I'd check soil/runoff ph and make sure you are in the right range. Also try not to have water sitting on the leaves as it can act like a magnifying glass, and burn the hell out of your leaves. Happy growing.

What nutrient deficiency is this?
What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Yellowing and brown spots on leaves
Can anyone identify why this is happening? I am growing 2 other plants (one the same strain) with identical treatment and this started happening with one of my Royal Jacks. Everyday new leafs show the same symptoms.

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Hello, I would like to know if you know what's happening to my plants. One of them is losing its color, it's turning yellow. And the other one is having a hard time growing, and its tips are turning brown. The leaves are also curling up. Thank you very much for your response.

I've noticed for a few days that the leaves of the plant are turning yellow or looking like in the photo. I'm not sure if it could be some kind of deficiency or lack of nutrients since I haven't fed it more since the last time, and it's taken on a lighter color.

I don't know why it turned yellow, is this normal? The pH is fine too. I raised the light to prevent burning.

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?
