Cannapprenticestarted grow question 7y ago
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?

@Cannapprentice I beleive the ph could come down a bit as your plants are lacking potassium and phosphorus
I would also look at incorporating a pk booster into your feeding regime. Some strains are fine and will thrive on whatever you feed them and then there are
some that require more of a boost during flowering. If you bring the ph down to 6.3/6.4 It'll be able to uptake those elements easier.

P-K deficiency. Stop the FloraBlend and increase FloraBloom to 2.5ml/l or 25ml/10l

Any help identifying this leaf issue?Hi everyone, I have a couple of issues popping up on Medea's leaves, and I'm not sure what they are. She's in week three now, and otherwise looks healthy (if growing a little slower than usual). Her last feed (3 days ago) was her first one with a 1/2 dose of the GH trio (0.3ml/L)

Can someone look at my newest pics? 1 of 4 plants (shortest of the 4, so its not light burn) has about 6-8 fan leaves like pics. Happened 36hrs after i did a big flush, that brought my ph down around 6.7. I think its either too much nutes, or lacking phosphorus. Help!Week 8

Dark dots in leaves. Lamp burns?I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

I don’t know for certain what it is. I think it might be a calcium deficiency. I was going to go out and get some gypsum, but I want

I have 2 issues.
1) Some plants are showing white spots on the leaves (pictures 7*/9*/11*).
2) Some have a dented leave (pictures 8*/10*)
Two plants are also growing very slanted (pictures 4*/5*) and i'm not sure if this could cause a problem.
