Hi I've been growing this plants indoor for over three month already, at first stage it got spider mites, so i've got rid of them spraying the leaves with Nim oil mixed with water at night time. i've put some nutrients i have a home for tomatoes. but I think I've nut burn them, but im not sure if i can save the plant. any advice of what's going on with my plant? Thanks!!
She will be fine mate Just lay off the nutes.. give her plain water for a while - Then resume feedings but go easy!
thanks I've also read that I can stop the light for 36 hours after flushing 2 times, so the plant can recover faster. do you think is a good idea?
1st off clean out some of the dead and affected fan leaves, 2nd flush with PH water and use only water for a week, depending on what nutes you have cut it back to 1/3 the package dose. Use that dose and slowly increase it to a 50% mix. Looks like you may have burnt the leaf spraying the neem, I would also keep treating for the mites even if you don't see any signs of them up to week 3 in flower, after that point if you still have issues with mites then good luck. I've seen entire grows pulled due to them late in flower. Nasty little shits they are. Just keep a close eye on them and I'm sure they will be fine if taken good care of from this point out, once all done take everything you have exposed to the mites and clean it over and over, may want to bomb the area also, those shittin bastards will show back up if not cleansed properly.
Do these spider mites exist in all parts of the world. Can you get them anywhere? No problems here just wondering if they only live in warmer climates? I live IL. USA. So its winter and cold. Thanks bud Sent from my SM-G965U using Grasscity Forum mobile app
You probably won't get them now because it's frozen death outside. But they're around, even as far north as you or I.
Also, neem oil is roughly as effective as tapwater in killing off spider mites. Get yourself a more effective pesticide.
If I get them I'll deal with them in the future. My grows pretty clean so. Thanks man! Sent from my SM-G965U using Grasscity Forum mobile app
I want it to get a stronger pesticide first, but the plant was in an early stage and I didnt want to burn it (which I end up doing). at the moment i cant see any spider mite, but my plant in really under stress and having them from september till now, I dont want to give up on them.
I use diatomaceous earth as a preventative measure. It's 100% natural, organic, safe for pets and plants, and will kill the hell out of anything made of chitin. It basically eviscerates them on a molecular level. I dilute it in water and spray it from time to time on the leaves of my plants. I even had an outbreak of scale (think tiny caterpillars instead of tiny spiders) in the herbs that I brought into my house at the start of winter and foolishly put on the floor of my grow tent. They never spread to my cannabis crop, and a couple of treatments made them past tense on my parsley plants.
I live about as far north as one can get in the UP of Michigan, I have seen spider mites all over this area. They have been really bad for about a year around here and I have been lucky enough not to get them in my grow at all. Azamax has been the answer for a couple people I know, one is ready to just burn down his house due to them. He has had the same plants going for almost 9 months battling them. Plan is to chop them this weekend but I'm staying g clear of his place, I don't want them invading my grow at all.
When I said "as effective as tap water" it was only half a dig. For real, they die if they're too wet. Simply washing your leaves off from time to time with a spray bottle will probably keep your crop spider mite free.
Could always spray with a hose if you can drag them somewhere to do that, a shower would work also, as long as you can spray the entire plant, make sure to get the bottoms of the leaf and whatnots.
If you've got a big woody-stemmed plant, that should be no problem. Personally, I'd be nervous firing a stream of water at my plant's leaves. Water is heavy. For my part, I support and spray individual leaves with a plain old spray bottle of water. And I don't even do it that often. Mostly to keep them from getting dusty, as it never rains indoors.
Getting rid of the infestation is the easy part. The underlying problem of why your plants are not utilizing water effectively, thereby leaving them vulnerable to pest infestation is the part of the puzzle that requires solving. Over/under watering, ph, chemical imbalance, poor soil and so on. This is what was relayed to me by the botanist that owns the nursery where I shop. Healthy grow environment = healthy plants = no pests.
hello thanks for the responses, it was very helpful. here is a quick update. I've cut most of the bad leaves, but not all at once as most of them were burnt and I would end up with an empty stick; Followed by watering regularly with balanced ph water (not tap). Gradually I added nutrients, not all at once (more diluted) every two weeks. when started to bring new leaves, I've noticed that the ones were behind, were much greener, so I've put the light higher I guess it was too close to the plant. now i have my plant full of green leaves again, but no sign of flowering yet. should I decrease the light timing to induce flowering? at the moment its in 18/6 thanks.
