2 chocolates 2 white rhino, in ffo for about 6 wheels, fed for the first time a week ago. General organics bloom, cal mag,bio root,big bud,bio marine, 1/4 strength. Just today this popped up on my leaves, these being the worst, but I see it on a cpl other leaves beginning to look weird. My lights were at 17” moved them up to 19” (maybe light burn) and I have been bending them last cpl days. Today was a water day so I watered to good run off ands it’s about 6.5 ph
What’s your PPM of your feed?
Some of those blotches may be genetic anomalies.

But it’s on 2 diff strains, I just got a meter, hate these things, hell the ph meter wore me out. Lol
If it was nut burn, I thought it would be more wide spread? First time grow
Leaves seem yellow, so I want to know if you are under feeding. If PPM below 900 you should think about raising it to 1100PPM. But since you are having issues with PH? What are your input/runoff pH as well.

And do your spray anything on the leaves?
I think my ph is good, before 6.o run off is 6.5
I was misting the plants, but quit a cpl weeks ago
I’m seeing a P/K deficiency in the way there’s no sheen (K) and the bent leaves (P ). Low N would be much yellower. Are you in flower cycle? If so, a touch more bloom and like WickedAle said, a touch higher PPMs’. I’m floored at 1300 with a good balance of NPK. (hydro) any imbalance and they’ll burn. CO2 too.

Flower soon, working lights down, now at 14,8, New light coming Thursday, maybe flower next week
Ok I got 5.72 on meter, x .09 =.5148. Sound correct?
TDS meter
I don’t know EC conversion to PPM. This is not a PPM reading.

They look underfed, they should be very green and healthy in grow cycle, that’s why I was wondering if they were in flower. Flower cycle is when things get tricky and hard to diagnose. Still they should look waxy and green with no yellow whatsoever in grow cycle.

Hmm, ok I’ll do it again
They yellow what I was keying in on, but since I don’t use EC I can’t tell if the reading s are right.

I don’t use electric conductivity either, I’m a PPM guy.
Got this online. If you are at 0.5 you are 1/4 strength. You need to move to full strength. What are you feeding compared to a schedule for those nutes?
In soil I don’t go any higher than 900 PPM, and that’s run to waste.
Ok ppm is 813, if you multiply it x.9 for salt it is 731
