Hey all. thought it was about time I helped out here; I have a bunch of pictorials to publish...anyway. plants look good. A few pointers for you.

AD and KP are steering you in the right direction, but I would like to add:
when judging your light distance...place your hand at top of grow canopy...lower light until it is hot on your hand and you wouldn't leave it there...raise lights 2-3 inches and keep light at that distance from now on. you can get even closer if you have a fan dedicated to the airspace directly between the hood and the canopy.

never add nutes to seedlings...Never! wait until you have at least 4-5 alternating nodes and only use diluted formula's for a week; just to acclimate the plants. Nutrient Manufactureres have already figured out the right dosage values needed...So mix according to direction's. don't overfert...make sure that you water in between nutrients, especially in soil. Don't overwater.
In soil...you don't need to add nutes every single or sometimes at all except when plants show a need.

As far as lack of nutrients causing smallish growth in regards to these seedlings...I don't think so...the seedlings in post #1 were too immature for feeding. Plants look like they are not growing when theya re taking root. For some reason yours took awhile to root...Keep in mind that rooting sprouts is not considered vegging. veg starts when you have 4-5 alternating nodes and sprouts have become seedlings by rooting.

Your pots are perfect...looks like one gallon. I start my seeds right in similar pots when growing in soil. 2 weeks before flower...I transplant into 3 gallon pots...peace
latewood Reviewed by latewood on . Liberiamom's Blue Haze grow Here are the (hopefully!!!) three girls - first at about a week old, and then a little over four weeks. Aren't they sweet? They've had a little superthrive this week, and I ordered some Gro Big fertilizer so next week I will give them some of for the first time. I also ordered bat guano- I couldn't resist! When should I feed them that delicacy? Rating: 5
