Hey guys! This is my first grow, but I have a lot of experience with other plants. This plant (green crack) was germinated on October 22nd, so it is about in week 3 of veg. She is in soil with added nutrients, under a 150W grow light, with a 19 on 5 off light schedule.
Humidity is around 45%-55%, and temps range from 70-75 degrees during light on and around 69 degrees with light off. I check the pH of the water every time, making sure that it is between 6.0 and 6.5. I have fed twice with Blue Planet Nutrients 3-2-1 blend. As you can see, her fan leaves look very droopy, and those stems have a purple tint to them. the new leaves coming in don't appear healthy to me. For the first couple weeks she looked great, nice and green and getting full, and then I feel like she started just growing up and not out. I did pick off the new leaves from the node once so that she would have more branches. I will attach pictures of her when she looked healthy, and how she is looking now. I thought that maybe it would be a phosphorus deficiency since the stems are purple-ish, but the nutrients I give have P in it. Any help would be great! thanks(:
Hi Polly, welcome to Percys. I think this is down to over feeding, you shouldn't bee feeding so soon when growing in soil, just water for a few weeks.
The 4th pic looks like she isnt getting enough light also. Just give water for a while, no nutrients. and try and give them a bit more light and they will pick up soo I think 
@macky Okay great! That makes sense. I'll do that and hopefully she'll pick up. Thank you(:
Agree with above, I dont feed any nutes in veg apart from rhizotonic, silicon and a bit of calmag every couple of weeks...Mg deficiency can cause purple stems and is a common deficiency using led or it can be genetics in the plant...temps seem ok although most prefer closer to 26°C (78°F) lights on
Update...here she is now!!
@pollys_plants she seems to be happy now and looking healthy
Sativa to change the things I can, Indica to accept the things I can’t.
@pollys_plants nice looking plant... but I think she is getting too much light? @jacks_farm pointed me to this once, edges are curling up and tips are yellowing. Mabye somebody else can confirm this? Nothing really bad in my, so no need to panic... in my opinion 😉
@galandil yes I think I had the light a little too close! I raised it up some more last night(:
