Nute lockout or deficiency? Flush with Florakleen @ week 10 ok?
jokggastarted grow question 5y ago
I am running 4 gal autopots on 50 Coco/Perlite with Jacks 321@80% strength (800PPM), up from 650PPM previous week. Have been seeing curling and leaves dying although the bottom area is green.
Res/Tray@ 6PH/800PPM. Coco slurry @6PH/800PPM.
Temp 81, RH 55%
Should I flush?

Try dropping you pH to the low end of the recommended range (5.7)
Looks like you’ve got an N lockout or some type of salt build up even though you said it’s not a bottom up yellowing issue.
I would flush.
Good luck

Rusty Leaves3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera.
I also have slight "clawing" on many of the upper leaves.
Mg/Ca lockout because of nitrogen toxicity possible?
Doesn´t seem to be fungi, as there are no spores to rub off.

Discolored Older Fan LeafI’ve noticed a couple of the older fan leaves have changed colors. These are also fan leaves that unfortunately get pushed up against the spacebucket walls. So I’m curious if this is normal from them being pressed up to the walls or is it a deficiency? Should they be removed?

Gelbe Verfärbungen der BlätterIch habe komische gelbliche Verfärbungen (quasi Camouflage) an den Blättern einer meiner Pflanzen entdeckt.
Es ist aktuell leider sehr heiß im Zelt mit bis zu 30°C, ansonsten habe ich wie schon den gesamten Grow nach BioBizz Düngeschema gegossen.
Aktuell:
Temp. 28.9°C
RH 35%-42%

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

Calcium deficiency?I'm not so sure if it's calcium deficiency, what do you think?
Watering 100ml of water minimum.
Using 1ml calmag/per 1L(and other nutrients like N,P,K)..soil comes nutrient free.
Should I water her more and add more calmag or is this a different deficiency?

Burnt edges / yellowingWhat are all these burnt edges from? One of the burnt leaves is from the perimeter, so I'm not sure how it could be receiving enough light to burn. I also have a small amount of yellowing towards the bottom. That's normal during flowering if the low-light leaves die, right? Thx4y ago

Sudden Leaf Yellowing – Lighting Issue or Something Else?Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

Dry brittle leavesDiscoloured older leaves curling up at the edges and turning dry and brittle. I think my problem is over or under watering. I've been very careful to avoid overwatering so I'm leaning towards the latter but what I've read online suggests dry/brittle means overwatering. Thoughts?
