JERgarden
started grow question 6y ago
It seems this girls is showing a magnesium deficiency? If this is correct, should I increase the cal-mag doses or should I just give her a high dose of epsom salt? Appreciate the help!

I'm not really sure what that is but it's not magnesium. Perhaps it's some kind of overdose/lockout or over/under watering., 🌱👍

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower
The odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

CalMag deficiency?
I have had it 2 times in 7 weeks, the leaves are bright orange. I'm adding now 1,5 times the normal amount of CalMag. Starts with small spots in the middle of the leaves and progresses towards the veins. Always happens in the middle of the canopy Am I overlooking something?

Leaf colour help. Hi all. I think there may be a problem with the new growth on my plants. They are 10 days into flowering 12/12. They look like they are too light. They veins are much darker giving them a stripey look. I had the light very close to them when it started. ?

Yellow stains on bottom leaves (indoor grow)
On day 25 yellow stains have appeared on the bottom leaves of two plants (critical 2.0). We don't know from what these stains are coming. On one of these plants, some leaves have also started to develop white dots. Spiders maybe ? Thank you.
