whats wrong with my plant have pics

so my ph was high 4 a while in the beginning from seed like 2 weeks ago since then ive got it down between 6.3/6.5 in soil leafs dont have that soft wet feel on any of the leafs on the plant was thinking mag but it started at the top of plant and the lower growth is fine she is being fed organics at low levels any input what this could be and what i should do 2 help her thanks any questions ask away

what kind of soil. what nuit brand. whats a light applaction ?

On pic 2 you can see that what ever the problem was it appears to have been corrected.
The new growth looks good!
Problem shows - fix problem - new growth shows the fix has worked or not. It takes 5-7 days in soil for a correction to show and always in the new growth.

What organic are you using? How often and how much? Do you supplement with a microbe tea?
Ph in soil is self balancing,,,,,but seedling/young plants should be paid attention to for a bit.

Keep us posted on the new growth.

thanks darth dank an dr who soil im using is light warrior and pro mix 50/50 mix lighting just using flos i do have HPS lights thow nutes using advanced nutes iguana juice at 4 mls a gal.once a week there due today 4 a feeding was gunna bump it up to 5mls a gal. should i bump that up more its a kush strain and waiting for my organic b to arrive soil is self balancing ive heard that many times hear and there my water is like 7.7 without nutes are u saying i dont need 2 correct my ph before water/feeding im asking cause i wanna hear more about this topic A.N says i should always correct but i hear lots of peeps doing well not correcting

I use general organics and it lowers my ph.water is 7.7 and my nuit solution is 6.4. Also maybe too much water at one time, seems like you should water more often ? 2 times a week half the water ?
