Magnesium deficiency?
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., 🌱👍

Leaf issue
What seems to be the issue with older and new leaf growth here? It looks like cal-mag or potassium deficiency in my opinion, but I’m not really sure.

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 streaks between leaf veins
All three of my plants have light green/yellow streaks in between the veins on the leaves that have been present since about week one (week 3 currently). Could this be a magnesium nutrient deficiency, PH issue, or perhaps just overwatering?

Does that look like an early deficiency?
Hi everyone, what ya thinkin' What kind of deficiency could that be? My bet - potassium. last portion of water was ~6.2 pH I wasn't feeding her nutes for ten days by now. Because previous runoff was ~2000 ppm. I thought would be a good idea to do just water for a while.

Raise PH of soil? Is run off actuate reading of soil PH? One of my plants might be getting sick, I need a fix for this ASAP!
So quick question... how would I go about raising PH of my soil. I just took a reading about 5 mins ago from my runoff and it was like 5.8!?! It’s never been 5.8, and I do have a little issue with 3 of my fan leaves on one plant. No soil PH meter. Just flushed them 5 days ago...

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.

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?

Magnesium deficiency?
Can anybody help with the yellowing between the leaves? Is this a magnesium deficiency? The leaves are still pointing upright but do have slight yellow/brown tips. Have recently transplanted into coco with an EC of 0.56. Ph was 5.8 and runoff was 5.7 when last fed. Any ideas?

Yellow and skinny growth?
Can anyone tell me whats going wrong here? I'm guessing the tips yellowing is nutrient burn from the MG soil. But the allover yellowing between the veins and skinny growth has me stumped. My first grow did something similar going into flower. I appreciate any tips or suggestions.
