Leaves going red in the middle of my Bay 11 ??

Second organic soil grow and this has suddenly stated happening for the first time. Any ideas what's going on ? I don't ph the water because it's in soil and so far have had no issues with the other 5 strains I've grown in exactly the same environment.

Now you have an issue...
ph water to 6.0-7.0 and give her some nutes to flush out salt buildup from Copper deficiency

strain mate

U may want to do a flush with a small amount of 3% hydrogen peroxide mixed with ph balanced water... And of course replacement of nutes after done. ..update us as to results

He was growing organic, correct? The very last thing I would recommend is using peroxide. Will completely destroy your soil. Peroxide will KILL all your beneficial bacteria. PH shouldn't matter if you have a good organic medium. When growing in dirt adjusting your PH will actually cause problems as the acids builds up in your soil. Would need more info to diagnose what is actually going on, ie. Soil, ferts, temps, etc.

Maybe in higher dose... But hey w/e its not worth looking for the link to confirm my statement

Grown in biobizz complete soil. Using biobizz organic ferts. Temps are a bit low (13c-23c). The white widow x afgani is doing fine in there, so my be a temp sensitive strain ? Bay 11 is from Cali so is probably a bit chilly is my loft in uk, at autum.

I think it's a temperature issue. Some strains have issues with feeding when the soil gets below 60 degrees Fahrenheit.

The plants seem to be doing well. Personlly, I wouldn't worry about it. There's no necrosis going. Could be genetics or a deficiency, but doesn't look serious really.

Night time temp swings. I'll bet they drop close to 9.4 C Raise the night time temps by 5 C.

Your soil/feed may be a tic high in K too. Not to worry as that won't hurt! Nor will a 9.4 temp fall at night. The thing is I would not let it get worse then 9.4 or your yield could be less.

I run water only organic grows in the Rev's TLO style. I still pH my ingoing liquids to 6.5 to lower the pH "swing" stress as much as I can.

Soil pH swings normally. You water it goes down and as it dries back out it raises back up. If you put in a liquid with a pH of say 4 or over 7.5. The living soil has to work harder to be correct it's self, then when using a balanced pH liquid going in.

Its genetic, the rest well do the same and start to go purple
