Cheap PH down?

smokeyspartacusstarted grow question 6y 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.

Confused about PPM and pre-amended soil and knowing which ppm to sart feeding.What should my ppm be when I began to start feeding nutrients? My soil has nutrients pre-amended for the first 3 weeks, it's been three weeks and it's 1800 (my tap water is 200). That seems pretty high for 3 weeks after the plants have been in the soil. Thanks!

NL Auto Day 56 — after major nutrient imbalance: I don’t know how to rehabilitate or determine when ready to flush and harvest... Suggestions for a n00 I committed a n00b mistake & got the nutes all outa whack during bloom. Now the fan leaves are yellowing and brittle. The stigmas are also turning orange, but I don’t see ANY amber trichs — maybe just burned? I fed again, but don’t know how to tell when to flush for harvest. THX!
