(sorry but they have pics while this sticky in this forum does not...)
from those pics and explanations thats my guess.

pics are day22 of flower, strain is fem blueberry from dutch passion, feeding gh micro/grow/bloom, floralicous plus, florablend, liquid koolbloom, hygrozyme and great white. in 5 gallon DWC bucket with 6 in pot lid with hydroton
*interesting to note that this past weekend i gave her just phed water as a kinda of a reset after the first 3 weeks of flower feeding, i think thats exactly when this first appeared...

i know shes way overgrown... unfortunate bs i had to deal with..
under 600w, 70-83 degrees, 48-66 humidity,

How's your ppm? It does look like a P def, but with all those nutes, it could be nute burn, depending on the concentration. Although, if it happened after adding straight water I wouldn't be so sure, but considering it has progressed like this after I'm assuming you've continued with your regular flower feeding schedule, if it had a P def I would have expected it to clear up rather than worsen.

Also, since it's a Blueberry, some of the signs for a P def might be hard to analyze, because the color changes resulting from it (red stems, purple/blue tints) would be normal for your lady :eyesmoke:

I think I might have already posted this on your main thread, but just in case

yea, could be. but its def curling upward. i just dumped the res, all that i could dump i mean, i cant lift the lid and the big as root ball by myself lol its weight is uneven and i cant get under the root ball without fucking up the roots. SOOO i throw a 250g pump in there and sucked out most of the water, id say maybe 1/2 gallon was left behind. i added 9ml of micro,18ml bloom, 5ml hygrozyme, and a few spinkles of great white (per gallon) with 2 gallons of water. 950ppm, bright yellow with a tad of orange PH (5.5-6.0)
hopefully she will stop this acting out and get back in shape!:hump:

You keeping it completely clean in there? Is there any residue built up along the sides? Just in case it is nutrient burn, I'd keep a close eye on her after this feeding and see how she responds. Do you have more pics, by chance? Where is the damage occurring on her? New growth, old growth, top, bottom?

maybe its a heat issue.. temps reach as high as 86 in the room, fucking ac broke... when i plucked this leaf for the photo just now temp was at 84. its not happin to leafs on the outside of the plant, just interior about 2-3 nodes from the tops, so right in the upper middle is where this is happening.

Ah, certainly looks a great deal like a P def:

84F wouldn't cause damage like that, I accidentally let it get above 90 in my case and my girls didn't bat an eyelash (and although they're indica/sativa/ruderalis, they grow more like indica/ruderalis in regards to temp and prefer it to be colder, these plants'll take a lot of abuse ;)), but it is a bit high, I wouldn't let it persist like that for much longer.
