Honestly I think magnesium is the issue here. If your using calmag increase the dose slightly. Try to go by what the manufacture recommends. If your not using calmag get some and use it 👍 Remos magnifical is brilliant, good luck bro 💪

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

Lower Leaves Yellowing
I have noticed that a lot of lower leaves are turning yellow. Theres nothing special going on, it just fades from green to yellow evenly. I am feeding it Veg nutrients 3:1:3. So it can't really be a Nitrogen deficiency right?!

Help calcium deficiency
I think I have a bad case of calcium deficiency? This started shortly after switched to 12/12. I added 1/4 tsp to a liter of water 2 days ago. I’m not seeing improvement. Am I right ? Will the leaves turn back green (how long)? Is it something else? Will it die?

As you can see, the first two plants look quite good while the last two leave something to be desired. The leaves on the back left are curling downward and
and yellowish at the tips (in places). What could be the reason? I ordered some epsom salt to try it out (sulphur). I grow in floragard proffesional growmix (grown in lightmix from biobizz) and have so far only “fertilized” with supervit, otherwise only pH-adjusted water. pls hlp

Yellowing copper leaves late flower
Harvest is coming up soon and I have noticed some of my leaves mostly the bottom but some on top also have started to turn yellow with brown/copper spots. I believe it is cal mag deficiency, will this mess with my yield or quality of the bud?

Yellowing Leaves, Red Stems, Brown patches.
pH is correct - run off ph, too. These are 2 out of 4 plants who show these signs. I gave less Flowering Nut in fear of giving too much Nitrogen. Cal/Mag is in use. Is it Phosphorus/Potassium def? I just flushed and gave BioFlores in recommended dosage again. Thoughts?
