Hey all, I'm a new grower looking for some troubleshooting help - I have 8 plants, 2 strains (4 each), majority are looking great but 2 of 1 strain have been showing some brown spots for the past week. All others are green, perky and happy - the ladies with the spots seem great otherwise as well. Based on my novice research it looks like maybe a calcium deficiency(?), I made a few tweaks during their watering today incase that was the problem. Details:
Soil: Fox Farm Ocean Forest bottom 80%, top 20% 50/50 FF Ocean Forest/FF Light Warrior.
Age: Seeds planted 8/6, sprouted 8/9 (25 days above ground today).
Lighting: T5s for veg, 8 bulbs, 4', 18/6 cycle.
Watering: ~pH6 water until today (did not have a digital tester previously), added recomended dosage of Superthrive on 8/12 & 8/17 (few drops), and they received their only dose of nutes (FF trio) on 8/28 (20 days above ground) at 1/3 recommended FF dosage (plan to do 1/3 for week 3, 2/3 for week 4 and 1/1 week 5+).
I just received a digital pH tester this week, seems like initial watering was maybe a tad lower than 6 (~5.8?), so I raised pH today to 6.4 for this watering. I also added some Cal Mag at .25 oz/gal (at the recommended dosage, 2 mL per L). All plants received the same watering with Cal Mag today despite 6 plants not showing any spotting.
This strain is "Pura Vida" courtesy of Oregon Green Seeds. They are NOT feminized. Strain:
Hollywood Pure Kush/Appalachia

Can get more close ups as needed, thanks!!
