New Grower They don,t look good

[Autonugs]

Thank you, another bit of info I have learnt, they look ok I just hope they go upwards a bit in the next 4-5 weeks.

Is this first grow?

I don't know their height for some perspective, but those lights look a little close.

What is the pH of the water/feed they're being given?

Biobizz Light runs at around pH 6.0, so shouldn't be the cause of the problem ... but what are you then adding to party when watering?

The plants are all about 10 inches high, they were started on the 1st Jan. Biobizz light mix and I am feeding biobizz veg and bloom. The lights (600hps) are about 10 inches from the top of the plants.
I got some biobizz fish mix last week but I then saw that it is for use when vegging but it also says all the way through?
Thanks

get those lights higher.i do led's so unsure on how far they should be but 10 seems too close.and try to get a closer pic of the damage.it will help us determine if its heat or nute burn or some other problem

Should be double this.
18" - 24" is a better rule of thumb.

But what is the pH of the water you use?
And what is the pH once the nutes have been put in?

Do you have a pH meter?

Ok I will raise the lights a bit, I haven't got a ph meter. The original problem has gone ie brown crispy leaves , but they all seem to be a bit short for 8 weeks.?
I will get one out today and take a picture in my living room.
Thanks for all the tips

They'll be short 'cos they're cowering from the lights.
Raise the lights up to 20" and they won't be so scared of it

You NEED to monitor the pH of what you're putting in.
The brown leaves could very well have been simply a reaction to non-optimal pH of the feeding.

Agreed!!!! Also crispy leaves could be too much sir movement like fan directly at the plant and never moves or rotates.

Okey dokey, as you can see I have raised the lights they are now about 18 inches. I thought using biobizz didn't,t need a ph meter? Will get one tomorrow. So to check the PH I need to water and get a run off?

OK now that I have raised the lights is it too late for them to get taller, I am on week 8
