Cheap PH down?

smokeyspartacusstarted grow question 5y ago

Is it just me or is GHE/AT PH Down very diluted? I started with gGrowth Technology which is 81%. TA PH down has nothing stated on the bottle... What do you use as the cheapest way to get PH down in circulating hydroponics/DWC?

Not sure if it works with hydro/DWC but citric acid is a cheap pH down. It’s water soluble so I’d imagine it be ok. Worked great for my organic grows.

When to introduce nutrients to coco / perlite and how to water seedling?Hi!! I am doing my first ever grow. When should I introduce nutrients to my plants in coco? They have just sprouted and I was only giving them some water with H2O2 at a PH of 6.2. For a seedling, do I need to water until I get runoff? Thank you!

Add Nutrients after 2-4 days of sometimes heavy rain for an Auto. Yes or no?I just had 4 days of sometimes heavy rain, 2 days in to it I added 1/3-1/2 my 3 day nute routine. We had 2 more days of sometimes heavy rain. Im in week 8 of an outdoor potted auto grow and I have 3 days of sun coming. Should I add nutes before they dry out? Bud rot from rain?
