Hi there,
A cannabis phosphorus deficiency generally appears on leaves from the lower/older parts of the plant. The lower leaves may turn dark green or yellow, and start getting spots or big splotches that look brown.
Sometimes accompanied by a Calcium deficiency, as Phosphorus and Calcium interact with each other in the plant.

Growing in FFOF with some HF but have nutrient issues...have only given CalMag with RO water and this is what I've got.Wedding Cake nute burn or possible P deficient with yellowing slightly down the edge? Also may have N toxicity with curling leaves? Blueberry also has slightly burnt tips, both plants have yellowing in the oldest growth. All in diary pictures. Thoughts? And how do I fix it?

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

Maybe nutrient burn or?My biggest plant has started looking a little sick, have a feeling it may be some type of nitrogen toxicity? Maybe it’s just got some nute burn? I have flushed it out and will leave it be for a few days and hopefully it perks back up

Nutrient burn/deficiencies/feedingHaving difficulties with a few of my plants, I didn’t add any nutrients until they were close to 30 days old. And then only cal-mag at what I thought were low doses.
One of mine has lost almost all leaves. What would you guys recommend moving forward? I have almost all fox farms

Seedling light green, just want her to be happy.Seedling is slightly yellowing. First ever hydro grow, just wondering what I should look out for. The water is ph 5.8 with fish shit, hyshield, calmag, and nutes according to seedling stage. I even added some extra plain ro water so nutes shouldn't be too strong.
