Thanks for replying. Bad thing is that they turn brown and get dry. These pics few days old. If i twist the leaves they become dusty...Plants look good.
What you seeing is natural maturation of the leaves and expect to see more
No worries, my friend![]()
No, more and more plants / tops doing this now. I watered today with 1.0 EC and the drain had 0.8.Is it the only one doing it?
Could be Mg or light burn. But I´ve never seen a Mg deficiency looking like that.... Will Add more Epsom and lower the EC.Hi Findus,
I would not consider that to be normal...with all due respect to Jim. My first thought was light burn till I looked at the picture. I would not increase feeding. That's not the answer...though I would suggest bumping up Mg. I see dark tips, burning on the edges and interveinal chlorosis. In fact maybe drop the ec of nutes when you add more Mg so the ec stays the same. Just less food and more calmag or Epsom salts...whatever you use.
Yes that is the problem...But... your problem its locate only in the top leaves?
Humidity and temps kinda perfect. Maybe lightburn. I don´t have the typical burned tips from nutrient burn.The margin curling could be from too low of humidity or possibly heat stress from the light, the brown tips would be from salt buildup/nutrient burn. The other discoloration in the laves from stress or again overfeeding. Some strains like Bubba Kush will get purplish looking leaves in week 6-8.
