best plant ever shows yellow. to much sun? pics inside!

[mid-east-stone]

hello friends!
i am starting a new bag seed grow which looks very promising.
it was a fair smoke, sprouted fast and in general shows nice life.
any how, it grows on my window were i have qwite visious sun this time of year. it is a bit yelowish on the bottom leaves but i am afraid to add nuttes as it might burn the 3 week old plant.
the ph is about 6.8 and the soil is a grow mix of a store brand. bit hot so i flushed a week ago with lots of water.
may my baby be hungry?
the plant:





and the new growth:


what do you say?
bit foood?
less sun? (it is crazy hot theese few last days...)
thanks!

Looks like it finally used up all the nutes in the soil. Time to do a light feeding and see how she responds. Good luck.

I'm no guru but I say she looks hungry as well. Mine is 5 weeks old and I just straightened out some ph issues. I did a lot of flushing and haven't fed her lately and she's starting to yellow something similair to yours...mine is definately hungry.

ive never seen a cannabis plant suffer too much sun really , id be feeding your youngen if i were u ,, after 2 weeks its safe to begin feeding ..
that store brand potting mix would have next to no nutes id say ....

Agreed, plant needs to be fed has nitrogen problem. Get some feeding underway but when you feed use only 1/4 strength and be careful of high NPK feeding like do not use anything over 20

I would get something that is balanced and do not listen to the back of the box when it comes to feeding because you can burn them and when you do you have to flush the soil out and the leaves end up getting crispy so you don't want to use to much

Use like 1/2 teaspoon per gallon of water.

WHich nutrients do you have access toO?

how hot is it. But most likely hungry.

That looks like a very small pot...and is only half full with soil-- I would transplant it...or at least add some enriched soil--
If it is really hot tho...it might be that-- Prolly a combo of both--

ive grown in smaller pots but this also can heat up the roots more if not properly cooled.

peace

and lower ph a bit and she will get more availlable.....6.4 - 6.5 is better... and yea she's looking realy hungry....
