Is this light burn?
Is this light burn? If not what is it? It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb. I plan to add more but don't want the issue to accelerate. Thanks in advance!

Weird burn
Thought I had a calcium deficiency but now I’m not so sure. Could have got a bit too much direct sun out of the tent. Any ideas on this ?

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Yellowing fan leaves
Larger, older fan leaves turning yellow slowly. Rest of plant still doing great. Also, leaves are reaching for the light. Is this due to maturity? Or might something else be going on?

Leaves losing "color"/turning yellow-ish. (autopot without nutes)
I've been using autopot system wihtout nutrients, plants now went to bloom. Could the smallest of the bunch (NorthenLight left down corner) have some defiency? As others are not "complaining", at least yet. Should purchase nutes that work with my autopot, only biobizz left now.

yellow/dark discolouring of leaves late into flower
Noticed this on about 5 leaves, some more affected than others. The plant is towards the end of the flowering, with about 3 weeks left, better to ignore it now or try to do something ? perhaps leaf Septoria, already increased air flow and decreased humidity
