I placed my little seed in RW about 5 days ago, and I noticed the leaf tips on one seedling are starting to curl upward just a bit. I would like to avoid problems. I'm thinking I overwatered just abit the night before, does anyone know if this could be the cause. The PH is around 5.75-6.0 Anyone got tips?

Oh and does anyone know about the purple stem. One day, like day 2-3 the stem was an even off-green color. The next day it was a dark purple, almost brown, and it hasn't gone away.

Any tips?

Don't pay any attention to the seedlings in the back, they are de-formed and will probably be plucked in a week or two.

well you say pointing up that wouldn't be over-water.
What's the temp in there?

I noticed it's working on the 2nd leaf set, have you started to feed yet?

Not feeding yet only distilled water. Temp is around 90 prob. not to sure, that was my next guess tho. to hot, but would that cause curling upward?

yup, too hot? Well actually not too sure cause lights are pretty close so it's hard to get an accurate reading. You think that's the cause?

You should have been feeding all along... that's why you got purple stems and overall weak growth. I would be concerned about low humidity with high temps.

Well a lot of ppl say to stay away from nutes for the first couple of weeks is all. Some ppl say to wait untill the bottom leaves even start to mellow and yellow. So the only confusing part is the misleading info. You know? Anyways I think it might just be too hot, and I have the light on 24/0 I'm gonna switch over to the 18/6 photoperiod. So if you got any tips thnx.

I had the same problem last week. Moved my 600w MH up 4" to reduce heat, and they flattened out. I have been feeding since the first leaves (1/4 strength), and been I've upping the nutes slowly. I'm on an E & F system in Coco. I am currently feeding every three hours at 900ppm, less than three weeks from the start of the germination.

Grow Log is below if you're interested.

That's for people growing in a fortified soil/soilless mix. Rockwool has 0 nutes so you gotta give it to em as soon as you see leaves.

dont feed anything for first weeks youll cause nute lock (if growing in soil), and you should try to put a fan to help out that purple stem get nice and strong..

This is my first grow she's a white widdow clone and about 5 weeks old and still on veg. i thought i had a toxic salt build up due to thin leaves starting to grow . This morning i leached her them left her an came back a few hours later 2 find that shes got spots on her leaves and seemed to have a shine like there was residue on leaves . It wasnt sticky or anything though. The spots are a pale yellow coulor and 1 leaf a section of the end is like it has dried up its not yellow though. Ive been growing in bio bizz all mix and using bio bizz veg. sorry about sketchy post but am noob at this . Any help or advice would be much appreciated.
