I had a quick question(question at end) I can't seem to get a answer for. I am a beginner grower in his first grow, so heres the issue and question. Plants are 1 month old, only 1 of 6 is sick. Soil Runoff PH was 7.3 and I feed on and off at 6.3 so I believed its getting locked out. PPM in runoff was 4800 ( ouch ) I flushed it with PH water of 6.3 till PPM read about 750 ish no but no change in PH of the runoff. I decided to try to lower to PH of the soil using aluminum sulphate I bought from the store. My normal water PH is 8.3 so I always PH to 6.3 before giving to plants. This tap water that has NOT been PH,d to 6.3 turned out to be 4.4 with the aluminum sulphate in it. I added it asap since flush was last night but added it slowly. On the label it says 3/5 tsp per L of water so I used 4, my target soil PH is at least below 7 but the runoff from the 1 L watering left PH 4.4. My question is do I PH the water to 6.3 after,before or at anytime with the added aluminum sulphate before adding it to soil to attempt a 1 point drop?
Help question on Amend soil aluminum sulphate ??

What soil are you using? Promix, coco, slow release nutrient?
It was the only one I started out in a solo cup with golfgreen potting soil. They all came up fine in jiffy pots except this one, she grew quick. Roots were coming out of the holes I made before any others and it was the last seed planted so odd. Repotted into 5 gall with foxfarm ocean forest. Nutrients being used on/off were rapid start root enhancer at first and atm she had 2 small doses of grow big.
So first 2 pics are what the good ones look like and the other 2 are different views of the sick one.
I did add on a inch or so more soil on top to make it more stable for the plant but cant water till it dries up from the flush. I'd like to add that after the transplant I only watered around the root area and it was never enough to get runoff to check since small plant big pot but shoulda been enough for it. Only now my other plants are hitting 1 L waterings for 3/4 days till it dries.
