Like we were saying, the term overwatering is usually meant to mean watering too frequently. By watering too frequently, the roots don’t get a chance to breathe, creating the increased conditions for root rot.
If you’re following the Fox Farms feeding schedule, I believe most who use it say to mix it at half the amounts given in the feeding chart. And then to flush the built up salts out periodically (per the feeding chart) with the Sledgehammer product they have. That product was hard for me to find when I first started growing and was using FF nutes.
Btw, a flush is running 3 time the size of the pot of pH’d water through the soil to flush out the built up salts. So, a 3 gallon container = 9 gallows of water.
I have heard that several times, but I do not know how to achieve it. That’s my problem with watering. I cannot tell the difference betwixt overwatering and underwatering. Is there a simple way to understand and master this? 75 dead plants is telling me I’m phuquing up pretty royally.
Jawz said it best. I too use the weight of my pots to determine when to water.
Use the same size pot as you are growing in. Fill it full of soil. Pick it up. Feel the weight…Now water that until water starts dripping out of the bottom. Pick it up again. This is simply the easiest way to determine when to water. Do you record stuff? When watered, how much, ppm’s going in and pH?
PPM are Parts per Million or TDS Total disolved Solids. This is a measurement of how much food is in the soil
Yup, none of my broccolli produced broccolli… @DesertIndividual you never answered the location query, Are you moving the same plants in and out regularly?
Experience, experience, experience. (And maybe posting pics here and asking your fellow growers )
No, really, it’s sometimes hard to tell. The signs of overwatering and underwatering are similar with the droopiness you’ll see. I’m still learning, every grow, but I tend to think that when they overwatered, the leaves themselves droop and look “soggy”. While when they are thirsty, the stems of the leaves will droop first and curve down with the weight of the leaves. But that’s just my obsevation, nothing I’ve actually read.
I don’t normally see signs of overwatering these days unless I’m growing an unfamiliar straing that doesn’t suck up the water as rapidly as its neighbors and I’ll have to start staggering my waterings at that point.
As far as over or under nuting? All over lightening or yellowing is a good sign of under fertilizing. And then there’s this.
Oh, they are aware of it. That’s why they sell Sledgehammer. You mix it up in a gallon of water, pour that in you soil, wait about 15 - 20 minutes to let it break down the salts a little, then continue with the flush. When you do this, be sure to mix you last gallon with a half feeding of nutes so the roots have some to feed on while you’re waiting a few additional days for the pots to dry out again.
