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

Light yellowing leaves Some light yellowing on the leaves, more on the smaller nodes towards the middle. Could this be related to my accidental topping, or possibly due to uneven watering? It was very bushy when i tried to water it last, so i am not sure how evenly the soil was saturated.

Yellow leaves at bottom. New growth good. How she looking?Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day. My theory is that the new line was more sensitive to warmer water temps.

Yellowing and lightening of leaves My back-left plant started to slightly yellow on me from the bottom up. Front-left is also lighter than the rest. Is this a feeding issue? Do they need more nitrogen or did I overwater them? Appreciate your answers :)
