Learning how to read my plants.

Ok guys... I've researched for over a year before I decided to order some seeds and give it a try. I have to say the learning curve has been a little harsh so far. I lost a couple of seedlings initialy from having my light too close (dried the stem out), lost a couple overwatering, but this batch has looked good so far. I noticed the top leaves of new growth is lime green instead of dark green like the rest of the plant.
The grow media is coco and perilite with just a touch of fertilize. I just made a mix of general hydroponics in a gallon of water a couple of days ago I started watering with.
what do you guys suggest?

Any time mine has new growth coming from the top it’s a noticeably lighter green until it reaches the size it should be. Now unless it stays that light green or starts to turn yellow I wouldn’t worry to much. Just keep an eye on it. Also keep in mind most deficiencies start from the lower foliage up so watch that as well if your concerned. How old are your babies? They look a little young for nutes.

They are about 3 wks old... I have them under a 600 watt led, about 24" above them. I was thinking it might be too early for nutes but with the coco coir media I wasnt sure.

Some would say 3 weeks is a little early, and others say start with 1/4 of the dosage. It’s really personal preference. Mine are 6-7 weeks old. 7inches tall and they are outside babies. I don’t use nutes. And probably won’t for a few more weeks because I don’t want to risk possibly burning.

If your using straight coco and perlite you can definitely start feeding shortly after the first true leaves. Coco is an inert medium so it doesn't have any nutrients in it from the get go like soil.

Can you post a pic of your plants from the side? Hard to tell from that angle but the stems look a little thin and stretchy.

No such thing in coco. I hit mine with 1/20th str nutes as soon as the cotyledons are formed and it starts pushing out it's first true leaves. With my nutes, 1/20th str is about 100ppm or so.

Regardless, your plant looks fine. New growth is always a lighter color until it gets fully formed, then the plant pumps it up with chlorophyll for proper photosynthesis.

Im planning on transpanting mine outside when they get a little bigger in hopes of the deer not eating them. I did use 1/4 of the recomended amount of nutes. Im still pretty nervous about screwing up, I've never had a green thumb.

I don’t know much about coco so I figured I might be wrong. But I agree. My new growth had always been a lighter green.

I will get a side picture tomorrow im headed to work but I do feel like they are thin and stretchy... Stem is probably 4" tall and about 1/16" in diameter.

There are no nutes in coco for the plant to use, so you have to provide them right from the start at a low enough rate that won't burn them. 100ppm's of a nice balanced nute helps speed up the growth process of seedlings immensely.

Cool, I'll be sure to check back in. Probably need to move your light a little closer or increase the air circulation where they are growing. When you transplant you can bury the stem part ways to get a more compact plant.

Yeah, definitely stretching a bit. Think you got a little gun shy when you burned your last batch. If I were you I'd try and get the lights a little closer. Otherwise they look good. Just make sure you bury some of that stem when you repot and you'll be fine. Don't want the wind knocking them over when they move outside!

Thanks... Hopefully that works well and it stables them up.

Well I lowered the light down to about 16"... Baby still seems to be growing well but the upper leaves are becoming lighter green almost yellow. It may still be fine but Id rather get advice than wing it.20180602_153009.jpg

I have been reading up on things and have found pictures similar to mine with a sulfur deficiency. My Ph in the soil is at about 7.0, I mixed more fertilize/ water Phed down to 5.5 to flush with. Should I add some epsom salt?

What are you currently feeding for nutes?
