New Grower FIRST GROW w/ pic and need help with Lowering soil pH

[luey.v.kush]

Hi everyone, I'm have a few issues with my first grow and I was hoping that I could get some help from you all. Currently I'm growing 4 different autoflower strains which are: Big Bang, Vertigo, Pineapple Express and Cream Caramel. This is a small closet grow in a 4'x2'x'4 grow tent with a 250 HPS grow light, MTN inline fan with carbon air filter. I chose to use oF soil mixed with perlite and coco coir, tiered in 3gal smart pots. Currently I'm using nutes which I really don't know how I feel about these and molasses every other water. I'm about 5 weeks into this grow and recently have been having trouble with a few of my plants such as the Big Bang, Vertigo, pH level in soil keep reading 6.5-7.5 or > and I don't know how to control. I'm a little tight on funds after purchasing everything for my setup and I don't won't to waste time and money by letting this grow go down hill. So this is why I'm reaching out to you all for HELP and I hope that someone who has experience with these strains and similar issues can assist me. I want to thank you all for your time and I hope you all have a great day

You can lemon juice or vinegar to lower ph one tsp per gallon.start light and add a little at a time if you need to go lower.At five weeks ther is definetly somthing wrong.get your ph in line first How close is your light,what temps are you running how often do you fert.My c.caramel is at 39 days and is 32 inches high.Next time put germed seed directly into final pot,skip the tiering.

How are you checking your pH? Meter, test strips? If it's a meter, is it a good reliable one or one of the cheapies?

Im using a phmeter to check my soil it was bout 10 buck from the hydro store and as far as my water I check it using the ph drops with the capsule that came with it. I recently checked my soil ph again to one plant has a ph of 6.5 and the others are like 7.0-7.3 which I know is incorrect so if anyone can help me with other methods on how to lower my soil ph I would truly appreciate it
