Itโs actually a form of mold
Defoliate the infected leaves
And get more airflow
And reduce humidity to just under 50
Hope this helps as Iโve had the same problem
Happy growing

pH fluctuations will cause similar issues... check the pH of the water/feed going in and check again coming out.
If everything is good, then it also has some similarities of Nitrogen def.
Hope that helps.
Happy Growing!๐๐๐

Leaves Turning Yellow - RQS Watermelon AutoHi GrowCommunity! I am currently growing a RQS Watermelon Auto. The plant is in week six and started flowering two weeks back. I did some LST which the plant handled quite well. I am seeing leaves turning yellow starting from the inside. Is it missing nitrogen? Thx in advance..

Yellow leaf tipsHello,
I think I have a slight over-fertilisation.
Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?
