Lightburn, nuteburn or deficencie?

PeppaWutzstarted grow question 4 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

Nutrient lockout, ph imbalance or nutrient burn?Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

Super Yellow Leaves in Mid/Late Flower Does this bottom left plant need more nitrogen? The last two waterings we've given it 1.5 ml/liter of Micro. Should we give it more? The other 3 plants of the same strain are much smaller, much darker green, and further ahead in flower. These Blue Dream autos are 51 days old.
