Yellowing some leaves

Flaviostarted grow question 6y ago

One of my plants(Quick one RQS) is yellowing some fan leaves. Is she just killing of them because she doesn't need them anymore or Is It some deficiency? The plants look very healthy.

Hi growers I’ve been struggling with an issue, For some reason my plant looks unhealthy could anyone give any thoughts? Thank You I’ve been feeding biobizz which includes all the nutrients I’m still clueless to why my new growth leaves are getting yellow. I flushed it last week and got the runoff back to 6.3 - 6.5 ph but I don’t know how to use the ppm pen any help how do I measure the runoff thanks?

Cal-Mag and N Deficiency in Flower? Thanks!I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

Leaves yellowing These leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?

I have the light at a height of about 40 cm. The photo is taken immediately after watering. The water drains as it should. I use biobiz lite mix. I think it will be poor water quality or spoiled fertilizer. How do you recognize spoiled fertilizer?
