PPM i EC ph
Ziooomoooleeekstarted grow question 4y ago
Hi there. Important question. What should the optimal PPM and EC of the solution be during the first week of flowering? I have soil. And I'm using Advance Nutrients fertilizers, which lower the pH of the solution to 5.6 pH. Should I increase the pH after preparing the solution to around 6.5 pH? Please respond quickly.

If I'm using a solution with a pH of 6.5 and the plants look fine without any signs of deficiencies, then it shouldn't be possible for the soil pH to drop to 5-5.5. It should be maintained at 6-6.5, so the solution should always be at 6.5 pH, and only the PPM and EC values should change, right? Let's say by +100 each week during flowering. For example, in the first week of flowering, PPM is 800 and increases by +100 weekly, reaching a final value of 1100-1200 PPM.

I stopped giving my plants Plagron Silic Rock from mid last week (week 13, week 5 flower). Can anybody tell me if I did right to cut it in flower or does anybody has experience using this nute until the end of their grow? I think this nute is just for veg and early flower.

Substitute for liquid hydroponic nutrient solutionsThose solutions (like Hesi Hydro Growth) seem to be ridiculously overpriced, like 10€ for 1 liter fertilizer solution which consists of mostly water itself is a total ripoff in my understanding.
Is there a substitute for those heavily overpriced nutrient solutions?6y ago

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?

Dutch Pro Nutrition AmountsNew to Dutch Pro nutrients and Im loosing my mind!

Diamond black vs. Diamond nectar by GHEHi everyone,
I've read Diamond nectar is very good. But I noticed there is a very similar product from the same brand: diamond black.
I was wondering what's the difference, and which one would be the best in an indoor grow in coco with high frequency fertigation.

TDSI’m on week 6 today. Is this a good TDS reading or should it be higher/lower? I have the unit set to 500 ppm . I used 5 ml/gallon of tiger bloom, 2 ml/gallon of bud candy & big bud. I also added 1 tbsp of epsom salt to lower the ph in my soil.
