Help! Spots on leaves everywhere

[xxsoadxx]

I have a kind of green house indoor with lights and all the plants start showing some deficiency sign or something please help. Is winter and it's coold.

it looks like you have mites and maybe another pest as well. get a loupe all over the backside of those leaves with the tiny spots.

the larger marks are something else. haven't decided if its a nute or other issue. they look a bit like thrip damage, or possibly splash that cooked under the lights.

@bluter beat me to it. Though the larger brown spots don't really look like bug dmage, the smaller pinpoint spots could be mites/thrips. I'd check the undersides of the affected leaves with a loop or microscope. For the larger areas, we need more info on soil type, PH, lighting, watering, nutes, etc.

You still have time! You need to bust out the bug sprays. Them tiny white dots are spider mites, the more they populate the more white spots your gonna see. They group up and they'll cause more damage. Sierra Natural Science has mite killer solutions. Neem oil. Get ahead of it for sure. Spider mites have the ability to survive cold temps as low as -24°

I'm using Alga Grow from Plagaron and Bat Guano. I'm watering every 20 or 30 days because of the winter season. Is well water and I think the ph is ok I will check.

The light I have two on each side of 50w and in the top a 200w led panel in veg mode.

I just add bokashi and earthworm humus.

I thought it could be deficiency of calcium or magnesium.

I will look the leaves with a microscope.

Thank all!
