Hi i need help im a beginner grower and i seem to be running into the same issues over and over. I keep having what seems to be a cal/mag deficiency but i use cal mag and it doesn’t seem to prevent and or stop the continuation of the deficiency.it seems to happen generally in the 3-6 week of flower it seems to stop the growth of the plants everytime i keep the temps 72-85 degrees and rh around 60-75% it is a tangerine dream autoflower i have another td and it’s starting to get the same spots on a couple leaves

mag lock-out. Happens to me to, and tryin to get it to not happen. and RH to high, 50% max at this stage bro. Your night temps must be more then 65F- and day temps must be more then 75F.

When we run LEDs, its almost certain that you need a mag supplement, and 1G per gallon of Epsom salt is a must, pretty much thru the grow up till last 2 weeks of chop.

When we start to see these problems, its to late. And then we start hammering them with CAL-MAG, but an abundance of CAL mixed with high concentrates of Potassium and phosphorous for flower, will lock-out Mag uptake to a standstill, which seems to be happening.

Flush 3 times pot size, let dry out, then 1G epsom per gallon and continue regular feed.

this is why its good to flush every 2 weeks, with PH RO water so a calcium buildup doesnt happen, and the Mag is uptaken when it needs it.

The LEDs consume Mag like crazy, so that is a pathway that needs to be open effortlessly thru the entire life cycle of the plant.

Good luck man, hope that helped. Its seems to be an issue ive had many times myself.

its looks to be about done to be honest. And its so far damaged, Id flush and get on to the next grow. How much time you have left for it?
