Looks like a possible deficency crawling in. She's looking light in color also. Try feeding with a higher nutrient dose. 🤘😤

Iron deficiency?
I suspect this is an iton deficiency due to excess phosphorus. Opinion? Im using GHE flors trio and added som Gro to make Gro Micro and Bloom in solution at a 1:1:1 ratio. Also added Cal Mend by Dutch Nutrients. Pic are 6 hours apart of new growth.

Should I do full flush til runoff is 300ppm?
So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it? Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow. Today 3L water, pH:6.2, runoff:0.6l, ppm:1450, Ph6.0

Upper leaves turning yellow - Day 28 of flowering - Cinderella Jack Auto
Only "half" of the plant is doing that. I don't think its a pH problem, the other plants are receiving the same source/quantity of water/nutes. My guess is the buds that are receiving more light are "maturing" quickly and the plant is sucking the leaves close to them. Thoughts?

Underfeeding?
Beginner grower here. Had some issues with underwatering and it's slowly recovering. Now am unsure if yellowing leaves are signs of underfeeding as it's still early in flower or due to the underwatering. Bottom leaves yellowing and dying off too. Using GHF Bio line as recommended

They are on the older leaves and they keep getting that faded yellowing starting from the tips. The pH of the run off is 6.43 and they havent been fed a round of nutrients in a week! I thought it was a cal/mag def but they haven't bounced back after a dose. Help please!

Yellow spots on bottom leaves.
Starting to notice big brown/yellow spots on the bottom leaves only. Plants look healthy at the top but not happy(not praying and look droopy). I water every 3/4 days so it’s not a matter of being locked and Calmag is also used. Can’t figure out what the problem is here.

Yellowing leaves
Hey fam, Just ended 3 weeks of flower for this Banana Purple Punch Auto. A heap of yellow leaves basically appeared over night. I fed on the 13th with flower fert (has some N in it) and again on the 18th. This is the only plant that’s going yellow. What do you think?

When to start using Cal Mag?
Tomorrow my Bruce Banner plants will be 2 weeks old. One plant is showing some yellow on the left side of one leaf. No yellow on any leaf tips and no claws. I believe I may have been under watering. My question is should I/can I start using Cal Mag or should I wait longer?

Yellow leaves
Hello, take a look at the pictures please. Leaves are turning yellow and curl. Is this a N burn, or a deficianty from some mineral? Or is this nutrient lockout? Plant does grow well!
