Magnesium deficiency?

[Kinezokyprios]

Add a spoon of organic cal mag granules (crushed sea shell) in the medium before planting the seeds. It will start dissolving with the first full watering and it would last for around 30 days. Then you top feed one more spoon every 30 days.
But this is the solution if you are desperate and panicked or you have a real deficiency. If you water with tap water and you use nutrients like biobizz then it is almost impossible to have a real cal mag deficiency. All you have to do is adjust your ratio of temperature/humidity.
If you are in late flowering you must have 25 degrees celcious and 40% humidity, this can cause calcium to move more slowly in the plant, but has nothing to do with real deficiency and magnesium already exists in the medium. Since plants are more thirsty and you water more often, both will be soon in balance.
In early and mid flowering just make sure that you have 25 degrees with 60-65% humidity and both calcium and magnesium will be fine.

Great info thanks because I've read a lot of conflicting information on this. I fed my Zkittles OG at every other feed with biobizz algamic and the plant was very green with perfect leaves up until very early flower and added no calmag so I'm sure your right that there is no need for the calmag supplement.

I think I had the humidity too low mid flower for my first couple plants and this one I'm sure it was hovering between 50-60% closer to 50% will add a bit of humidity next time around.

Thats great to hear I was looking to try and avoid using chemicals and just stay conpletely organic but with the first two plants having fluffy buds I was under the impression that you needed to add the chemicals to get dense flowers. I will see what this biobud does hopefully adds some density.
