Not to be unthankful for the offer of help, genuine enquiry here. why do you need environmental conditions to diagnose a presented obvious state of the leaves? Can't the cause of what's wrong be taken from their appearance without needing to know what growing conditions they are in?
These were cuttings someone gave me that had been in a propagator for a while, they weren't so healthy, the roots that come out of the coco pellets they are in had dried quite a bit. I put them in new coco and watered them a bit, not much, a few times, then as they took I watered them more, they definitely have grown and responded, but the leaves all went a bit funky at one point. There is no run off as I haven't water them that much so as to allow the roots to develop, the roots were only contained within the little coco plugs mostly, they have grown out more into the coco now.
I do ph and ec every time. Ec was around 800 when the leaves went like that, ph is always about 6.0 I'm using a dry fertiliser called woma 123 or something, it's just a basic veg feed, I'm going to change to canna a+b tho for flower. I had also swapped out a 250 watt bulb for a 600 watt bulb for like a day, then realized was too much for them, so I think that probably contributed to the leaves drying a bit, but the damage to them, the darker spots and rust type patches, were already there, the heat just made it worse. The plants are OK and are coming along, but if still like to know what made the leaves go funny, the dark patches are what really dried up and any info I saw on those were over watering, but yeah I don't see how I was over watering, the coco was and is very dry on top for a few inches while I let them grow roots into the deeper moist coco underneath the dry stuff.
