All the same strain, Then I have4 hand watered same solution near enough. As you can see no yellowing, racking my brain, 6 weeks 3 days. I’ve only just started top shooter? Any ideas Sent from my iPhone using Tapatalk
Personally I like them to yellow up when they mature in late flower. It means the plant is using up their stored nitrogen. It also gets rid of the excess nitrogen in the plant resulting in a better product (imo). I lean the plants off of nitrogen on purpose during late flower. You could always add more nitrogen, but at this stage of flowering, it seems counterproductive. Nice plants btw.
I know you are racking your brain as to why but just let em finish and enjoy. My 2 centavos.....the auto pot is too wet for them esp this late in the game. The plants dont like their feet wet all the time. One of the good things you can do with a SIP that is not auto filled is let the rez run dry for a day or two so the media dries out more esp in late flower when they are not drinking as much. You can do that with the autopots but it a little more cumbersome. Again, its just a 2 cent thought.
Sound like the problem it all makes sense actually, I’ll give them a break for a day or two never thought of that your right they are stuck in wet nutrients 24/7. Hand watered ones are fine Sent from my iPhone using Tapatalk
