Nutrient burn?
Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?

Deficiency help
What deficiencies are these? I’ve flushed her, ph’ed her water and I’m giving her a good amount of nutrients - no nitrogen for the past two weeks I think. Is this just an age thing? I don’t need her to look perfect before harvest, but I’m afraid it’s affecting the bud maturity.

Fine-Tuning Nitrogen Understanding (Deficiency or Toxicity) -- Suspected deficiency, so how do I adjust Fox Farm nutes? Increase ALL 3 nutes to 3/4 dose?
Initial inter-vein yellowing, followed by whole leaf yellowing. Minor leaf stem reddening. Older growth. Normal for flower stage (I believe), but too early for normal and rapid discoloration (week 6). This makes me believe it's a nitrogen deficiency, amplified by SLIGHT overwater

Is the slight yellowing ad curling of these leaves ok or indicative of something?
Curling and yellowing of leaves in a few instances, both near the top and bottom of the plant, with no noticeable discoloration on the branches in between. I'm feeding it 1/4 strength Grow Big (2Cups) and 1/4 strength CalMag (1Cup) when I water every 3rd day. Ph runoff 6.8.

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

Brown/rust spots and yellow leaves at the bottom
Plant in late veg (soil) is showing spreading brown/rust spots on upper leaves and rapid yellowing on lower leaves. Frist only at one plant and now at the others too. I suspect a pH-induced Cal-Mag lockout. But I always check pH to be around 6,5. What should I do?

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

My plant has about 3-4 weeks left, I have always had nute burn so I went what I think was way too light w the nutes this time. Is this a nitrogen deficiency along w calmag deficiency? I'm in week 3 of flower, should I give a good dose of nutes next watering? Advice appreciated.
