Yellow parts of leaves.

started grow question 5y ago
Anyone can suggest what kind of problem is on the photo - brighter inner parts of leaves. My idea would be that it needs more Magnesium?

Yep I would say either CalMag deficiency or the light distance is actually too short. The first proposition seems to be the senser one

Is this light burn?
All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advance

Day 38 autos: is this nitrogen deficiency or something cal mag could help with?
Kia ora whanau, Each of my three flowering autos (the Herbies Beginner Auto Mix #1: Ape Fruit Auto, Purple Chill Auto and Godzilla Cookies Auto) has an issue with yellowing older leaves. Do I need more nitrogen or is this potentially something cal mag would address? TYVMIA!

Hello growers! I'm experiencing some small yellow spots on couple of leaves nothing major. I'm wondering if there's something wrong with my watering, basically I'm giving the plants nutrients every time I'm watering them. Am I wrong?

Leaves with yellow spots
We have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).

Having a problem with bottom leaves turning yellow and dying. Starts off with brown on edges and tip, then leaf yellows and dries up. Potassium deficiency? PH problem? I flushed plants yesterday with 6.5 ph water and sledgehammer flush from fox farm. Pictures on week 10. Thanks!

Yellowing sugar leaves?
Does this yellowing on the sugar leaves look problematic? I know the end is near so I don’t want to do any damage this close to harvest. Think another week will be long enough? Vermiculite/Perlite/Soil @ 40-40-10% Lotus Bloom @ 1/2 dose (700ppm) 100w LED 14” above canopy

Nutrient lockout? [first grow]
My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before. Is it nutrient lockout? Or just deficient? Appreciate every feedback!
