First plant, leaves going yellow. Help!

Hi

So im growing my first plant ever, a Skunk automatic female to make it a real easy first.

It is doing good and it has started developing trichromes.

But some days ago the lowest leaves started going yellow.
I googled and found out it might be some defficiency so i gave it some Substral fertilizer for indoor plants.

I have also considered that it is perhaps the light that isnt strong enough to reach the lower leaves.

No bettering has yet happened, can any of you guys maybe give me a hint to what is wrong with it or any tips, from the picture attached?

This chart is nice to have. It won't solve all your problems, but may send you in the right direction.

Your new growth looks pretty good though. Also make sure the light is far enough away so you don't get heat damage. It can slow down your growth if you damage the terminal bud (the highest point) or the lateral/axillary buds.

Good luck! Any other problems let me know!

I dont worry about the lights, its an LED so it doesn't go hot.

Pretty awesome graph, saved it.

I will continue to fertilize for a while and see. Thank you for your answer mate

what kind of soil is that?
she's just looks a little hungry, continue feeding schedule...just don't feed to much at one time.

Ok will do.

I dont know what you call a regular bag of dirt to indoor flowers in english, but its pottemuld in danish.

It's just a bag you buy at the supermarket for 2 bucks.

I heard some sand would be good in my soil, but my first attempt in 25% gravel 25% sand and 50% dirt failed. The poor little fella never came out the earth.

So now im just using this

Any soil used for tomatoes tends to be good for MJ. Just add 20-25% perlite to the soil and you cant go wrong.

add a little more light and you may yeild 1 more bong hit

All I know is in the flowering stage ! Plants absorb the nitrogen in the leaves making them yellow ! But this must be in all the leaves and also top ones ! This looks like you been playing with her a little , right?

1 more bong hit, sounds like very little for a bulb change? I dunno, perhaps she do need more light, but do you think it will make a big enough difference? Its a very low voltage bulb, but it shines very bright.

The flowering stage? This is only for non automatics i presume then?

About the playing No i try to contain myself intill harvest, but the paper cone she is currently fitted in has curled one of the leaves that you see on the picture pretty badly.
