Not Sure

is this normal size for an outdoor weed plant about 3 weeks into vegie ...planted begin of may.. it gets about 6 hours of direct sun and the rest time not neccesary shade but no direct sunlight also im using fox farm grow big for food

it looks ok...could be bigger...leave it in the sun as much as you can...dont over water it...and becareful using grow big right now...what soil are you using? most soils out there tell you not to use nutes for 3 months.. good luck

using miracle grow is that ok or should i change soil

i would stay away from that as much as possible...it will be ok for now. you dont want to put stress the plant right now by transplanting. but when it gets a foot tall or so...get it in some roots organic or Fox farms ocean forrest.. I would go with Roots Organic though..

Miracle Grow is fine as long as it doesn't have all the nutrients, MO potting soil is actually pretty good.

I agree with those guys, mostly about being careful with the nutes. Your plant is behind schedule, so just because it's 3 weeks old, doesn't mean that you feed it like a 3 week old. It needs fed like a 7-10 day old, which is zero fert, in that soil you're using. You can worry about feeding it when it's about as tall, and wide, as the pot it's in, which'll tell you that the roots have likely occupied most of the space in the pot, and have the soil nearly depleted. More sunlight is what you need, if you want to speed things up, right now.

The downfall with MG soils, is that they can retain too much water, as-is, outta the bag. Add some perlite, and they work great. They can work good outta the bag too, especially the potting soil(as mentioned), as long as you have your watering habits fine-tuned. The hard part, I've found, is keeping the edges moist, while not leaving the center-mass soaked, especially with small plants in big pots. When the plants get bigger, that becomes a non-issue, because they wick so much water.

i stay in southern cali a lot of overcast and been a cloudy week .. really dont want to inside grow but is there anything i can do for light on cloudy days or should i just b patient

You should be okay, as long as there's no trees or anything shading the plants. Alot more sun comes through the clouds, than you would think. Trust me, I've checked it with my light meter, and it's quite impressive.
