Could be heat stress as leaves are curling up and you may have a nutrient lock out on stop of that. Coco or soil?

Yellowish color at the tips and wrinkles
My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.

High TDS and low ph runoff - Lockout? deficiency?
Struggling with some bad soil (beginners mistake). I water with dechlorinated tap water at around ph 7.4 and 400ppm (not feeding yet). But runoff ph is 6 and around 1000 ppm. Am I dealing with a N-lockout? why such a ph difference and high TDS value?

Leaves curling into bud
As sugar leaves send their nutes to the buds and start to curl/die, do I need to trim them off before the curled part reaches the buds? The fan leaves were an easy choice to trim...sugar leaves I’d have to trim the leaf rather than stem. Is that ok or necessary?

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?

Yellow leaves question.
Good morning growers, I have noticed some yellowing of the bottom flowers on my one of my plants. Everything else looks extremely vibrant and healthy. Does this look like a watering or nutrient issue? Or is it something I should not be too concerned with ? Thank you everyone :)
