the worst. My other plants and straings around it are fine and not showing the same at all. Soil grown in Fox Farm Ocean forest and Happy Frog(started in Happy frog, transplated before flowering into ocean forest) Used very small doses(1tsp-3tsp per gallon) of nutes every other watering. Using a 1000w hps. Temp in room is at like 72-78 light on and drops to 59-65 at night.
Weird Spots, Tip burning. No Visible Pests HELP

Nute burn, calcium deficiency or other problems caused by incorrect and/or fluctuating pH levels. That's what I think anyway lol
The fix for this on Plant Number 1 that showed this first was a flush, and then let dry, switched to RO water and watered it, let dry, then watered with a half dose of clearex, then finished the flowering cycle out with just water when soil needed it. Overall yield was very low an oz or 2 at most. Switched all plants to RO water and growth was stunted and delayed but after two weeks now things seem to have picked up again. RO water is the only way to guarantee your plants are only getting what they want from your water.

That is def. your PH being off. I had exactly the same problem with exactly the same spots on the lower leaves and such. Check that PH before adding it to yor girls!!
Leaf spot fungus. Horrible shit.
If you got any garlic crush it up, mix with water & foilar spray before lights off,that will slow it down maybe enough to get to end of flower. But LSF spreads from plant to plant so, act accordingly.
To completely eradicate it, i only know 1 thing that works 100% Webby's Essence, AKA Plant Magic essence.

I have an outbreak that i'm treating, right now in my clone cupboard. Effecting my White widow & thai/Haze.. All my NL's on the other hand are spotless!
So i mixed up 2l of Plant Magic essence & dipped the clones in them to cover the whole plant & will repeat this again in 5 days. Pored what was left over into roots. Should be gone in a week.
Spent the rest of day disinfecting & improving ventilation in clone box.

Did that fix the issue. I think i am dealing with the same thing! please let me know if that worked got you. I just made a new clone room and think that there isnt enough air movement which game them the ability to germinate and take hold.
Thanks
