Phosphorus deficiency?

so I believe one of my plants have a phosphorus deficiency leaves are curling a bit branches have purple on them , and have some splotches on a few leaves.
This plant is still in veg stage. I was wondering if I can use tiger bloom in veg since I have it already and is higher in phosphorus 0-8-4 I believe. Here are a few pics thanks!
Also I just switched the light to finish veg into a hps 1000w hps from a 600watt MH so I'm thinking more light more phosphorus IMG_6425.JPGIMG_6424.JPGIMG_6426.JPG

doesn't look like P def to me

If your ph adjusting with phoshoric acid (ph down) its extremely unlikely you have P def

its hard to tell with the lights messing up the color but im thinking your plants are looking for more N and possibly more nutrients all around

the fan leaves look small,,are you removing the fan leaves?

hmm its a tuff call, still don't think its P def
now that the lights are off the color shows more

the fan leaves would have likely given us more to work with

im not sure why your removing them unless theyre unhealthy?.... it like saying gee wiz I wish my solar powered system had fewer solar panels

do you know what EC/ppm you've been feeding them?

Not sure what the ppm/ex are ,I've been using fox farm grow big for nutrition 3teaspoons every other water per gallon. As for the leaves as I stated I removed some, I will be scroging and wanted some of the middle Shute's to get light, I've already super cropped and plant was doing well, I only removed about 10 leaves and they where removed on different days. Also as I said I transferred the plants from a 4x4x6 to a 5x10x6.5 tent and that's when I started to notice change, I wanted to get them under the scrog net , they went from being under a MH 600watt to now being under a 1000w hps light, they also went from a light schedule of 20/4 to straight 24/0. One last factor is that I did feed them nutrients back to back because I super cropped. My assumption was and still is phosphorus deficiency which brings me back to my original question which was if I could use tiger bloom in veg to boost my Phosphorus? Oh and my ph is at 6.5 never below 6 and never above 7 and that's tap water unless my digital Hanna ph meter is off.

I haven't use pH down here are some better pictures and I have been removing big leaves to let light in

I think it's an all around definiciency, including magnesium and phosphorus.

What soil did you start off in? Pots size? AND how long they've been growing in those pots?

I can probably help from there. I wouldn't use Tiger bloom, I'd use Fox Farms base nutrients if your soil is depleated OR if you're in soil-less mix which would have NO nutrients and required you immediately feed a full spectrum nutrient line.

I used pro mix organic soil
Started off in solo cups
Been in pots for 3.5 weeks
You say don't use tiger bloom but then you say to use fox farm nutrients.....Tiger bloom is a fox farm nutrient it's part of the trio.
Also it's definitely not an all around deficiency, ph is right on and as I said been feeding fox farm Grow Big for weeks. Thanks for the reply though!

Sorry, coffee is still kicking in! Tiger Bloom is specific to flower and is mostly PK, I'd recommend their grow formula. I'm not remembering it's name...let me go search. I'll be back.

Ok, so the foxfarms product "Grow Big" would be full spectrum and have NPK along w/ calcium, magnesium, iron, etc.

Although, since you started in Pro Mix, I would recommend a nutrient designed for soil-less mixes. Pro MIx doesn't have any nutritional value, so You want to use a good soil-less mix formulat. Like Canna Terra (which is designed for Peat-based blends like pro mix) ...or GH's 3-Part Grow, Micro, AND Bloom. For now you would just need the Grow and Micro. I like GH's b/c they hit pH 5.9 upon mixing with most every what supply I have ever been on.

he wants to believe he has P def because of the pruple stems
P def shows as purple but more on the leaves fan leaves

purple stems is also a sign of N def

Thanks @lime73 ! ...yeah, I think it's astute you recognized the Phosphorus symptom, but now that I know you're in soil-less mix, it is clear you're probably deficient on everything...the Phosphorus is just showing up sooner. I have heard recent reports that Purple petioles is also associate with Magnesium deficiency. Still, end of the day, full spectrum nutes will cover you. It's time to pick a nutrient line you like and that's readily available. I'm always a fan of Canna nutrients, but they can be kind of exlcusive to specific hydro stores. So Cutting Edge SOlutions, General Hydroponics, Botanicare's Kind line all come to mind as good choices that aren't over-priced.

He does offer good advice I just want to make sure I have all bases covered.

OK I was just wondering because usually I just veg under a MH and I just switched to HPS because my 4 x 4 was overcrowded it was weird because as soon as I switched that's when the plant started developing these problems
