Plant Concerns / Leaves Nutrient Burn?

Please help! First time grow!
Female plants Indica/Sativa
Ebb/Flow Setup in Hydroton/fabric containers. Starting flowering phase today.
Using Advanced nutrients Micro/Grow/Bloom with distilled water. Changing water weekly.
pH in the 6’s. Humidiiy around 50%, Temp 77, light is low watt, LED.
Roots look nice and white, water looks clean/clear, cleaning out resevoir weekly too.
Last week was advised could be nutrient burn, diluted out water with more distilled.
Trimmed some bad leaves.
It looks like its getting worse. Only on lower leaves. Rest of plant above looks green and healthy! !
Thank you!!!

If you don’t have a digital ph pen it’s pretty much a requirement for hydro. As is a tds meter.
And too. Ph should be 5.8 for ideal.
You can let it drift a Couple points either way.
Cal mag is also needed when using distilled.
And welcome to I❤️GM.

@jambi1214. From what I can see in the pics. Not too bad.
Few marks and spots.
If you can get your ph down a bit I think your leaf issues will clear up.

Too high or too low and the nutes may be there but if the ph isn’t correct then they can’t eat them.
Should be 5.8 - 6.0 for hydro.

Im asking how would I lower the pH of my solution?

You would have to add a ph down product to your nute solution to get it to settle into the correct range.

You can buy pH down or use white vinegar.

Sodium bicarbonate will work for pH up.
