Magnesium deficiency?
Fruitgroweranswered grow question 5y ago
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., 🌱👍

PH Fluctuations and/or Nutrient Issues?I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?

They are on the older leaves and they keep getting that faded yellowing starting from the tips. The pH of the run off is 6.43 and they havent been fed a round of nutrients in a week! I thought it was a cal/mag def but they haven't bounced back after a dose. Help please!

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.

Strange coloured fan leaves (3) on one of my 4 plants, maybe some sort of deficiency? Thanks people!Hey there smart people! I have about 3 strange coloured fan leaves on one of my 4 plants and I’m not really sure what to make of it. To me it doesn’t look like any deficiencies that I came across per say. All other leaves look nice and healthy. Kinda randomly scattered. THX!

Leaf fade vs. deficiencyHey everyone, does this look like a deficiency? I’m in week 6 of flower, I had half a week of high temperatures and I’m sure she was affected just a bit and noticed Bud growth slowed slightly. Not sure that influenced this and if it’s a deficiency(magnesium?) or normal leaf fade.

Veins turning light green on lower leavesOne of my plants is getting light green veins on the lower leaves. Is this magnesium deficiency? I can't water currently without risking overwatering, can I just foliar spray BioBizz cal mag to temporarily help recovery? Or is this something else entirely?

Please help identify the cause, interveinal chlorosis since 2 weeks old, no necrosis so far. These two plants are 26 days old. Do they look stunned?Is this magnesium def since it's going from the bottom? Is it possible the first signs started to show when they were just 2 weeks old? Or is this iron? Or is it smth else? Calmag given two days ago. Pistils show already. I water with ph6.2 but no runoff yet to know the soil ph.
