Phosphorus deficiency???
TopDrippinPimpstarted grow question 4 years 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 :)

Need advice as soon as possible. Please see last few pictures of DoSiDos week 3. Am I looking at mottling here? Soil ph maladjusted? Please help if you've seen this before, and what steps do it take moving forward (or am I paranoid, IDK). Thank you!Week 3

On lower leafs some brown patches started to appear and leafs are turning to a yellow color. Think is either Cal def by how it looks like or it is because of PH fluctuations as last week we changed our PH to 6.2 for 4-5 days and now it is back to 5.9 and under 24h spots appeared?Week 3

Plant #3 (pic above) started as a sprout with discoloration. Now on its 4th node, the plant is still affected. Some other plants seem to have it to a lesser degree. I learned it may be TMV, but they are healthy and growing well other than this slight discoloration. Any thoughts?Week 2

Q1) My Dinamed #2 is looking a little concerning. Been spraying with freshly made neem water. You think its leaf miners or could it be a mag def.?
Q2) I'm seeing yellowing tips on some plants (old full-leaf yellowing from pre-transplant). What could it be? Organic nute burn?Week 5

I am noticing a weird discoloration on one of the plants. It's starting from the edges of the leaves and growing towards the middle. You can see it in the last photo. I have looked on a few guides, but I haven't been able to find this issue. Can you see what's wrong?Week 2

Hi!
I have spots forming between the leaf veins.
Most are a red/rusty color and necrotic but a few are purplish red and still flexible like the healthy part of the leaf.
The only affected leaves are near the top of the plant but not the very top either.
Do anybody have an idea?Week 9
