Absolutely nutrient burn related. I agree with high roller. Water only next few times then dial back on the nutes some.

Is this normal new leaf color growth?
It seems again that my leaves are a touch shiny, slightly curled down, and are a touch yellow. I water only 1 Liter every two days and do not use any fertilizer apart from coffee grounds and aquarium water which has slight minerals. Thanks for the help in advance

Any ideas what this yellow coloration is on the leaves? Only effecting this one flower area (branch) in a lower section of the canopy. I did a complete water change 5 days ago, and completed a feeding as well.

Leave's tips color turning yellow
Hey everyone, for the past 2 days I've noticed that the tips of the leaves are turning yellow. I thought about moving the light away from the girls, even though I'm using an LED (marshydro ts1000). Can you tell me what I'm doing wrong? Should I also adjust the amount of nutrients?

The tips of the leaves on my plants are yellow, not on all of them, especially the ones at the back of the indoor setup. I have a 400w reflector about 50cm away from the plants, and temperatures are around 28C. What could be causing this!

Yellow and fragile leaves 2 week
Couple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn. For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

I noticed some yellowing on some of my leaves. I did some research and think it may have been lead septoria. Not sure. Posting pictures... during defoliation I got rid of them anyway

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

It's been a week since I switched to flowering and new growth on the plant all has a yellow/lime green colour but this seems to go away when the leaves fully grow out and growth in general has not slowed down. Based on the pictures in my diary should I be concerned?

Feeding
How often am I meant to feed and water my plants. I do water my plants every 3 days and after every three feeds I flush. Concerned as all the bottom leaves in my grow are turning yellow but the tops are okay. I do give them Calmag so I’m not sure what the issue is here.
