Persistent low pH I am growing for the first time in coco coir using mineral fertilizers. I noticed that the runoff pH was very low (5.2), so I flushed the medium with water five times the volume of the pot at pH 6.1. However, the runoff pH remains at 5.2 and never increases!

Giant autoflower with slow flowering I have this automatic CBD plant from FastBuds, which is now 95 days old. It has grown much more than expected, and the flowering process is very slow. This has never happened before. Does anyone know if this is normal?

Giant autoflower I didn't expect this Fastbuds CBD 20:1 autoflower to grow so big. I'm having issues: can't get past 600ppm with Remo nutrients without causing burn, but lower leaves show phosphorus deficiency. The plant is 12 weeks old, and the buds aren't fattening up. Grow 80x80x200cm

Magnesium deficiency?This is my first grow in coco. I have seen some responses on this site saying that it is not possible to see magnesium deficiency before 30 days. What could it be? How many PPM of magnesium sulfate should I add? Last week: pH 6.1, EC 0.7, 26°C, 56% humidity, and 430 PPFD

High PPM levels using Remo Nutrition Hey guys, good evening! Right now, I'm using Remo Nutrition and following their nutrition chart. We've reached 2ml of each product, which results in a PPM of 1900. Is it okay to stick with these doses?

Deficit, help Seeking help for three plants with magnesium deficiency due to low pH. Using Remo nutrients and BigFoot Mycorrhiza initially. Flushed pots with pH 7 water, but runoff pH remains at 5.8, dropping to 5.2 after a week. Requesting advice. Output ppm matches input, VPD is correct.
