Leaf with weird dots

Got her in calmag my friend, she will bounce right back! Keep happy and relax. Always here to help, drop me a message in the future if you ever need advice with growing.

Hi, and I wish you continued fun with your grow. The symptoms your plant is showing are the first signs of a calcium and/or magnesium deficiency. Unfortunately, in the early stages it’s always a bit difficult to tell them apart. That’s why I always recommend a CalMag complex your fertilizer manufacturer should have one. In your diaries I see that you’re using Canna products. You can increase the dosage. What I can also recommend is Boom Boom Spray from BioTabs. You can spray it as a solution onto the leaves before the end of the light cycle, or alternatively before sunrise. I’ve had really good experiences with Boom Boom Spray. https://biotabs.nl/de/produkt/boom-boom-spray/ Alternatively, you can also use a solution of water + Epsom salts and spray this onto your leaves as well.

Yes, evidence of a calcium deficiency............but there are also signs of general incorrect feeding as well..........but unsure which diary to check out to see where things are going wrong.

Low calcium can do that, but depending on how those symptoms progress could be a couple other things too. if damage stays around the perimiter and some chlorosis accompanies it, low k becomes the likely candidate. if interveinal chlorosis accompanies it and spots/damage not limited to those outside serated portions, could be low Mg if just rust spots, low Ca. reference a 'marijuana leaf symptom chart' and you can see what i mean... even where it originates on plant can help diagnose. Symptoms are rarely discrete. Almost always have to eliminate possibilities through cross-referencing
