Lightburn, nuteburn or deficencie?

PeppaWutzstarted grow question 3 years ago

I saw some strange brown spots on yellowing leave tips of the upper leave pairs. Is this lightburn or nutrient burn or a deficencie? One plant of 9 is effected. The others look fine. Thanks for your help 😋🖖

P and K toxicity due to excess bloom nutes is likely. You're feeding at an EC of 2.0. Test the runoff of the affected plant, I bet its probably pushing towards 3.0.

Hey Mate, I do think that your girl is suffering light stress. 1xQ6W 2nd Gen. and 2xSF2000 is way too overpowered. I'm going with one Q6W 1st Gen in a 80x150 tent. All of the 3 lights are monsters. Good luck and happy trails for the rest of the way 🤞 Servus, OimRausch

Yellow edges I had just dealt with a calmag deficiency but adding biobizz calmag, but now the leaves are starting to yellow on the edges. Is it still a calcium or magnesium problem, or is it something else?

Leaf Septoria?Can almost see the end in sight on my first grow, and I think I have a problem. Noticed a few lower leaves weeks back with spots, so I removed them and kept cleaning the bottom of the tent, but I think it’s spreading. Is this bad enough to worry about end result?

bottom leaves yellow Helloo So today I've noticed that the bottom leaves are yellow. I don't really think it is a problem since I think the reason is that they don't get enough light because are covered by the bigger leaves on top. But it's better to ask since I'm a newbie. What do you think?
