First Grow - Yellowish/Brown Leaf Tips on 13 Day Old Plant (pics)

I went with auto mostly cuz I didn't want to fool with the 18/6 and wanted to just let it run 24/0. And the shorter time from seed-> harvest was appealing. If you don't mind I may have some future questions/progress pictures to get your opinion on if I should flush again or change anything up.
Anytime...

Nute burn could be the problem or could have been the lights before you set them back further. The curling up could mean too much distilled water at ph of 7 or the lights were pulled too far back.

I treat my wee ones like I treat my clones. I spray w/ seltzer water for added CO2 and dome them with an apple sauce cup. I would get some superthrive and ph your water down to 6.2-6.5 for your next flush, bring the lights back about an inch or two closer and go 18/6. Spritzing with seltzer and keeping her domed during lights on should get the roots going.

I use the same ph probe by Neewer. When I started out I used litmus paper and then those drops that come with the ph up and down kit. I got pretty good at what color my plants liked, but the probe works quicker. I've used the expensive probes like blue lab, oakton and hanna, but they wear out too.

Good luck and next time get some perlite in there for some calcium and magnesium

I'm almost positive it was nute burn, the lights are CFL's and they were never closer than 3 inches. I am definitely going to get a ph probe, perlite, less hot soil for future grows, thanks for the info! Will get an updated picture up for you tomorrow morning triplec.

Here are the update pictures Triplec. One thing I have noticed is it seems the burn has stopped progressing on existing leaves (still too early to tell on the newest leaves, but maybe you can zoom in and tell) which I hope is a good thing considering it had progressed daily until the flush. I can also get a few more pics/different angles if you need.

It doesn't look too bad at all. I think you'll be fine. Let's see it again in 2-3 days.

Here are some updated pics Triplec! There still seems to be minor burn on some of the new tips, but nothing near what it was a few days ago, most of the burn hasnt progressed very much if at all. I have a couple of questions though, if you zoom in on some of the pictures you can still still some slightly yellow tips (better than brown tips I assume? lol). But my question is would it be possible that I overflushed and am now experiencing any nutrient deficiency? I think its still just minor burn, but its worth asking! Also in some of the pictures you can see a lot of the growth is starting to run together, is this normal or does it indicate any problems? Last question, the edges of the leaves are starting to curl up a little bit. I am thinking this could be because the temps have went up to about 82-84, but im also thinking it could be from the flush where the plant could be overwatered, maybe you can clear it up!

The curling could be due to a copper def, but those are rare. The plants doesn't seem droopy so I doubt there anything to worry about overwatering. The yellowing is most likely cal/mag def. I'd get some calmag and use about .75ml per liter of water. Make sure you PH check your water after adding the calmag. It can raise it up pretty high.

I have a little update and a few questions to add, the burn is progressing down the edges of the affected leaves a bit, and some of the newer leaves are starting to burn at the tip too. The leaves that have been burnt the longest are curling up really bad also. A question I have is why didn't the seedling burn earlier on? And why is it just starting to burn (it's been in the same soil)? Sorry if that's a noob question, just trying to learn all I can!
They perhaps didnt burn earlier on because you had her watered to much at the beginning. Now you're letting her be a little drier than before so it's searching for food. Also once leaves start to show symptoms of nude burn, they never heal. I just cut them off. Also I am not sure the lights are a problem. Chi is perfect for these babies at this stage. This is just my opinion.

Thanks for the info! Sounds like thats exactly why it didnt burn early. I'll be posting updat pics in a day or two. The new growth isnt burned and is filling in well :)

Update pics, at 22 days atm. Veg stage has seemed to kick in full force :). I'm thinking that flush saved my ass, thanks again Triplec! One thing i've noticed after the flush is the drainage is a lot better, the soil seems to actually get dry now (before I could feel water weight when lifting on the pot even a week after watering). Now I can feel that the soil is actually drying out (been a week since flush). I think i'm starting to see a few yellow tips start up on that new growth, it may just be the lighting but i'll let you decide! I think i'm due for a watering soon. If you noticed anything out of line let me know Triplec!

I think it's looking good. It's a little yellow. I think you probably need to get some calmag and start putting that with your water. Did you get a ph meter? That could be the reasoning for the yellowing also. A good range is like 5.5-7.0.

Ordered the ph meter a few days ago, should be in soon. Honestly those pictures are right under the lights and that's why it looks more yellow, when I take it out from under the light it is a real nice green color. I'm going to water her either today or tomorrow so I'll try to pick up some calmag. Also should I do another flush with this watering or just water normal?

I think it looks ok. If the plant can wait for water til you can get the ph meter, I'd wait. Either just water normal with run off. Test oh of both feed and run off. If you can send a pic with the lights. You may not need the calmag of its a nice green.

Another update, circled a few things in the first picture that stuck out to me. Yellow tips on new growth, and the leaves on some of the new growth are going a little sideways, any ideas on whats causing this?

Edit: also the leaves aren't that yellow, the picture is from RIGHT under the light so they appear brighter than they are, still a healthy looking green other than the tips on some of the new growth.

Alright Triplec, I need your help once again! Everything has been going fairly smooth, nothing wrong other than a little bit of yellow tips that hasnt progressed down the leaves yet like it did when it was burnt. The past few days the leaves have been drooping a bit, once again some conflicting information told me it was under or overwatering. Leaves havent been as bad the past few days as they were 3-4 days ago so I assume it was overwatering as it has gotten better as the soil is drying out (I could be 100% wrong here, let me know!)
Now the 3 main issues I have are:
1. the tips on some of the very new growth almost looks like the tips are a reddish color
2. there are some brown spots on a few of the new leaves
3. growth seems to have slowed down a lot

I can provide any information/picture angles I can for ya to help diagnose this issue, so let me know what info you need!

A few pictures to better show the brown spots/slight yellowing of leaves. I've checked all the deficiency charts and it looks like it could be a number of things. Anyone can answer if you have any idea!

The first pic says either a cal or a mag def., the second looks almost like a nitrogen def.

What do you feed the plant, how often you do feed and water, when was the last time you feed, and how old are they into veg?

I actually just fed 1/3 dose of FF trio (grow big, big bloom, tiger bloom) with the watering today. I usually water once every 5-7 days (it takes a while for the soil to dry due to relatively poor drainage). I waited this long to feed (4.5 weeks) because the FFOF/FFHF soil I had them in actually burnt at the beginning of veg stage. I flushed a few times since that burn though, and went ahead and fed today because I was pretty sure I was looking at some sort of deficiency.

edit: missed a question ya had, they are about 2-3 weeks into veg give or take a few days (not sure EXACTLY when veg starts) I think they are starting to transition into flowering also (could be wrong).
