Is my baby poorly?

If youre pH is really that low 5.8-6. I would consider adding a small amount of sink water to your mineral water to raise the pH up to 6.5-7. My sink water usually has a pH of about 8, but it depends on your area.

What Im trying to say is 5.8 is too low and you should find a way to raise it atleast a half a point.

my local store has mineral water at 6.8 would that do?

Also one of my girls is sativa and the other indica so I guess that is why one is thriving and the other struggling a little when they both get identical treatment. For a newbie it is a steep learning curve for sure.

Thanks guys for all you help and any to come in the future.

I bought an expensive ph tester and have accurate readings now. I was either doing it wrong before or the tester was crap. My soil ph is 7 and the run off is also 7.
Is this ok?

Thanks all

My poorly girl her leaves are better today and the brown stripe has not grown or spread at all. It looks like nute burn from some pics I have seen on here. What should I do?

As long as you are not still adding nutrients, then there is nothing else to do. The new leaves should start coming in nicely with the correct pH. The old ones wont start to look better, but also shouldnt get worse if you made the improvements.
