Phosphorous deficiency?I have been dealing with this for a few weeks Looks like a phosphorus deficiency to me I have been giving 0.2g/L of a PK 52-34 once a week for 2 weeks. Base substrate is silty, high in PPM and little alkaline, poor in absorbable nutrients. Sunny UV 13 most of the time.

Possible Phosphorus Deficiency?Hey everyone, what do you think—do my plants have a phosphorus deficiency? Two buds are turning a bit purple, and the lower leaves are easy to remove even though they are still green. Photos are in my Grow diary.

Giant autoflower I didn't expect this Fastbuds CBD 20:1 autoflower to grow so big. I'm having issues: can't get past 600ppm with Remo nutrients without causing burn, but lower leaves show phosphorus deficiency. The plant is 12 weeks old, and the buds aren't fattening up. Grow 80x80x200cm

Dark Green Leaves and Purple Stems Plant B has had no nutes its entire life in FFHF soil (3 weeks). Stems are a purplish color and starting to droop a little. Water is always pH'd around 6.3 but I haven't tested the runoff yet. Phosphorus deficiency? Heat Stress? Watering conflict? NL Photo just started flowering.

The stems began to turn red Guys, I need your help! The stems began to turn red. Yesterday it was less, but today it is more saturated and spreads to the veins of the leaves. Could it be a phosphorus deficiency, or am I worrying for nothing? And what is better to do in this case?

Purple or red Hi everyone. So I have a plant in early flower end of week 4. I noticed stems have taking on a purplish or red color. It's a Banana Purple Punch so I don't know if it's a genetics thing or a deficiency. Phosphorus?

What could this deficiency be? Are old leaves, could it be nitrogen or phosphorus? The last watering gave it a good nitrogen watering and it is in the second week of flowering finished.

Possible P Deficiency?Hey everyone, hope all is well. I noticed these past few days some dark spots appearing on some of my higher leaves. From what I’ve read it looks like it could be a Phosphorus deficiency. Any ideas? It’s on two out of three plants of the same strain. All same feeding schedule.
