new growth rolling in, but no yellowing!!!!

They are: 1 week into flower
under 400 w hps/18 inches away from canopy
trainwreck x big bud
2 feet tall
3 gallon buckets

Why is the new/young growth rolling in on the edges and droopey? the big fan leaves and older foliage does not look fucked up. this is occuring every where on the plant, top to bottom.. the soil ph is at 6.5. temperture 71-75 (possibly low 60's at night)degrees farenheight, im using fox farm tiger bloom, but used fox farm big grow right before flowering , which is 6-4-4(about 2 weeks before). there is no yellowing going on the leaves, the color looks fine. new growth is rolled in on sides giving them the look of being small ratty foliage. I can already tell it is going to severley damage my yield if I cant find a remedy. all the guides on here dont seem to have this problem because they all say yellowing or spotting should be seen!!! the rest of the plant looks great. see for your self!!! oh yea the problem has been going on for about 2 weeks now. I flushed the soil yesterday and plants dont look any different today

suggestions????????????

They look rootbound first offf......so besides needing a transplant to a larger container with fresh quality soil I'd check your ph as well. But I think they just need bigger shoes.

I see you did check soil runoff and ph is good.....good for you. Transfer them into 5 gallon pots with quality soil and I bet your problems go away.

good luck.

I can think of three strong possibilities...
Possible overwatering.
Possibly rootbound.
Possibly just needs to recover from the flush. I've used Fox Farms products for the past few years, and give a good flush monthly to alleviate the salt build-up that Fox Farms is notorious for. Sometimes the additional (prolonged) moisture in the soil stresses the ladies a bit.

Will be a couple of weeks for all the nitrogen in the soil gets used-up from your last application. Once used-up, fan leaves will start to yellow, as the plant scavenges those leaves for it's nitrogen.

oops...I just noticed...you said soil ph is 6.5...? Are you using one of those soil ph probes that are notoriously inaccurate? Can you ph ingoing and run-off ph?

Any other additives, like molasses, micronutes, Sweet...?

the plants were rootbound!!! first off they are in a 3 gal pots that had 1-2 inches of perilite on the bottom and then the soil was filled about 1 inch from the top of the pots, so the soil space was probably only 6 inches deep. the roots were all sitting at the bottom of the pot soaking in water and perilte. so im guessing that was probably the problem.... Ill know in a couple of days. the roots were a liittle yellow. I think i might have gotten a little case of root rot too.

thanks man,
ill keep you posted
