Hello it seems you have calmag deficience. How do you try to correct it. You can use epsom salt which is the best for this. You can mix it in water and mist your plant for a quicker effect. Good luck. Bye

Calcium deficiency?
Saw this little brown/yellow parts today. She is in BioBizz LightMix Soil and gets 0.3ml/L BioBizz CalMag 3x per week. pH is above 6.5 . Today I gave her 1ml/L CalMag. Was this the right choice? Is this a calcium deficiency?

Deficiency issue/problem with leaves
Any idea what problem I’m having with my plant/leaves? I’m guessing some type of deficiency because I’ve only fed once and it was a few weeks ago. (Check photos in most recent week). Any advice/ tips would be awesome, thanks!

Flush or what to do ?
Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?

What do you think is causing the spotting, leaf curling, and stunted growth in plant #1? My money is on light burn and/or PH issue. I have a PH control kit I've been using to treat the water, but do you think just treating the water is enough? Using FoxFarm HF soil, no nutes yet
