Phosphorus deficiency???
TopDrippinPimpstarted grow question 5y ago
Im having a deficiency....i dont think its cal mag issue. Plants are in mid flower and taking in large amounts of nutrients and water. They are also growing pretty fast. Im leaning towards phosphorus deficiency but thought i would ask the fine people of grow diaries!

You are indeed correct!! this is a Phosphorous (P) deficiency which is normal during the flowering stage *This doesn't mean you can ignore it*. Try increasing the flowering fertilizer (usually contains PK) by around 20-30% and see if it makes any difference, if it does help but not completely then increase it a bit more. If nothing changes then check the pH levels of your irrigation solution if its acidic (low), ideally you'd want 6.0-6.5 when growing in soil.
Other than the deficiency grow looks amazing! keep it up!
Happy growing :)

Leaf discoloration... having a hard time deciphering it.Starting to see some leaf discoloration, possibly some spotting, and most recently noticing the tips of newer leaves looking a little burnt. Any experience growers want to point me in the right direction? Seems like it could be nute burn, or potassium deficiency?😩4y ago

Calcium Deficiency Won’t Go Away DWCSo plant #1 is still having some Calcium deficiency issues. I’m using RO water and giving the recommended dose of CaliMagic which is 1tsp(5ml)/gal. I’m in DWC and using LED full spectrum lighting. Why can’t I stop these spots? Should I give more than recommended dose of CaliMagic

On my NLxBB there appears to be rust spots developing on both sets of the first true leaves, i've only fed nutrients once on Day 10 and that was at quarter strength.
Not sure if this is a sign of overwatering or if I need to start feeding with Cal-Mag more regularly.Week 2

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!
