Light/heat stress most likely! I had a plant taco before because it was too close to the light. ✌️🏻💚🌿

I had this issue about week 4/5. I figured for me it was heat stress. What’s the humidity and it could also possibly light distance.

Will these leave deformities disappear or am I screwed?
Hi there, I recently started a new grow and the leaves seem a bit odd. Do you think the plant will get a hold of itself or not? I myself have opted to wait a couple more days but if things haven't gotten much better in a few days I might restart.

Brown area on leaves
Bonjours à tous. Voilà certaines feuilles de ma plante deviennent attrape des tâches brunes. J'ai donné du GHE essential (oligo-éléments) and cal magnifique (0,3ml/L) ce matin ainsi que du biographie Bloom. Je pense à une carence en magnésium et vous qu'en pensez-vous?

Top leaves turn dark and curl - What can I do?
I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago. Mid last week I started noticing some burn a the tips, so i dialed nutrients back again. By this weekend the tips of the leaves curled further and turned dark. The rest still looks a bit pale, but buds look good.

Why have the leaves on my plant turned pale and crispy?
4 weeks into veg with auto and all of the leaves (including new growth) have turned very pale and dry, starting at the tips and receding rapidly. I’ve used the same two part nutrient solution in the same quantities as I did with the previous same auto, so Disease maybe?

Brown rust spots on oldest leaves
Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

Calcium "deficiency" at 8ml/RO gal and still no improvements in weeks.. now my other tent has started the same spots.
Cal excess or Mag problem? My Blueberry and Wedding Cake Autos are now spotting in new and old growth. Even at 8ml/gal CALiMAGic for a couple weeks no improvements. feeding nutes with two days of just calmagic RO water in between with runoff about 0.5 gal daily in FFOF soil

Leaves curling upwards
What could this be? I consider too intense lighting, could that be possible. Just transplanted a few days ago into these 1,7l pot's. Since it is the first time i use the The Mars Hydro TS 1000 for flowering i think i might have given the plants too much light.

Slight Curling
What to do about the slight curling happening to 2 of my plants? Is it burn from temp/humidity spikes. I had been having issues so I since got a humidity/monitor controller. My lights were very close too so moved them to the recommended distance per the instructions.
