2 weeks in first grow. A few problems. Please help

Hi guys. This is my first grow and having a couple of problems. This is my set up

5inch extractor
carbon filter
600watt hps

temps range from 70 - 90 (a little high?)
humidity range from 30 - 40
ph levels rang from 6.0 - 6.5

Bio bizz all mix soil
bio bizz grow
bio bizz bloom
bio bizz top max

Plants are 3 different auto strains. One ak47, one blueberry and one White Russian.

They have been growing for just over 2 weeks now and I have just started them on 1ml of grow every other day. But around 2/3 days ago one if them started to look a little unwell. Pic below. I'm not sure what's wrong? Maybe lack of nitrogen?

here is one of the other babys. I noticed these two White spots on the leaf the other day. That haven't grown or anything but is this something to worry about?



and this is another pic. I'm not sure if it's just the light but do the leaves look a little yellow? It doesn't look that bad to the naked eye so I'm not sure.



any help will be welcomed.

From looking at the photo, it looks like there is water droplets on your leaves. Be very careful when you water your plants, especially with nutes, so that you don't get it on your plants. It can burn them, and that may be the case with your plants.

With that said, I've grown a lot of autos, and I really don't see any big problem with your plants.

Yeah the plain water feeds I have been spraying as well as pouring directly into the pot. Now I know that's not good I'll make sure it's kept to a minimum.

So was I right to start the grow feed when I did? At what stage shall I start the bloom?

Glad to know my babys are doing well. As I said this is my first grow and just wasnt sure what to expect. I was just worrid that the leaves were sagging a little.

Thanks for ur help m8.

ninety degrees is hotter than the plant likes. keep it in the high seventies if you can.
