PPM
Wscook07started grow question 4 years ago
when I mix my nutrients my PPM is only 120, When topping off my res. the PPM is at 40 & Drops to under 20 before topping off again. I have already burnt my plants a week ago but is that enough Nutrients? I cut it from 2 ml/ltr to .5 ml/ltr because of the burn (Advanced Nutrients)

Normally if you are seeing the EC drop the plants are taking more food than water which is telling you to increase the feed a touch. I tend to step up in small increments until I see the ECppm sit pretty stable.
If I am feeling brave i increase the ppm until I see a touch of tip burn then back off a touch to insure I am giving them the max they can handle.
Some people leave the ppm when they see a touch of tip burn and leave it there and actually call it ‘a perfect burn’. I tend to find in this game less is actually more👍

When to use terra aquatica ripen? Wait until they look ready to harvest or when they look like they will be ready in 2 weeks while using ripen?I'm coming to the end & I think they need a few more weeks at least, but I may be just kidding myself, thinking they're gonna double in size.
I'm gonna use ripen for the final 2 weeks with a 48h flash clean before & after, so should I start now or wait for more amber trichomes?

Soil pH not adjusting even after watering pH water.So Far I've been 6.5-7 pH water, & organic ferts BioThrive Grow, Bloom & CalMag. The soil pH doesn't seen to go any below 6.5; even though I've been feeding 5 pH water to make it lower. Why is this happening? What to do? Does organics in the soil auto-adjust the pH all by itself

BioThrive Fertilizer Water pH & PPMI tested my BioThrive Bloom+CaMg fert water for the first time ever today; I've been feeding 4.5 pH & 340 ppm fert water solution; Soil pH is 6.7-ish per the Rapitest meter. Should I add pH up solution to make the fert water 6.2pH? What if the soil pH increases over 6.7?

Nitro toxicity and calcium deficiency. Should I flush?Little pas halfway through flower and appears I have nitro toxicity, could this be a cause of my calcium deficiency I have been dealing with? Should I flush it or would that continue the degradation of the calcium?

Calmag overdoseI was stoned and accidentally added way too much calmag to my distilled water when watering yesterday. I meant to add 2 ml into a gallon but instead added 20 ml. I poured 3 gallons of Distilled water through today trying to dilute. Am I screwed now? Is my plant going to die?Week 4
