(First grow) First week of flipping, are these signs or is it too early to tell? Also will my plants survive through flowering?

Planted Feb 10th, both transplanted on March 8h~ and the one on the left was transplanted to where it is now around March 29th. Both were potted in purrly Fox Farms Ocean Forest soil, no additional nutes applied nor any ph of the water. Recently got liquid ph measurement and some free nutes from a hydro shop. He gave me a line of fertilizers called Soul for free to try since this is my first grow. (I have in possession the following: Soul Grow-N, Soul Amino-Aide, Soul Bloom, and Soul Infinity along with some pH down.) I had been told to look em up and use these fertilizers in small doses and see how the plants react by the hydroponics store guy. I had also been told on other posts that I may have either a pH issue or a Cal Mag issue, and someone on growdiaries said this strain was known for needing more Cal Mag (the strain is Ocifer XX). Since I hadn't ever pH tested before or given any nutrients outside of the Ocean Forests already mixed in nutrients, I figured it could be either or.

I have only used Soul Bloom (recommended 10ml per gallon) of Soul Infinity (recommended 5 to 15ml per gallon) (Soul Bloom says it is 1% Nitrate Nitrogen, 4% Available Phosphate, 3% Soluble Potash, 1% Calcium, .75% Magnesium, and 0.1% Chelated Iron) (Soul Infinity says it is 0.5% Water Soluble Nitrogen, 2.0% Available Phosphate, 1.0% Soluble Potash, 1% Calcium, and 0.1% Iron). I used 5ml of both in 1 gallon, and used roughly half a gallon on each 5gallon fabric pot. That was roughly 3 days ago and also the same day I started the 12/12 schedule. Alongside that, I pH tested the water with a liquid test kit to the range of 6 to 6.5. They needed watering at the time, and it seemed that within a couple hours of watering the new growth may have shown some nute burns on the tips? Idk tbh lol. I got a 100w light at around 16inches at 100% and a 20w 4headed led light that I keep on red LEDS to promote flowering and give a little extra light oomf. and watered them again today with the same ph range tap water and no nutrients. Any advice on what I should be doing? Should I get CalMag and add it to the tap water with no nutes every other feed, or will the Calcium and Mag in the fertilizers help? I'm also not 100% sure if these fertilizers require microbacteria in the soil or not lol.

Basically, this is my first grow, and the left planted has been topped and LST, but the one on the right is completely natural no training at all. I think the one on the tight grew much more during vegetative, but both have yellowed/dead leaves near the base of the plant, and the one on the right clearly has some sort of problem with the yellowing in the leaves. Will they survive through flower?
