Been doing a good watering. My ph going in is good. I adjust my ph this last watering to 6.9 for my runoff last water was 5.5. Not sure why I have all yellow leaves and in the too with brown. Been feeding as levels needs. In week 6 in happy frog. My light is 18 inches up. The yellowing i noticed a few days ago. Getting worse. I feed Nutes every other watering. I write it on my callender so keep track. This grow has been crazy.

You need cal-mag. If you’re using it double up. And you should be good. Watch the new growth. Your catching it early so don’t sweat it. 
I think he has more going on than cal mag deficiency. His runoff was 5.5 using 6.9 going in. Wonder if the early feedings locked them out with that ph……
Very well could be so probably flush to reset? 
If you’re using fox farm nutes you have to flush 3 different times during the grow. It’s on the grow schedule
I definitely would to reset that media, flushing soil sucks but it’s the only to get those salts out now! I’d run 6.5 ph water thru them until ph comes up to at least 6.4 and follow with a half strength feed as the flush will flush nutes out too. Then let them dry out before resuming feed at less EC than before.
I also just noticed he’s in flower , so if it’s six weeks as he said, it’s an auto so yield will suffer for sure.
No I’m using lotus
So go ahead and fluch tilli get a 6.4 ph runoff. Then use half dose of my nutes right after flush then let dry. Or wait till dry then run half nutes. I am using lotus at bloom 1.5 tsp boost 0.25 tsp right now.
I was wondering that. This grow hasbeen hard for some reason. I forgot toputits ackoset grow mytemp and humidity it good though
Feed them as soon as your finished flushing, then let them dry out.
Actually i had used fox fox nutes at the begining and got lockout i believe. I hated themso i flushed and switched to lotus. But i didnt do a good flush like i should have. Was told only 3 jugs Guess i need to do a complete flush then. Like 15 jugs
It can take up to 5 times your pot size! It’s a job.
Ok thank you. Ive done some research but hard to find. Do a few take a break do a few take a break and so on. Thank you. I will do this flush then. Ive been told its a job. I had to add more soil when did a 3 gallon flush
Just keep checking runoff numbers as you flush, you can see them come back in line and stop flushing and give them a half strength feed right after, PHd at 6.5
Thank you Growdoc. I appreciated your help
Anytime bro!
Do you think the tops will recover from this. I think the yield as said earlier is gon a be effected by this.
The damaged leaves won’t recover.
Watch the newer growth for improvement.
I wouldn’t use the runoff’s pH as a criterion. If you’re trying to flush salts, ppm makes more sense.
Try to get 20% (or so) of the amount of liquid you add back as runoff each time and measure its ppm. You’re looking for the ppm to stabilize. When it does, you’re done.
Don’t be surprised if it drifts down and then jumps up. I believe that’s a sign you’ve begun dissolving the accumulated salts, but that’s just my idea.
