fan leaves dying in veg starting limp at the tip them brown and crispy.thinking P def

hi there..kc northern lights x4 at 8-10 days my seedlings first leaves started going limp at the tip dark then crispy light brown they are now 25 days old and its slowly working its way up the fan leaves its now effecting the 3rd and 4th set of fan leaves its not nute burn because it started b4 i start feeding,,, im thinking phosphorus deficiency but with out the purple in it maybe because its in veg there is no purpling???
i started feeding at 13 days old with AN jj micro,grow,bloom,,, 0.5ml per liter of each plus seaweed, 2 days later i transplanted into 7 liter pots feed them 1ml grow 1ml micro 0.50 ml bloom, then at 21 days 2ml grow,2ml micro,075 ml bloom, its been 4days till last feed need to water now but i think i should give them more bloom as it has the most P in it , its not stopped but think its slowed up tho(the last feed hasnt properly kicked in yet)
canna pro plus 4 part to 1 part perlite ,,plus 10gm blood fish and bone and 10gm lime at transplant
using rain fresh water aswell ph at 6.7-6.8...
im running 2x 180w LED lights in 80x80x160 tent plus extraction plus fan inside
im thinking either phosphorus deficiency or zinc maybe??
some 1 plzzzzzz help
pics attached

any 1 on earth tonight lol ????

Are you sure it is not some kind of lockout caused by a bad ph?

your feeding them bloom booster ? major mistake . it will burn the plant fuck it up . not going into detail why, just use the correct fertilizer for the proper time . get a veg fertilizer.

lol i ent using booster mate, its a part of a 3 part mix you got to use the bloom part to make the rite ratio with out it you would get hardly any P in the mix// grow NPK = 2-1-6. micro NPK = 5-0-1. bloom NPK = 0-5-4 // so you still got to give it a little bloom to get the rite ratio besides like i said it started before!!!! i started feeding them and my ph is perfect

He is using bloom.
It just looks like you were feeding them a very weak nutrient mix and now that you have upped it, they are responding. I don't think it was lock out, just a lack of nutrients.

i am going to have to agree with nute burn , solution seems a bit to strong are you give what you started in he beginning or are giving 20 to 25% stress of what was stated?

Do the tips of those leaves sit on top of the soil when you water?

OMG!!! the problem started B4444 i gave them any feed this is the third time ive said it lol and no no leaves are touching!!! i really dont understand it...it is nothing boveous ,,, im a pritty good grower and i just dont understand

guess you are just a terrible speller? sorry i could not resist.

image 5 looks just like zinc def on the deficiency chart

I wouldn't be concerned if its only limited to those older leaves. If it was all over I would say high phosphorous but its just the bottom leaves.

the bottom 3 sets of fan leaves are effected tho,will it still spurt??
