does this look like N burn? starting to see some purple

these r in FFOF soil, using jacks classic nutes. tomorrow will be the third week of flowering. i flushed a few days ago, but doesnt seem to be getting much better.

it began with some yellowing on the bottom, then progressed up. some of the yellow leaves have burned tips, but others just stay yellow. ive had a lot of dead ones fallin off recently. in the past few days, ive notice some of the top leaves have purple blotches on them

any ideas?

plz help guys. sorry for the bad pics, camera takes shitty up close shots

looks like you got some salt lock up going on, I would flush the soil (3X the amount of medium) and kick back on the nutes to 1/2 stregnth. How much did you flush?

i just left the hose in the soil for a while, let a bunch of water run out the bottom. didnt measure it though. i guess ill do it again real good when they dry up

maybe i should fill up a milk jug, pour it, then repeat that till i get to the right gallon amount. that sounds like itll work better

Thats exactly how I flush, good thinking bro!

theyre starting to get more purple on the leaves. is that molybdenum u think?

ok so we took them outta the pots and they were rootbound. so we used some cat litter buckets that have been sittin in the backyard for bigger pots. bad idea. after we transplanted we realized theyre all crumbly and the plastic is pretty weak from the sun beating down on them for a long time

it seems to be getting worse, although i guess it could be from the transplant. the leaves r turning more purple ontop. does anyone know what causes this purpling?
