Some yellow leaves anyone have any ideas

White widow auto the plant in the back is 1 week into flower showing signs of nut burning tips and yellowing leaves here and there. I think she was under watered last week because she had some leaves almost lifeless and wilting towards the bottom of the plant but perked back up after watering. but ever since this this has been happening any ideas. The plant in the front is 4 weeks into flower i dont have any yellowing of the leaves besides some minor fan leaf deficiency towards the top of the plant and she never showed any signs of wilting and being underwatered like this one. they are in 7 gallon fabric pot’s and i give them 1 gallon or so every 3 days until i get some run off . now that they are into flower. I guess the one in the back needs more water more frequently then the other.


Hey @Tom6377 you have a bit of burn and wilting going on. I would defoliate the yellow leaves and possibly some of the pale green leaves with yellowing around the edges. Once they go into flower they can really need more H2O. So your just dealing the consequences of lack of water. Not a good time for that to happen but no worries you responded well.

Hey friend,

All I focused on was the leaf in your plant below the circled area in the last picture. The one with green veins and yellowing.

I am still learning about nutrient deficiencies.

Someone will chime in and give you better advice than I can.

I would probably say its just old leaves dying off there isnt alot of leaves that are doing it i would be more worried if there was alot more leaves going yellow but this is my opinion just wait and see what other members say first
