Looks like nutrient burn. She’s a little high in nitrogen. Water feed for a few days and convert to a bloom tea for the week.

Leave spotting
Nute burn? Thrips? Some of those leaves where tucked aggressively at one point. I'm leaning towards nute burn. Think I over did it a little.

I’ve got a little greenhouse grow (I think this is a seedsman lemon auto), but haven’t been able to give the plants as much love as I would have liked this year. I’m a bit worried about this one, any advice would be greatly appreciated if anything could be salvaged?! Thanks

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.

Ph issue?
Hello, I'm getting a bit worried. I'm not sure does this yellowing happen because of my high ph? I think my soil have been moistured pretty long and wouldn't want to try lower their ph with water. Have anyone ideas what is the problem and how could I fix it? Thank you in advance!

Noticed these yellow spots this morning. Not sure if this is a nute deficiency, leaf septoria or too much light. My lights were pretty low as my tent isn't very tall. Have been watering at around 6.4 and recently started feeding a full dose of Big Bloom and Tiger Bloom.

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?
