Looks like you may need to add a calmag supplement to your feeding program mate.

Outdoor northern lights auto yellowing early
With 3-4 weeks of flowering still to go, how worried should I be about rapid yellowing? I have kept feeding, i know she is rootbound and I havent checked pH. Do some plants just yellow earlier in flowering or should I act?

Leaves are turning yellow!
One of my plants began turning yellow. The leaves still feel like leaves but just yellow. It's currently in flower and I am using the two part nutrients of Maxigro and Maxibloom with maxibloom currently cause it's in flower. I am pretty sure it is nitrogen deficiency. Help?

Nitrogen toxicity mid-flower
So I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?

I'm on Day 80 now, like 6 to 8 weeks flower. Is this yellowing with spots normal or something I need to fix? What is this?

Magnesium Deficiency ? How can I fix it ?
got a little deficiency (maybe burned? but I think not). I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

Yellow tips
Dont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore? A other reason could be light burn. But with a distance of 50cm I dont think so

Let it grow or cut it out?
One of the seedlings isn't doing so hot. Should I just start a new seedling in it's place or give it more time? I've had a stunted seedling like this before in a previous grow and it ended up yielding a lot...
