Hey friend, I have had N toxicity in all my first grows and the most potent solution is flush. Flush until the runoff water is crystal clear. Leave her be for 1-2 days and then feed her again. Be careful and cut the dose in halfat the grow nute you use. Hope this helps, goood luck!😊🌸

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.
Started around 6th week

Leaves full of brown spotsMy friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.
