Looks like it has a little heat stress, but still very healthy looking for being in high heat all week.

Yes light heat stress but nothing to worry about. Mother nature has always taken care of herself outside.

Leaf discoloration and curling
I’m not sure what’s wrong but all my other plants are fine. It’s in pearlite and peat moss and I’ve been watering with ph balanced water. I did use a very little bit of half strength dyna grow but I only did a little squirt.

Leaves are looking a bit strange.
Leaves looking sick hope its not root rot, i changed the light but only from 25% q5 to 50% evo 3 maybe it was a bit too close. I tried closer to prevent them from growing more in hight.

Kolas folding upwards?
Some of the tops of some colas are stretching up and not flat to allow the pistils to form correctly. almost looks as though they are stressed - I have had similar things happen with other tents and had to remove the plants in the end. How can I stop this?

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?

The leaves have become glossy and yellow
The last couple of days, the leaves have lifted a bit again and bent the edges, and the leaves are glossy, was it a mistake to keep the light on 24h the first week, or what do the last couple of pics look like? (I have now set the mode to 18/6) so as not to fry the plant

Nutrient problem??? Excess or deficiency?
What do you think is the leaf issue? Open to second opinions. Most everything stayed the same, except: > increased water: 2L to 3L per 7 gal of soil > introduced a bloom booster > increased volume of worm castings, molasses, mycrobes and ethylene to the tea

Leave issue
What is this? Nutrient burn, deficiency, fungus? I tried to look up the answer but it might be different things on different plants. Please help me diagnosis this. The white powder is DE and the small holes are from flea Beatles. But I’m more concerned about the browning.

Cupping
On the right plant in diary pic it shows slight upward cupping on the edges of a few leaves. There are a couple of others on the other side. But 95% of the leaves are fine. During my first try at LST I broke the main stem by 70%. I think this caused the cupping?
