Yellowing leafs.
Hello guys, my plant is now on the final weeks of flowering, buds are getting bigger and the leafs are getting yellow pretty fast. It's this last thing that scares me a little, I know it's completely normal due to flowering but I wanted to ear your thoughts about it. Thank you 😊

Early senescence on Runtz?
Based on your experience growing Runtz and/or the pictures posted below, what week would you say we're in? I'm asking cause leaves are yellowing and unless I overwatered them it looks like a very early senescence, no? I'm a newbie so there are obvious things I don't see :) Cheers

Ciao a tutti.. Le foglie che si stanno ingiallendo, può essere una extra fertilizzazione? O eccesso di azoto?

Nitrogen Deficiency?
Think I might have a Nitrogen Deficiency but just wanted to check and confirm with some of you? Leaves are slightly pale and yellow across the plant. I checked runoff Ph last week and it was 6.1 realised it can lockout some calcium so flushed with 6.7. Thanks

yellow/copper appearance in some leaves after first run off watering
hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?
