dying top fan leaves
All of my 3 plants are receiving the same treatment but one of them is showing signs of distress. Some of the top fan leaves are getting dry and brittle and dying. I thought perhaps the problem is I haven't been allowing enough run off?

Leaves color changing in flower!!!!
what do you think ? deficiency? or is just normal for leaves to become like this after 7 weeks from seed of an autoflower? max i fed was 400pm just once. I don't think thats overfertilization. Maybe ph lockout? today i fed with 4.5 litres of compost tea + enzymes! pots are 14L.

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?

Looks like fungus problem, should I remove those ill leafs? Remove whole leafs with stem or only leafs? Or maybe it is feed burn?
I have following problem with some bottom leafs. I use nutrients from Biobizz: Grow, Bloom, TopMax, CalMag, ph Down. Water pH is 6.5, feeding amount like in Biobizz chart. Middle and top of plant looks ok. Light schedule 20/4 (4h is dead zone). Is this fungus? Remove those leafs?

Small red dots appeared after feeding. Slowly sprend across a few of mainly the fan leaves and has discoloured to a much paler/ yellow colour. Will a mini flush help this problem?

Tried everything - Red spots almost everywhere. Turn from red to orange/yellow. Fungus?
Getting very frustrated with these speckles. Iv tried decreasing Cal Mend and B-52. Improving air flow. Cleaning the tent head to toe and the res. Iv tried using UC roots. Im really not sure what's going on and IDK what to try to fix it. Grow was going so well. This sucks.

Does color change primarily happen as a result of cooler temperatures at night and lack of nutrients in the medium???

Pale green leaves with reddish tips?
Stress at the top of the canopy. Is this heat stress, light burn, or a combo? Something else? Temp in the tent hit 92.5 F at one point, but it's been high 80's in the tent and the leaf surface temp's have been low 80's. Light was 14 inches at one point but now 24 inches

5th week of flowering Easy Bud, unsure of when and what to do next.
end of the 5th week of flowering, the buds are growing but are still very slime but a few of the pistils have turned red. Have some burn on the top leaves, are these going to cause more issues? Are they likely to bulk up anymore? am I looking at another 2 weeks or is it longer?
