Are you giving any nutrients yet? Coco coir doesn't contain nutrients so you need to start sooner than if you were growing in soil.

Pin the tail on the deficiency
Some yellowing that developed on Gelato Auto in the last coupla days....my guess is nitrogen deficiency since feeding has been light throughout growth but I'm still new to the game and would love to hear from some more seasoned growers

What is happening? (First Grow)

Is this nitrogen deficiency? Should I change the soil?
Is this nitrogen deficiency? I've been feeding them and using pH Down but nothing changes (pH 7.2). Should I replace the soil? They're in CannaTerra mixed with Promix. I've got some FoxFarm Ocean I could move them to.

Yellow leaves at bottom. New growth good. How she looking?
Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day. My theory is that the new line was more sensitive to warmer water temps.

Leaves doing weird stuff
My leaves on one plant are doing this weird thing where some parts are yellow'ish. It looks like a mutation. She is getting the same nutes as the other 3 plants in the garden and they aren't doing this. I've never seen this before so I'm not sure what I'm looking at?

Yellowing 1st set of leaves
Hello, I'm on Day 11 from seed in Coco/perlite using dry Amendments. My girls are yellowing from centre out and have been stuned a few days now. I'm under the assumption it's over-watering. I've air rated, dropped humidity to 45-50%RH. Am I on the right path?

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks
