PPM question
Benasquellastarted grow question 4y ago
My PPM using pure rain water is around 70, what I read online is that I need to have somewhere close to 200/400 (EC 0.4) for seedlings, 450/650 (EC 0.9) for later veg and so on.
My question being how do I get these numbers? Just keep adding nutrients?

Well that's simple buddy. You need nutes. For a starter general hydroponics do a trio grow, bloom and micro. You'll need a PPM/EC pen. 2ml/l usually gives around 400 depending on nutes of course. So once you give the 400 ppm nute then say later CAL MAG at 300 or you can do a mix and tweak it to your liking. The PPM isn't a thing where you need to give all in 1 feeding once it gets that over the space of 24-48hrs. Sry didn't follow question right. This is how you can get there.

Rain water is never pure my friend.tds and ppm are measurements of amounts of nutrients that particular water can hold.If you are using a feeding chart through GPL or Advanced they work that out for you.

Whatever you are doing you are doing it right. Your plant looks spot on. So yeah. Don't worry about reaching the required amount of ppm in 1 feed, can be reached over few feeds unless your doing DWC. But soil and coco once your giving key nutes and right ppm over a space of time I said you'll be all good.

3-500ppm for 0-1wk or no nutes will work. 4-700 wk 2-4. When u start flowering 9- and can be pushed to 1400 max depending on strain some like more nutes than others auto like less nutes compared to photos. But them numbers u said will work 2. Be sure to add a micro to your list of nutes to help uptake. Happy growing, good luck.

Ph drop after res changePh dropped hard 24 hr after res change @ 60%. Had changed 1 week prior due to high ec + slowly dropping ph and added another air stone. Turned off the air stone for an hour, no change so likely not acid rain situation. Ph up’d, plant never showed signs of being unhappy. Thoughts?Week 12

Soil amendingThis 20 gallon pot is Fox Forest soil heavily amended. There are 3 plants growing and doing great. I want to plant new plants where the clover is growing as soon as these finish. My plan is to slowly add amended soil to the top. Will this work? Will the next round be successful?Week 5

Calculating Proper Runoff NumbersBefore I watered plants today the Ph was 6.0 and 1,000 ppm. I added nutrient solution of 6.2 and 1,000 ppm to each plant until runoff. Runoffs were 1,300 to 1,700 range. Ph was 5.9. Is this in the ballpark. If I add 1,000 ppm to existing 1,000 ppm and get less is that right?Week 10
