It looks hungry man, like a N deficiency judging at the yellow and extra crispy leafs at the bottom. Suggest upping your dosages if you arent using 50-100% of the recommended

Or with biobizz feed at 50% strength every feed all the way through, no need to water to much runoff either

Yellow/ brown leaves #2 (pics didn’t post the 1st time)
Hey guys so my plants are starting to turn this yellowish color and I’m not sure what the problem could be. Sorry for the second pic, it’s kinda blurry but that’s the actual color compared to the other leaves. It’s my first grow and I’m kinda lost on a solution . Many thanks

Leaf damage/discolouration
The Skunk has been getting a lot of leaf issues. I have been trying to stay on top of picking them off as they appear in case it's rust or similar and can spread. It almost looks like cal mag deficiency, but I'm feeding cal mag each feed. This is the only one effected out of four

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

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.

Hey, on my biggest plant, the leaves are starting to turn yellow from the outside and getting brown spots. Is that a sign of over-fertilization? All the other plants don't have this. Or is it too little?
