Mr_fluffystarted grow question 7 years ago
Hello is it nut burn or to little nuts? The biggest plants are the ones affected. The big plants also have less dense buds and more white hairs but looks like they have the potential of more dense buds. The EC rises a from 0.8 too 0.9. They drink a lot of water. Have auto topoff

Its a combination of potassium and boroN deficiency, the LEDs ain't helping either. Its sapping the energy the plant hasn't got the fuel to keep up with. its affecting the biggest as they demand more feed as they are bigger and closer to the light by a few inches? if they are closer led par would increase. This Would stem from a pH issue or simply underfeeding the bigger girls. Check your hydro system, flush with pH and nutrient solution. Increase feed. Also increase light off temp, this can affect uptake of nutrients.

This looks like a potassium dificiency to me. If you are using about .9EC you can dial it up slightly but make sure you are using a nutrient that has potassium. Raise the EC to about 1.4 max. This should help but the leaves already effected are goners. Hope this helps!

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.

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?

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.

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?
