hey guys here are my 2 week old babies.. something is wrong with them and i dont know why...

have a look at my grow journal to have an idea of what i m talking about :

https://www.rollitup.org/newbie-central/312290-first-time-bubbleponic-led-cfl.html

temps: 72-78
humidity 40-65%
réservoir temps 72-76
ph 6.2-6.5


Need feedback fast pleasee!

Wow, that's a new one to me. I'd say it's a lack of trace nutes, rather than your major N-P or K. Also, I'm not a hydro guy, but isn't that PH a little high? I was thinking it was supposed to be about 5.5 for hydro?

Ya man, all my water for hydro is at the most 6.2, but ideal for me is 5.5 to 5.8. Getting a digital ph meter did wonders for my plants. I was using the test strips at first, what I thought was about 6.0 was actually like 3.7!! Do you have a dig ph meter, if not then it looks like it could be your ph in the water. And is that tinfoil? I heard that could burn small plants but im not positive??

Yes, it is tinfoil.

Tinfoil creates hotspots and potentially burns your plants, especially babies. While this may not be the issue with your plant it's best to stick to mylar or white walls.

You need a pH of around 5.5 (5.3 to 5.8 is the low and high ends). This does make a difference, but I am not saying that pH is your problem. I think you have a general nutrient problem. What nutes are you using? Also, since they are so young, don't over fert your plants. Go with 1/4 to 1/2 strength at the most. And definitely get rid of that tinfoil.

Proper nutes and correct pH level is a good place to start...
