Tips turning light green

Im thinking maybe mg def. but Im not sure. I added some epsom salt to the water about 2 weeks ago 2 tsp/gal and only did it on one watering.

Looks like over fertilisation.

Too many salts in the medium will slow the passage of K and i believe that is a K deficiency brought about by a too saline medium. Try giving a plain water (correct pH) feed and see if the symptoms ease off. if not then it's probably justa K deficiency from not feeding enough...

I used Happy frog soil and have been feeding with Fox Farm Grow Big 2 tsp/gal everyother feeding. I will try straight water with correct ph and see if it clears up.

if it's every other feeding then you're probably not feeding too much.

ya try flushing first with phd water and if it gets worse think ur on it with mg def

Mg deficiency and over feeding/too much n. that thing is way dark so back off the n for sure. They don't look burned though. Epsom should help. You can also foliar feed Epsom to get it a fast shot while you get your feeding straightened out.
