I agree with GMSlave , it's both pH and nutrient burn due to the high level of Rhizotonic which is too strong as well as raises the pH very much, so it goes in the soil and causes fluctuations. At this stage , you're better off making a spray with the rhiz 1-2ml/L spray twice to six times a day, this brings the auxin (growth hormone) direct to the plant. reduce feeding as much as possible and make sure you have plenty of run off if you're not in soil. Hope this helps ! 🚀

Cant say it is nutrient burn for sure as ph issues can cause this as well. Check your runoff ph and ec levels, that will tell you if its nute burn or ph imbalance. Cheers

Strange leaf deformation Have these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol.

My leaves on plant getting yellow at week 4. Gave her a flush for a few days with a pH of 6.0 but the run off stayed at 4.8. continued flushing with a high pH of 8.0 then the run off went down to 5.8. I did add peat moss to my Coco/perlite. Could that cause the pH to be low?

Deficiency?Hey everybody, I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors. Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos. Please let me know, thanks!
