Brown tips, curling leaves
NobodysBudsanswered grow question 4 years ago
Nut burn, dial back for a second.. if you have an EC mater than can help, but don't expect the reading to be accurate in any way. (similar to why lux doesn't tell you anything about PAR on its own.. it's a poor measuring stick for measuring amount of dissolved solutes, even so, if it is extremely high or low it is a good indicator.)
get pH in order, get TDS in line.. should improve quickly.. .don't let it progress... I have the same thing with some vege crop - ggxww you can see it in my diary. I overfed.. need to give pH-only for a bit.

Looks like light burn / heat stress try backing up your lights some. The curl makes me think so! Happy Growing! 👊

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves.
Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved.
I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.
2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher?
Other suggestions maybe?

Leaf Troubles: Nutrient Overload or Calcium/Magnesium Deficiency?What’s happening with these leaves? The tips are curling up, and the DLI is below 45. I’m unsure if I’m overfeeding nutrients or if there’s a calcium and magnesium deficiency. What do you think the issue is?
Please help me, I need to feed in a few hours.
