Necrotic Leaves caused by Calclium defficiencies. ...
Korinthiusstarted grow question 6 years 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.

Nutrient deficiency?Hi everyone, I am a first time grower and my plants have been put into flower 10 days ago. I was just curious if the odd coloration of the new growth of leaves is a result of some type of nutrient deficiency or excess, or if it’s just the gene expression of the strain im growing.

Been noticing wet spots on my leaves almost like a slug went thru but it’s not slimy, didn’t leave residue and dissipated fast. My Rh was relatively high that day and right after a feeding in the morning, is this the result of plant “perspiring” or something else? ThanksWeek 8

LSTGood day!
I have a question for experienced growers who've used LST.
The stem usually branches out to 2 branches, one of which is just one big leaf and the other branch has nodes & other branches.
Do you put the branch with the big leaf below the rest, above or prune it?
Thx!

Leaves spotting brown round shapesIdk What to do anymore. I tried flushing the plant that initially had it, and it kept appearing I then fed it again, it kept spreading.
I defoliated all the bad leaves and it started popping up on another plant's leaves.
Why is this happening? How could I end it once and for all?

Help Identifying Ailment! BlackBerry Auto on week 6! Nutrient deficiency? Cant find anything online similar.This is my second grow since switching to hydro. Growth has slowed a lot. Leaves are getting brown spots and almost look like they're being eaten but no pests can be found. No root rot, I dont think I'm over watering them. Since I started hydro it's been a real challenge.
