I am going to offer some un-asked for advice.

Use a potting mix, not something with outside soil for an indoor grow...prevents bugs...if you use outdoor sterilize first at 350 degrees for an hour. Commercial mixes have buffers to keep the ph constant longer.

Use real pots, they let the roots get air.

I cannot see the pics as I do this so I may edit, but I get the impression they are surrounded by metal foil....use white, not foil as you could get burns.

The very first picture is most interesting, almost like something ate only the green part of the leaf structure. Everything looks pretty healthy like RT says, and will have a better chance of staying that way with our suggestions.
WashougalWonder Reviewed by WashougalWonder on . White spots Hey guys its my first post here, I just started my first grow and things are overall going pretty well. Ive done a lot of research but actually getting down and growing is a totally different thing. I was able to spot and notice nute burn in some of my plants, and have been only getting water for awhile now. The plants are still pretty young. In this one particular plant I just noticed this white spot on it. It does not look like the nutrient burn I am familiar with. I am inclined to say Rating: 5
