Hey everyone, I'm pretty new to growing but have a pretty good grasp on what I'm doing....did a few successful outdoors but this is really my first indoor run..I'm vegging 3 bag seed from some really good dank my buddy gave me..found 3 seeds in the whole pound and all 3 sprouted.. so we decided to grow in my closet since I have my own place and what not...theyre.currently vegging under a 250w mh with a 15k bulb..it was a spare fixture for my saltwater tank... anyways one plant is showing some spotting on the leaves and I wanted to ask the vets what they think it could be. Could it be the bulb spectrum? That's kinda what I'm thinking

I should probably add that I'm using mg soil (this could be the problem) but the nearest nursery is like 30 miles away.. and I'm watering with ro water I make myself. .only thing I've fed em is a little bit of fish emulsions

Cant really tell anything from that pic. Could you take 1 in natural light or take a macro?

Alright here's a pic on normal light...it's the best I can get. Idk about it being spider mites...I haven't seen any or any webs.. hmmm maybe I'll go get a ph tester and test the soil...my gut is telling me it's the mg soil

It looks a bit like heat stress, how close is your light, are you foliar spraying ?

They're about 14 inches from the light...they have good air circulation.. I can hold my hand an inch above the plants and it's barely warm

It was the curled leaf edges that made me think heat stress, calcium def can sometimes cause that also, nut those white streaks sure do look like spider mites, there's a sticky in the infirmary for sick plants with a lot of pics, have a look there, hope you get it sorted, goodluck
