tjaymanswered grow question 24d ago Hi brother, i think your plant should be killed. it seems like a case of spider mites.
What I can see:
A lot of fine yellowish stippling (tiny feeding spots) spread across the leaf.
Small red/orange dots along the main vein that look like mites.
A few fine web-like strands.
Leaf edges that are starting to dry out and turn brown.
This pattern is much more typical of spider mites than of whiteflies or aphids.
A quick test:
Take a sheet of white paper.
Hold it underneath the leaf.
Tap the leaf firmly a few times.
If you see tiny reddish or beige dots moving around on the paper after a few seconds, it is almost certainly spider mites.
If this is a cannabis plant (the leaf looks like it might be), I would:
Remove the most heavily infested leaves.
Thoroughly rinse the undersides of all leaves.
Temporarily increase humidity, since spider mites thrive in warm, dry conditions.
Treat the plant every 3–5 days, focusing especially on the undersides of the leaves.
Check nearby plants as well, because spider mites spread very quickly.
Based on the photos, I would estimate:
85–90% chance of spider mites
10–15% chance of a combination of spider mites and a secondary fungal issue or residue
If you can take one more very sharp close-up of the main leaf vein (preferably using digital zoom), I can likely confirm with near certainty whether those red/orange dots are spider mites.
