about 2-3 weeks in and theres about 4-6 leaves, not fully developed, but starting to turn white, is this watering issues or nutrients? help!
If you have small whitish spots on the leaves, that might be caused by spider mite damage. That's usually the result of not being too clean when you're touching and caring for your plants. Also, if you've reused soil or other equipment, that can cause spider mites to be a problem. They're not too hard to get rid of, but you will want to act fast since this can get out of control more quickly than you might like. If you're trying for a natural or organic grow, I'd suggest neem oil spray. Just put a little neem oil in a water bottle and spray this on the leaves a few times a day. Or you can use pyrethrum. Just go to a gardening or your hydro store. Now, if the leaves are completely white, that sounds like something more than a nutrient or a watering issues. At this point of your grow, if you're in soil (not sure), the plant should have plenty of nutes still. You shouldn't be adding anything at all. In fact, in the beginning, it's best to add as little nutes as possible since young plants are going to stress too much and not be able to rebound. If you're adding nutes already, then you need to cut back a bit. As for it being a watering issue, well, if your plants are too moist (how's the humidity?), you might also be having troubles with some sort of fungus or mold. Lots of things to consider. Pics would help.
without pictures .....if your plants too close to the light you can bleach the leaves....400 hps or larger...post pictures
