Nutes: Too Much or Too Little

[DooDahMan]

This is my first grow attempt.
So far it has been going very well...
She is an Afghan Kush Ryder...
The last few days I have noticed that her first set of leaves ( not the very first set of leaves rather the first true leaves ) are starting to yellow a bit.
I have done a ton of research but my eye isn't what it will be and I know it's been asked a thousand times but it this Nute burn or lack of Nitrogen? They look very similar in internet pics...
She is 15-16 days old and I have started her on low-med strength nutes...General Hydro MaxiGrow 10-5-14.
I have attached pics and appreciate an experienced growers eye...
Thank You.

She is N hungry my friend, make sure your pH is correct and feed her more N the leaves may or may not turn back green(probably not) but as long as it doesn't get worse you know you fixed it. The thing with hydro is that you will see problems arise much more quickly but they also are fixed much more rapidly. Hope this helps and if you have any more questions ask away

Here is a chart that really helps explain pH and that is probably the most important thing in hydro period. It shows what nutrients are available at what different pH's note: the one on the left is for hydro

Also to add to derek420colorado, it will help to know what what rate your feeding (ppms) when you say low to med dose that makes me nervous, if you have an TDS/EC meter in case your overdosing which will be very easy to do on them little ones ,locking out the roots. cheers.

@IndicaIVoz yep you are right

Wow...thanks all.
I check the Ph everyday...I use drops so I can't be 100% accurate but I keep it in the yellow...
The ppm was at 1050 ...I just added a 1/2 teaspoon of the 10-5-14 bringing it up to 1267...I use reverse osmosis water so the original ppm was only 9-11 ppm when tested.
I had a chart that said after about two weeks the ppm should be at 900-1000 I was aiming for that area thinking maybe that was a bit too high?
I didn't want to nute too quickly as I've been reading to go lite on autos...
I'll see how she goes!!!

Yeah just as i suspected that's way to high for those girls aim for around 200-250ppm, I can only tell you what i would have in there each grower has there own style method and grower level. Never follow the charts rule of thumb is 1/4 strength

Sweet...my tomatoes are going to love that res tank excess after I fix it....!!!

Haha too right mate but def do some research on using General Hydro MaxiGrow and read up on some blogs for autos if you can find some and just see what works for them using GHM with RO.

@DooDahMan I think you should also do a complete rez change something aint right that is for sure, she is locked out. What that means is that basically there is something wrong and the roots aren't taking up the nutrients that you are feeding her. @IndicaIVoz is correct in the fact that there is no way that little baby should be any where near 1000ppms. More like 250 as stated above
