Everything at this point is ok. Plants are just starting to finish up and the leaves start failing. No worries at this point. Cheers

Cal/mag problem or heat issue?
A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?

The very tips of some leaves are yellow. Should I be worried? Am I over feeding? I'm sure I have been pushing the limits

General concerns about the plant health and expectations from her.
Will nute burn have a big affect on my final yield? Are my buds likely to increase much in size? Leaves discolouring normal at this stage? Does she look likely to produce just popcorn bud at this point? Can I do anything about it? Also not many leaves on the plant?

Bright tips on new growth
Any ideas on the bright/yellowish tips? Nute-burn is unlikely since I did just feed pure water to that point. Maybe light burn? Moved the lights around 5 cm higher. My tap water is around 7.2 pH

Yellow tips upper/newer growth
I'm experiencing some yellowing of the tips in the upper/newer growth. Light stress? Nutrient burn? Deficiency? Ph related issue? Should I do a flush with plain PHed water and check the ph of the runoff? I will do some more pictures tonight with the grow light off.

Black marks on leaves of a slow grower.
Noticed there's black markings on the edges of the leaves on our slowest growing plant. My initial thought was water droplets sitting on it before it had fully broken out or could it be something else?

Black spots on leaves
Black spots present on some fan leaves. During ~3rd month right now. Watering with HESI in Coco Coir, PH ~6 every time, 1/2 runoff water. For about 2 weeks prior to this, I also added very small amount of kelp powder. Soil seems fine.
