I'm about 14 days into my first grow. 4 white widow & 1 purple kush. A few of my seedlings leaf tips are starting to curl down. A few of them also have a weird wave like bend/or curve to the leaves. And one of them has yellow bleach looking spots on the leaf tip and on other parts of the leaf. Idk what I might be doing wrong? Im hoping someone could help me out. -All 5 of the seedlings are in 75% Happy Frog soil and 25% perlite. -Under 3 27w 100-w 6500k CFL lights. -my temp is usually between 68-78 Fahrenheit (highest was at 83F) - humidity fluctuates between 56-68% RH I have only watered when the soil is dry to about 1.5-2 inches deep My water is through a filter attached to a water hose with a ph of 6.0-6.4. I tested my run off water ph for all the plants and it was at a ph 6.4. I planted on 03:13/17. You can try to see everything I mentioned above in the pics I've attached!
