1st time growing anything help.

Hellothere

New member
Ive been having issues with leaves dying so measured my run off ph, it was like 5.3 on some of my plants. They are autos in 5 gal. I ran some water that was ph'd up through them until the runoff was about 6.15

Did I do the right thing?? Thanks.

Most of those pics (3-5) look like a calcium deficiency based on the browning on the interior of the leaves. If your PH was widely out of range, calcium is a common one to get locked out first. Now that you have adjusted your input water, try adding a good dose of calcium or cal/mag on the next few feedings. Hard to say if those leaves will recover, but you shouldn't see it spread on new leaves. If you do, the PH issue might not be fully resolved.
 
I was using cal mag with my feedings. Do you think the lock out was caused because the runoff was reading so low. May sound like a stupid question but like I said it's my first time growing anything.

All good questions. First, are you using coco or soil? I assumed it's not hydroponics, but correct me if I'm wrong. The answer will vary depending upon yours. It is important to PH the input water / feed, what were you adjusting that to? Was it adjusted after you added your nutrients?
 
Soil. Fox farm ocean Forrest. I've been ph between 6.2-6.5
Which is why I was so shocked when I read the run off. I've been ph the water after nuits cal mag first then I had a scoop sea grow 4-26-26.

So I basically poured through gallons of water that was ph'd to like 9 to get the run off to be above 6. Plan on adding nuits again. Next feeding

Yeah, I've actually hosed myself doing the exact same thing for the exact same reason using the exact same logic. FFOF for some reason comes out of the bag with run-off around 5.0 PH or less when starting with an input of 6.3 or so.... The ppm also comes out at 3500+... both of which shouldn't be right.

From my experience of doing what you described, I cause a massive and abrupt PH swing in the root zone, which led to issues down the road. I had leaf burn on the edges and brown spots in the middle. Not good, but I still had something to harvest. I'm not saying this is your fate, this is what happened to me.

I'm still trying to find the right data to explain the correlation of all those numbers, whether it is chaos theory or something moldable remains to be seen. I always will tell people to monitor their input but with FFOF and soil, I'm not so sure how important the output is, this is unlike coco. So my best advice moving forward would be to PH your input at 6.5 and do start adding nutrients back in with your next feeding.
 
For flowering, those may be good NPK ratios, but if you are in veg, you'll want to boost your nitrogen (the first number) In Veg Nitrogen is the one it wants more of out of the three, but in flower, it wants more of the last two (phosphorus and potassium) than it does Nitrogen anymore.
 
Well I'm like week 2 of flower on most so we Will see, they seem to like it so far but the lights are out now so in the morning I'll be able to see more.
 
To be honest it's hard to say if they more nitrogen, cause I didn't grow the plant an don't know when it started yellowing, that FoxFarms will hold them for 2-3weeks before they need any nutrients,
How many days old were they when you started feeding them?
They autos, they normally show pistils by day 15-30, How old are they now?
That flush should have helped , but it's hell on plants that late in flower, flushing in coco ain't nearly as bad on plants as soil.
ChadWestport gave great advice above, about everything.
Next grow you might want to try supersoil, or a one part nutrient like MegaCrop, it's easy to use, all you need is water then.You've done good so far, and your gonna love growing your on potent medicine. An them autos are the ticket for new growers.
I wish we had a good picture of them today,in good light, they look pretty far along, they might not need nitrogen, this late in flower, they might not need anything but maybe one more feeding, if that then just good water the last few weeks.
