Tip of leaves curling upwards?

Soil looks wet other than that your plant looks fine.

 

There's nothing wrong with your seedlings other than your soil mix is too dense and wet. They don't like the roots sitting in wet soil all the time and need defined wet/dry cycles to stay healthy. A mix too heavy on compost will act like a sponge and hold water. Add gobs of perlite into whatever you're using to improve the drainage. The soil should be so light and arid that unless you water very slowly, it just dumps through and into the drain tray. And the biggest "no no" of all is watering too soon. Right now, the plant is building a root system and getting itself settled. Until roots are done, you get little to no growth above soil level and the plant uses pretty much no water. As it grows and matures it's needs increase, but right now it needs light and you to leave it alone and let it do it's thing. Until it uses up the nutrients in the soil it's in...which won't happen (or shouldn't) before it gets too large for the cups and needs transplanted into a larger container, don't put anything in the soil other than water. Nutrients are nothing more than plant food. They are very important to the plant, but not until they actually need them. They only feed your plant anyway. LIGHT is the most important part of the indoor grow (flower lighting specifically). For every plant you attempt to flower you need the most wattage you can put above it in the correct spectrum for flower. These lights don't cover near the space that most think when first starting out, so don't overload the light you do have with plants. You figure out how many you can flower by how much lighting you have. Flowering more than your lights can handle is just robbing from all. To get the most from a plant, the light and plant need to be as close as possible during the flower cycle so pulling one up just to cover more plants is shooting yourself in the foot. You'll get more at harvest from a single plant that is tended properly, given adequate wattage and plenty of space to spread so light can penetrate the canopy of the plant and develop out lower buds...than you get trying to flower 3 in the same spot.

Sorry...didn't mean to write a book. LOL Just stuff I wish somebody had told me back when I started. Didn't have the benefit of the forums for help and had to wander my way through and figure it out. Certainly not rocket science though or I wouldn't be involved. Read up (find good reliable proven info) on the plant and how it grows and what it needs during the different cycles of life. Read up on lighting and try to get a handle on what you need for what you're attempting to do. CFLs work fine for veg. We use them ourselves just because they don't create so much heat. But they just don't do the job during flower. They don't have the power to force the plant to grow. We're attempting to mimic the sun with the indoor setup so you can understand why you have to really overkill on the lighting. But it boils down to the fact that unless you have the right lighting to force them to grow and flower off, you just won't get much of a harvest. You can flower them with CFLs, but you'll be greatly disappointed in the result. Best of luck and remember that the more you know about what you're doing, the better the outcome. Have fun!! TWW

 

leaf margins curling up too hot

a small fan pc type will help

curling down water logged or too wet

locate temp gauge and fan close by will ease temps and use up excess water in soil/plant

good luck
