Necrotic Leaves caused by Calclium defficiencies. ...

Korinthiusstarted grow question 7y ago

Necrotic Leaves caused by Calclium defficiencies. Should they be removed or should they be left on. I removed them from my plant. It appears to have been caused by a PH spike while I was away for 2 days. Plant seems to be recovering, but I removed the leaves yesterday. Thanks.

So..my perspective on when i had leaves that got damaged, I'd evaluate each leaf and if it still had some areas that still appeared healthy i would try and let them ride it out. But if the damage is so severe then were facing the leaf not being able to perform its basic photosynthetic properties, then i would remove. However a leaf thats only partially damaged (spots, etc) the plant can still pull some nutrients and positive plant products from that leaf before it completely dies out. I always see my leaves as photosynthetic real estate and the more available area, the better. (Well up until flowering defoliation time) I hope the leaf damage stops here and doesn't continue to affect others. Keep up the fight! ✌️🍀

Calcium deficiency shows as copper / rust spots on newer leaves, not older ones and even so it shows weeks after the deficiency begins. If by necrotic you mean dark / black / metallic blue spots on leaves, then that's P deficiency, probably due the pH spike you had.

Can anyone tell me what's going on with my plant? Yellowing leaves with brown spots on them. I've never had this issue before so I'm at a loss. I've tried a few things but want an opinion from someone who may help. Thank you.

Hi, After I topped, the new growth tips started growing vigorously, but the leaves are weird. They have a loose&floppy appearance, the serrations on the edges are very wide and one of the leaflet didn't even grow 1/5th of the size of the others.. Do you know what it is? thanks!

I was late watering one night last week and she was looking wilted, then 48 hours later, she looked this like with all fan leaves wilted or dead and crispy and she isn't standing back up after watering. Nute-lockout? Underwatering damage? I always check nute pH. Thoughts?

Hey guys at this stage, I have a doubt. Do I remove the bigger fan leaves, or do I keep them? What Is the difference between the two ways in terms of growth?

Been struggling with leaf issues for weeks. Initially thought lockout due to N toxicity. Plants improved after flush in Week 7 but then promptly started worsening a few days ago. Is this a continuation of a lockout issue? Would you feed? Flush? Advice is welcome! 🙏

Hi everybody! I noticed on the newer leaves those light green spots. Do you know what it is? Never happened to me before. Do I have to worry about some nutrient issue? Cheers.

My Tangie photoperiods small leaves are curling upwards around the edges. Anybody have a reason for this? It's the only one of the 4 exhibiting symptoms like this and only one of my autos of the 8 did the same thing. Is it too much or too little water? Not enough airflow?

I'm not sure what's going on, but the tips of several leaves are twisting over and/or turning white. I don't know if it's a nutrient deficiency, nutrient burn, I don't think it's too much heat, but maybe due to sun burn? I'm not finding much luck about white leave tips online.

DEFOLIATION: when should I do it? I start by removing some yellow leafs and I'm at 2 week from harvest. Should I remove the other biggest leaf, even if they didn't shadow the flower and are healthy and green? Also, what means if the stem is reddish?

Second grow, second leaf issues. A quick google leads me to believe its phosphorous deficiency, that may be being made worse as its getting colder? Is it terminal or will she survive?

So- largest plant (photos above) yellowing lower fan leaves, overall light green colour on the entire plant. Possible Nitrogen deficiency? Otherwise she is healthy, budding up well and looks great. Any thoughts from the GD community? Thx as always!

I'm using a coco mix with advanced nutrients organic. I water 1l everyday with little to know runoff.The new growth is a lighter green and the leaves are thin. Is this some sort of deffinency or toxicity? I recently just flushed and stared giving half nutes.
