munchiesart
started grow question 4y ago
We are in the middle of week 6. I think there is a deficiency or a toxicity. I couldn't understand why. Could you please check?

If I had to guess a bit of nitrogen excess, perhaps slight calmag deficiency.

Potassium Excess?
I feel like it looks like a Potassium excess, causing a CalMag deficiency. Any thoughts from the communitys? Old leaves are dark green with brown spots. New foliage is in light green (potassium excess) and developing brown spots on the new foliage as well (CalMag deficiency?)

Magnesium - Nutrient problem
Do I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly. The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1. Has anyone the same problem? Thanks!

Does the paleness concern you?
Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

Possible N Toxicity
I believe I have a N toxicity issue on my hands. Leaves are a dark evergreen color, and I'm noticing some leaves are curling left or right. I've experienced the full out clawing action a while back but never like this. Is anyone able to confirm? How do they look overall?Thank U!

Yellow lower leaves on 8-9 week old plants - Deficiency or age of plant?
Lower leaves are starting to yellow on some of the plants. I think I have corrected my cal/mag issues but now these yellow leaves. Going into week 9 of flower. Is this normal because of the age of the mature plant or a deficiency? Or is it still cal/mag deficiency?

Rusty Leaves
3 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.

Whats wrong with her?
I cant tell what's wrong with her. I recently upped my CalMag nutrients cause I originally thought this was a Calcium deficiency (full nutrient breakdown in diary). I dont want to hinder my harvest so any insight?

Zinc deficiency?
My plant's top leaves appear thin and pale. My ideas are iron deficiency or zinc deficiency. I'm using RO water. The plant was recently aggressively trimmed of course. Should i flush with non-RO water to increase the zinc?
