Nutrient problem
Cheeba_Inuanswered grow question 2 years ago
It looks like early stage cal-mag deficiency. I would try increasing it and see if that helps the issue. If that doesn't help over a week, keep in mind that ph issues or other nutrients, and even environmental conditions can affect how a plant uptakes cal-mag. So with no improvement I would confirm ph and other factors to make sure parameters are where they should be. Its a little different for me growing in coco, but at least once my cal-mag issue was actually a ph pen calibration issue. Happy growing! 👍🌱

Looks like calcium is needed.
Now, Calmag is not meant to be used at such low dose!!
To address a deficiency start with 5ml per litre. Don't worry, CalMag is very gentle and won't burn your plant at this trenght.
But 0.3 ml per litre is a waste of time.
Just don't forget it will take a few days, a week, to start to see some results

Organic slow-release amendments...How does an excess occur? I thought that couldn't happen :-/While these gals are super healthy and look great (What do you think?), I'm looking for high-standard criticism/advice. Are these leaves too dark (Slight claw on certain leaves, N excess?)? Also see very minor tip burn. I'm using organic slow-release amendments...?

Can root damage cause this?The little f*cker has a major damage to his taproot since germination phase. I accidently broke the tip of it. But she was very strong. Fought for her life and won the battle. Now she is 12 days old and shows this. Is this caused by the root damage or from other circumstances?

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.

Defoliation during flowering and overall plant healthShould I proceed with defoliating this plant on day 28 of flowering? I am always a bit reluctant to doing this as I think it stresses the plant a bit too much when it is supposed to be producing flowers, but I would like to hear from you guys.

Damaged Leaf - Problem IdentificationI know it's probably nothing to worry about since this is my by far best growing plant right now, but it doesn't really look like a mutation, more like damage or something. This is the only leaf i encountered, just wanted to check if anybody knopws what it is, hopefully no pest.

Was stimmt hier nicht?Ein Freund von mir hat Probleme mit seiner Pflanze. Er führt leider kein Tagebuch. Sieht für mich aus wie PH Lock aber der PH Wert vom Drain lag bei 5,95 ... das sollte doch im Rahmen sein, oder? Gießwasser konnte ich leider nicht testen. Er hat mir nur den Drain mitgebracht.
