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.

Leaf problem and purple stems
Hi, I have a problem with my auto. I have purple stems and problems with the leaves. The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem. Is it a nitrogen deficiency ? Thank you for the answer

Leaf tips on all my grows turn upwards slightly. I'm using a 260w HLG Quantum board LED light which is about 2.5ft away from the plant and temps never get higher than 27 degrees with about 60% humidity. Could it be calmag deficiency?

Why are my leaves canoeing?
Noticed that the leaves on one of my plants is started to badly canoe. This plant has been lagging behind the other the whole grow (different strain and provider). Not sure if this is a nutrient deficiency, exceedance, or something else. I flushed both plants.

Dear experts, could you help me ascertain whether the 4th and 5th picture on my Week4 diary is really heat stress? The only reason I think that is because of that slight cupping/curling of the leaf edges. Might there be other problems that could cause this?

Sick plant, nutrient toxicity?
Few leaves on my plant are beginning to burn, plant was always at least 18” away from my viparspectra xs2000 light set at 50% brightness, so I doubt it’s light burn. Temps are always 73-78 inside the grow tent, this strain apple fritter is sensitive to nutes, happy frog too hot?

Weird looking seedlings? (uploaded vid)
My seedlings, especially Seedling 1, look kinda weird to me. Seedling 1 appears to have some weird yellow spots here and there and the leaves look cut? They just look really weird and not like normal cannabis leaves, both seedlings have their leaves going up at the corners.

Hey guys. Leaves not curling upwards as such but I'm getting some leaf tips that seem to be reaching upwards slightly. Does this mean I need to up her cal and mag intake? I read somewhere if the leaf tips are starting to "pray" towards the light it could be a cal/mag def?

Otherwise healthy leaf curling in on itself at top of plant
Anything to be concerned about? This is a plant that has had a history of yellowing leaves due to I think nutrient deficiency. New leaves are coming in light/dark green. Maybe caused by being too close to the lights? (It is my shortest plant with about 1 ft distance)

Struggling with deficiencies (nutrient lockout?)
Hello everyone, I need your help. I've been growing 2 Green Gelato Auto from RQS but I've had some deficiencies for a while now. It's my second grow and it's the first time that I adjust the pH. They are in soil and I'm feeding them with Biobizz liquid nutes at a pH between 6-7.
