Neem oil hasn't been terribly effective for me and if you're in flower, you don't want to be spraying OIL on your buds!... what IS effective - against thrips, spider mites, aphids, whiteflies - is Dr. Zymes Eliminator (wish I owned stock in that company!)... it's organic, NOT oil based, can be used up until harvest... Grab some and quickly because the problem is bound to get MUCH worse....
Good luck!

High bro,
This is done by thrips. You can use neem oil to spray the leaves (top and bottom) to kill those f*ckers!

If those are older leaves, my guess is magnesium deficiency. It usually gives old leaves light green or greenish-yellow dots on them. That's really all I can think of, based on the two photos you shared.
I hope this helped.

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!

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

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.

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?

Spot on leaf and white tipsShould I be worried about this spot? It is just one leaf, appeared today, and i've noticed some tips got white/yellow. The latter appeared before any feeding was done. I've only watered with tap water and Power Roots. Nothing else was added until today. Plant looks great otherwis

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.
