Help plz, pests or virus? Or light stress

Using 300 w led on clones. 2 weeks old, about 18 inches from viparspectra. Moved them up to 12 inches recently then dropped back down to 18. They are recently transplanted out of solo cups into ff happy frog. I have given them light nutes but also watering with ro bottled water. ph seems high in soil above 7. Last watering I gave them half gallon of distilled with ph of 6.6, fox farm nutes added. They were clones given to me from friend, I hope its not mites I have seen small black dots under leaves, have sprayed with bon neem twice within the past week. Have some garden safe diamtaceous earth, just not sure how to apply it. Plz help this is my first grow. Using fox farm nutrients, grow big, big bloom, also foliar feeding bush doctor kelp me kelp you. 2nd week into veg, soil grow,room temp 72, humidity has been low 30s but now its at 50

If you made the clones yourself, then treat them as infants. They're still developing a root system to support their needs. You don't need to add nutes while they continue to establish themselves. FF has plenty to last for quite a while for that size plant. Left alone, they are perfectly capable of doing this on their own. Well, keeping the leaves moist is something you need to care about. If that's a self watering container, pay attention to how much you water it. It's still not taking up a lot of water on it's own yet.

Thank you for the reply, they seem to be doing a bit better. I am handwatering and am having trouble with knowing when to water, I have a soil meter it tells me when its getting close to dry. I use the inch dry to my knuckle method. They seem to be growing a bit slow. What about cal magic, I have been watering with reverse osmosis water and I have a bottle on the way.

That sounds right, started off in solo cups, I cut 4 holes in bottom but dranaige still wasn't that great, do you think they could recover?

ya may.. if you go by weight for watering let get real light to pick up before watering, your ph is off also

Alright thank you, ill use that method. Also soil of gauge says it's above seven in soil, I'm not sure how to lower it, water it at 6? I have ph up and down plus strips and tube. Tap water is hard here ,above seven so I don't really use it. What would be best store water? Spring, distilled or ro?

you don't want to use distilled water...
