Cannabis Nutrient Deficiency: Phosphorus

Cannabis Nutrient Deficiency: Phosphorus

My Stardawg mother plant has come down with the sickness. After some recent cuts were taken for the next round of aeroponic clones, she started to present some yellowing and spotting in the leaves. At first I thought it was cal-mag, turned out to be phosphorus. Take a watch for more information.

    I know everyone loves organic… I had similar situation happening and lost over 60% of my yield in the end. My 20 year grower buddy told me i should have just added Miracle Grow. Well the next year it started in again, I use happy frog, roots organic, bat guano, humic acid, bx mix, perlite in 10 gallon air pots on top of the bed … They did great til they get bigger, I added Miracle Grow and yes, it was a MIRACLE! Saved me 80% ! Thank you MG Bottom line, i live in a swappy area and lots of plant life around, so you will need to add a lot of nitrogen! Happy growing!

    I keep seeing all this nitrogen vs potassium war debate… This plant was most definitely phosphorus and then potassium deficient and I repeat “not nitrogen deficient “!…

    I have the same problem. What did you do you use to get them out are the deficiency? And did they come out of the deficiency still healthy?

    I know this is a old video but thank you for posting this. I’ve been beating my head off the wall for weeks. I took clones from a flowering plant that had carried over the unknown deficiency then it cleared up and then came back!!! Every where I was looking was saying add cal mag 🤦‍♂️
