First time grower

1st time grower would like sum advise on my Jack Frost plant it's 3weeks into flower does anything look wrong with what I've done so far for first timer

LOOKING OKAY... Looks like the plant is wanting more light due to the leaves dying off which is normal - however it's a bit early in flowering to be loosing leaves...

Glad to here it looks okay I've just received my 600w bulb so goin to change from 400w will it harm it if change it

No it will not harm it. It wants as much light as you can give.

Okay cheers much appreciated

Only thing is you might have to adjust the height of the new light. Since its stronger the heat output will be higher and if it's at the wrong height you will burn your plants.

Okay thank you for the heads up

Are you feeding anything? Looks a little pale overall but your miles ahead of most first grows

Nope haven't give it nutrients it's had one shot of organic food stuff but other than that water lol

Any recommendations on any nutrients I can use or am I to late now

Id give it a good shot of grow nutes for a few weeks than switch over to a bloom. I'm not too educated on bottled nutes bc I don't water only super soil so I really can't recommend any specific brand but I'm sure someone here can point you in right direction

Thank you for the tip I don't suppose uno when I would use formulex nutrient solotion or big bud nuts
