HELP! Second time Auto grower(indoor)

[SpiralDropkicks]

One of my plants are growing exceptionally has a good color I was going to start low stress training it since it was too late top but I’ve noticed spots and discoloration on the leaves so I put everything on hold Acquired some Cal mag and used it with my feeding with less than a quarter nutrition and distilled water. The other I proceeded with regular feed plus cal mag and she looks pretty good to me, but this other plant is giving me the hardest time. I assume the soil is probably hot so I also did order FF Sledgehammer. If somebody can Please take some time out of their day to help me out I’d appreciate it!

Edit: Strain is Critical Purple Hybrid 60%I 40%S.
Soil tests at an even 7.
Using 50/50 FF Happy Froge and Ocean Forest.
Nutes I've been using (only once using 1/4 of amount) CalMag and FF GrowBig.
2000w LED Light is 18inches from plants.
Plants are 19days old.
temperature is at 74F.
Not sure about humidity but is definitely not humid.

Looks to me like the leaves are touching the soil which is burning them a little. I'd cut those off, as for the wrinkles and leaves canoeing that's normally a heat or humidity issue

[SpiralDropkicks]

Those leaves you see touching is the first two single leafs so I reckon it wouldn’t harm it much. What about the other leaves that are spotted or crispy tips do I trim those? Or just leave it be?

[MeEasy]

I would only cut those touching the soil, the others are probably connected with the use of distilled water you can use distilled but you have to add calmag to it or you'll have problems. I don't use it so I don't know how much or if there's other stuff you have to put in.

Why distilled water? Distilled water is acidic by nature (as it takes on CO2 the PH drops), how do you PH it? (your PH meter cannot measure distilled water, there is nothing in it to measure)
Speaking of PH, what is the PH of the soil?
Need input!

[SpiralDropkicks]

I didn’t know that. I assumed since distilled was absent of everything it would be safe. What water do you recommend? Also the soil Tests at an even 7.

I catch rain water (Ph 7.1), also restoring my well so I dont have to use any tap water in the future.

You should be testing the water PH more so than the soil. If the water (and added nutrients) isn't at the right PH the nutrients don't get taken up by the plant. You can feed it everything under the sun but if the PH is off... you get a green plant without healthy buds. PH levels differ for soil as they do for Coir. If as you say it is soil, then 6.5 would be better as it is midrange aim for between 6.0 and 7.0.

At that growth stage hacking off leaves won't solve your problem as mentioned above...leaves are the solar collectors... the more the merrier. Plant training is the better way to go.

Are those the same strain? Are they photos or autos? How old are they...........we need this infor when you ask about your plant.
