This looks like it could be ph lockout . Try flushing your plant and see how she does

Hi! Check on "tobacco mosaic virus". The yellowish stains could be signs of it. Good luck!! :)

Kind of looks like very weird Potassium excess. Could be a form of PH lockout.

Yellow streaks between leaf veins
All three of my plants have light green/yellow streaks in between the veins on the leaves that have been present since about week one (week 3 currently). Could this be a magnesium nutrient deficiency, PH issue, or perhaps just overwatering?

Late Flower Rapidly Yellowed Leaves
The yellowing leaves have definitely progressed quite a bit in this last week. Does this look like a normal natural late flower nitrogen deficiency? I still want to flush the plant, wondering if I should start the flush now because the leaves are already starting to get yellowed.

Leaves looking a bit discoloured and wilting slightly, what could be causing it?
Leaves are drooping a bit and slightly discoloured, especially when comparing it to the other plant. Also, a couple seem to be growing at a much slower rate, is this anything to worry about or will they catch up? TIA

Bright Green new growth? Is Co2 to blame?
New growth is very bright green. Just introduced an in-line UV filter to help combat and bacteria in system. Also just turned on the Co2 system and got it up to 850ppm. Why is new growth so bright green? Could Co2 do this?

Leaves still goes yellow after flush with pure water 6.5pH, then only water with Biobizz Fishmix and last time all nutrients but 50% of recommended.
After last question with those symptoms, I flushed her with pure 6.5pH water, then next time started to adding only Biobizz Fishmix, and another next time I started to add all nutrients again but 50% of recommended. Buds, the white ends of the flowers begin to turn brown as well.

Wilting and turning yellow. Let them dry and flushed with PH water but no change
Hey Guys A few days ago, 3 of my girls started wilting and turning yellow from the top down. Figured I must be over watering them so let them dry out (checked with soil tester) then flushed with PH water but no change They're in 4th week of 60/40 batmix so not fed them yet

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.
Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

Top leaves
Hi Growmies, Two weeks ago i noticed that there are some yellow stripes appeared on the top leaves. The PH fluctuates in DWC can this cause some micro nutrient deficiency but I don’t really know. Do you have any ideas what could be? Thanks
