Looks like Heat and overwatering + calcium deficiency possibly caused by Potassium excess.

well it looks like i'm facing nitrogen deficiency.
the leaves are pale on both plants and also plant 1 has very small tiny leaves and leaves turning yellow.
So i think it's nitrogen? i will put 1 ml more of coco bloom A to correct.
if anyone has another opinion let me know.Week 6

Early nute burn or normal?I apologize if this is a stupid question... I'm brand new
What is your guys opinion on this slight discolouring in the centre of the plant.
I'm not sure if this is a really really early nute burn, or if it's just a lack of ChlorophyllLeaves. Color - Yellow

Brown/yellowy Spots and StripesAlright, last night I did a reservoir change. I added a fraction more nutrients to the water (.25ml per gallon). I also topped the plants. This morning I woke up and there were these brown/yellow spots and stripes on the leaves. Any idea what it’s from?
Thanks!Week 3

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 :)Week 3
