I use ladybugs to eat the spider mites and they do a great job. I haven’t really needed to use anything else. However you will end up with roughly 1500 ladybugs running around your tent. They will do no damage to the plant and keep any soft aphids at bay. They are relatively inexpensive and easy to find. You don’t want to really spray anything on your plants while they are in flower but if you can spray been oil on the underside of the leaves without getting it on the buds that will help too. I prefer the ladybug approach though and it is all natural.

Isopropyl (91% Rubbing alcohol) mixed to a 20% Dilution with water, spray the leaves all make sure you get underneath as well. does wonders to kill of pests and can see the difference in a day or two. Ladybugs and Pray mantis are awesome at killing pests and keeping the garden clean.

When i have mites the best results is when i just kill em between my fingers on the leaves. Its the hard way but more effective than spraying anything I managed to save a few grows like that and never had them destroyed my grow.
About house and garden top booster-i use it also and i had it burned a plant last year.
I use it half dose just once at week 4 flowering.
Be careful with that.
About temps-your plants look like heat suffering.
Make sure canopy temp is no more than 26c.
Make sure to dry soil before watering.

Before your first treatment, cut down their numbers! Control the heat. Have lots of air blowing over the plants and top of growing medium. Spray spider mites off the plants if you can. Spider mites like the heat and hate a windy environment. A cool breezy grow space won't get rid of spider mites, but it makes it harder for them to reproduce so your other control methods are more effective. ​If it's possible for you to bring your plants outside or somewhere safe, you might even consider spraying off as many spider mites as you can, to get their numbers down before you start your main treatments.
Azamax is a time-tested way to rid your grow room of spider mites. Spray plants 15 minutes before lights out, making sure to drench the foliage under the leaves as well as the top of your soil. Use a fan to blow on your leaves to help things dry. Treat your room more than once, even if you believe the spider mites are gone. You can also add small amounts of Azamax when watering your plants, as it will not hurt your roots but will kill spider mites in the soil. You will need a mister (also called a "One-Hand Pressure Sprayer") to spray all the leaves evenly.

1100 ppm is far too much for this stage , some of the leaves look like the claw , as for spider mites , they don’t like warm water , neem oil , or nite nite spider mite . Good luck :+1:

Neem oil will scare them away it seems more deterant than killer.
Insecticidal soap will kill on contact and can use up to harvest.
Also a squirt bottle with 1-6 ratio or water and rubbing alcohol or bleach, can kill off as well.
I'm sure there's some organic ways like ladybugs etc, but the other means are easily accessible.
I had bugs and what a pain and a many day job it was to banish them.

Well, I see 4 types of potential solutions : mechanical control, nettle mix, insecticide spray, and leaf protection. Mechanical control = use a vacuum cleaner to get rid of the visible insects/moths/spiders (be gentle and very careful) and simply kill every insect you find by crashing it. Nettle mix = natural way to drive insects away, but this will require an extra couple of days for your soil to dry (However this will ensure you the soil is no more contaminated). Insecticide spray = could be handmade with potassium soap or you can find advanced chemical solutions in your local growshop. Here are the efficient molecules: tebufenpyrad, deltamethrin, abamectin, pyridaben. Spraying chemicals is always tricky: could be the most efficient solution, but remember you will smoke what's coming out of this plant, this is definitely not recommended when blooming has begun, some compounds may take months to completely dissapear. Leaf protection: using an organic spray (like Biobizz LeafCoat), you will apply a protective layer over the leaves. In your case, I would try a nettle mix + a leaf protection spray, and if your squatters are not gone in a week, go for chemical insecticides very lightly. I'll be around, good luck with these babies!

I’d recommend using neem oil to combat the insects. Neem is safe for your plants. Your coco should be moist, not saturated, about 2” down. I take my index finger and stick it all the way in half way between the main stalk and edge of the pot to feel if it’s wet, moist or dry. If dry, I water. If wet/moist, I wait.

Soap spray insecticide is similar to oil spray, except it doesn’t have the vegetable oil. It also kills insects but is particularly useful for whiteflies, mites, and beetles. Soap spray and oil spray can be used at any time, but are best applied near dawn or dusk.

To make a soap-based insecticide mix 1 ½ tsp of mild soap with a quart of water. Spray it directly on our plants.

As for your feeding, that doesn't look like nutrient burn to me as it would start from the tips of the leaves and work its way inwards. I wouldn't advise feeding loads of nutrients so early on unless the plants are showing signs of deficiencies or pre signs. Also if you water that much daily Id expect the leaves to be drooping as its a lot of water really early on. Half a litre of plain pH'd water should do them some good, but only when your medium is completely dry and not otherwise. Looks like the start of a water PH fluctuation problem to me. Just double check, no harm done. Hope this helps and keep on growing! Any questions, I don't mind you messaging. Goodluck :grinning:
