Hello. I am having problems.

[Blueiyz]

Happy birthday!!! I just celebrated 50!

Any Idea what's causing this? Same plant as above.

That's thrips damage man.

I can see the peppery black specks which is thrip poop and that patchy yellowing from where they rasp and suck on the leaves. Spider mites make fine pale dots and usually webbing. Septoria makes bigger brown spots with yellow halos. This ain't either of those.

Check the undersides with a magnifying glass. Thrips look like tiny tan or brown slivers that run when you disturb them. Tap a leaf over white paper and look for fast skinny crawlers and black dots.

Pull off the worst leaves and trash them. Wipe down stems and undersides with a damp cloth to knock down numbers.

Hit them with a knockdown spray focusing on undersides. Repeat every 3 days for 3-4 cycles to break their life cycle. Use spinosad like Captain Jack's if you can get it, or insecticidal soap, or neem. If you're in late flower avoid oily stuff on buds.

They pupate in the soil so hit that too. Blue sticky cards at canopy level and pot level. Get some beneficial nematodes and drench weekly for 2-3 weeks.

If you're in veg or early flower get some predatory mites like Amblyseius cucumeris and minute pirate bugs.

Clean your fans and walls, reduce dust, improve your intake filtration. Keep humidity 50-60% and don't splash water around when watering.

That overall yellowing also looks like maybe nitrogen deficiency or pH drift. After you get the bugs under control check your pH - should be 6.3-6.8 in soil or 5.8-6.0 in coco. Get back on a balanced feed.

Thank you for the reply

Unbalanced/inadequate nutrition or a root zone issue like pH, too wet etc.

There's no thrip damage or poop there.

Im not sure what's going on with this plant? Any help would be much appreciated. Thank Hou

Looks like manganese

Where on the plant was this leaf and did it show up after removing the leaves regarding your original post? Affected top, middle or lower narrows it down a lot.

 

[Blueiyz]

Here she is. I think looking a little better. At this stage I'm just watering efery 3 days. Is there anything else I should feed her or just let er go?

To much food nutrition burn is what it is called

Looking good (: P, K, Mg and C are your best friends for a bit now. Don't overdo it. If you have or can get silicium, even better.

If anything happens to bottom leaves, you're most likely underfeeding. Weird growth at the top is most likely overfeeding. Just keep posting pics if you're unsure.

I take that back on nutrients burn that is mold spots and its hard to get rid of on the plant but make sure you clean grow place like new so it doesn't happen again

I'd like to see a better picture of those spots. Magnification would be helpful, too.

Just guessing without seeing but are they making like webs spider mites if they are but I still say cinnamon dash it around the top not a lot just lightly and it will not hurt your plants even if you do put a lot and it is safe for your good soil bugs and if there nats than cinnamon works on them too lol

First plant. Should I be considered about the leaves with purple color should I remove them? How many weeks away until harvest

You have about a month left. Maybe longer. Leaves are turning color due to change of season. Nights are getting colder and your plants are showing the start of fall color changes.

Purple leaves is a noraml thing in flower for some phenos. The two are the same strain and in the same pot. One is purple one is not.

The cold air is what is turning your plants purple the temp change is that cause now as far as plants even though they are from the same plant or not. Nit all seed are 100%the same even from the same plant some seeds have a bit of different traits that the other seed don't have genetic so there is nothing wrong you are good and your plants look great

Don't remove all the fan leaves but remove a few purple or green the purple is coming from the changing of temperature at night cold is what does it but all the one on the inside and every other one on the out side and that will help fatten up your buds

Some strains are naturally predisposed to purple hues due to high levels of anthocyanins. Girl Crush is one. I've flowered it out in July last year and it did the same when my tent temps were in the upper 70's at lights out.

I don't grow it for the color, though. I grow it because it's a smooth smoke.
