I don't see the problem here.. Why do you think you're seeing a deficiency? If there IS a deficiency at this point, it probably has everything to do with your pH level which should be 6.3 to be perfect. If you've just got some yellowing leaves underneath, I wouldn't worry about them at all - probably natural dying off because they're not getting any light. Many growers do what is called lollipopping - trimming off all the lower vegetation when they do a scrog - but again, do this carefully. There was one grower here a while back who pretty much took off every single fan leaf and left their plants looking naked and abused. Lost the grow, I'm afraid! I would go ahead and do the defoliation you plan - but I don't think you really need to then wait to flip... the grow looks strong enough to tolerate both as long as you don't go overboard on the defol. Defoliate some today, wait two days, if the plant is ok, defoliate some more, etc... but go ahead and flip now if you want. Good luck!

Hi there The very bottom leaves are just dying off due to lack of light that low down .. it’s completely normal just take them off, Other send that they’re looking nice and healthy 👍 I would defoliate a little bit more to maximise airflow and help keep humidity down Best of luck 🌱

Another side question: Would it be too much stress to denode and do small defoliation again? I am tempted to get the lower structure clear for easier watering + less energy spend on leaves, branches and budsights that get no light? :) Take into consideration that: Last defoliation was 30/9 (26/9 i did topping, LST and MINOR defoliation work) I want to flip to flower as soon as possible.😅

As seen in the video, its only a 1 or two bottom leaves that is yellow/dying. This is what i found https://www.growweedeasy.com/cannabis-plant-problems/magnesium-deficiency https://www.growweedeasy.com/cannabis-plant-problems/nitrogen-deficiency https://www.growweedeasy.com/cannabis-plant-problems/phosphorus-deficiency I have been feeding Biobizz Bioheaven and Biobizz Fish-mix up till now My flower nutrients is: Biobizz BioGrow+BioBloom+Topmax. If we can agree on the deficiency i might invest in CalMag Supplement (Maybe Biobizz) 👉👉Since i want to flip to flower as soon as possible i want to start progressing nutrient schedule to flower (Go from Fishmix+BioHeaven TO BioHeaven+BioGrow+BioBloom+Topmax) https://www.biobizz.com/wp-content/uploads/2020/01/Nutrient-Schedule-EN-2020.pdf With introducing only HALF dosages of flower nutrients next watering/feed. Thanks to anyone answering, helping me getting my ladies in top shape. I will be answering all questions in comments and replying :)
