questions how can i fix this and the other question is how much water per gallons should i be giving the plants in a 10 gallon and 5 gallon.

btw forgot to mention only using 1tsp per gallon of dyno grow foliage pro every watering they are still in vegetive stage.

are you foliage feeding ? if so it should be done no more than 2x's a week if that. also when foliage feeding one must spray the under-sides of the leaves, because, that is were nutrient up-take takes place in the "stoma's" (located on the undersides of leaves. oif you spray nutrient on top of the leaves this will cause spotting, ect

no im using 1 gallon jugs to water i use dyno grow foliage pro nutrients only using 1tsp per gallon of water and using 2 gallons for the 10 gallon pot and 1 gallon for the 5 gallon.

Greetings and best wishes on this first grow! Black gold has been known to be out of balance at times, depending on the batch from which your particluar bnnags of soil came from. This means that if there is too much of one or more nutrients or not enough of one or more nutrients, certain elements maybe become locked out of the medium. I would suggest top dressing your containers with some high quality worm castings or compost and cease feeding for 10 or so days, giving them only water. This should let them achieve some balance again.

Next up it looks like you may have some damage from Two-spot spider mites. Those tiny white dots on your leaves are most likely the damage from the mites feeding. Look very closely on the underside of a few of the leafs thaat show those white spots and see if you see anything moving.

With cannabis, less is always more. Simply misting the spider mite effect areas with water several days in aa row can make a serious dent in their population.

Good luck!

How did you chek? I know I can spot a spider mite with my naked eye, even their egs, but not everyone has eagle eyes like me. And the damage on the leaves definitely indicates spider mite damage.

I have to agree with Toaster79, unless you have taken steps to irradicated them previously, they are there. I was jsut trying to be extr nice before...
