Cal mag issue
Igrowneilstarted grow question 4y ago
Noticed what looks like a calcium issue , the four plants directly under the big led have shown sign of calcium shortage in the plants , I've put a fan on the pots I need to dry out faster to feed with some cal mag will I not use my (N) since it has some or should I use both ?

Hard to tell with the lighting but a calcium deficiency is an all around lack of food—- you need calcium to drive the other nutes in—- looks like you are lacking on all fronts

I would say the brown edges could be from over water/ water to frequent or could be potassium def. Your plants showing pistils so I would lower the grow and increase the bloom part of your schedule and leave the micro as is.

Recurring Cal Mag issuesI’m already at the maximum recommended cal mag dose of 1ml/litre (with nutes at 1000ppm or E.C. 2.0) and I’m still facing issues.
It went away for a few days, but it’s now back.
Should increase the cal mag dose and cut back on the macro nutes to maintain 1000ppm?

Calcium or Phosphorus Deficiency?One of my 3 Cream & Cheese has upper leaves on 3 stems/colas per the pic. The lower leaves are OK, the other 2 plants are fine. Thought calcium at first as phosphorus is more lower leaves? Maybe just add CalMag?
Thank you so much!!

Leaves fading and dying, started from bottom but spreadingI’m starting to be at a loss with this. Calmag issues earlier in veg, seemed to improve for a while but now bottom leaves started to die - I thought this was just due to beginning of flower but it’s getting worse and spreading even to healthier new growth. PH (should be) fine.

Is it a Cal-mag deficiency? From total newbie point of view.I really need help with these dots on leaves - any ideas, pros, masters, exp. amateurs, anyone?
I had no problems just till today on 2 out of 4 trees. (only low humidity in germination, but they lived through)
Photos taken few hours ago, and now it is like 50% more of it. WTH?😓

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Their appears to be little brow spots/specs scattered on the fan leaves, I feel like I’ve seen it before but completely forgot what it was so if anyone knows if it’s a deficiency of any kind it would be appreciated. I ruled out nute burn because only one out of four has it.Week 2
