Yellowing

[SmUrFx1028]

I have these 2 auto flowers (cheese,critical mass) they are 1 month old now from sprout. I have just been using this basic plant food (10-15-10) as this is my first grow and very much budget. They have started to yellow a little bit around the edges and I’m not sure why, I recently just switched lights from little 6W led bulbs for house lamps to a 50w blue white red LED.

Ok, the plant food
What dosage? Usually it is build it up from 1/4 of what bottle states.

Start here.. It is too much of something
My quick guess is too much K.

Hmm looking at this is seems like it may be to much zinc would could be very likely. I am not filtering my water at home and it’s possible it’s high in zinc

like angry bird stated you wanna start slowly your supply her with more p then you are n... try and switch to like a 6-3-2 formula and go easy also, what soil mix are u using it may be full of nutes so watch it bc autos are very tempermental and dont need much to run on so adjust accordingly looks like nitrogen deficiency to me

Regardless if it progresses flush the pot.

Usually this is pH problem but this one may actually be an imbalance.

Flushing and going on a known good program will help.
