It's a pH flux. Need to drop your pH more when watering. Bit of Calcium won't hurt her either.

Hi there! Check your pH and make sure you don't have any lockouts or anything. That yellowing starting from the tips looks like a Potassium (K) Deficiency but those curling leaves and darker green says you might have something else too.

What is happening? Leaves
can someone please help me, what am i doing wrong? My guess is to much nutrients or oversalting - Nut lockout? it could also be, I have been watering them every day with fertilizer mix, without a day of water in between, but I always fertilize less than specified - Plagron

Hello guys! Overall the plant looks light green/yellowish and pretty small, with short internodes and bottom leaves with burnt and curled up tips. I give water every 3/4 days and commonly suggested fertilzers quantities. How can I let her recover and get bigger? Thanks :)

Is this light burn?
Is this light burn? If not what is it? It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb. I plan to add more but don't want the issue to accelerate. Thanks in advance!

Yellowing leaves.
Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅 Same issue still applies for now. I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍 Open to all observations.

Nutrient Lockout or Nitrogen deficiency (i.e need more nutes) or Fungus (see stems)
My leaves are yellow but some are turning green. Do they need more nutrients or lockout? I have not gone above 1EC but have seen both strains handling 1.5EC+ in other diaries. All three plants are drinking the water in trays. Res/Tray@ 6.0PH/653PPM. Coco slurry @6PH/500PPM
