First grow and can’t seem to figure if this is nute burn, deficency or ph issues?
Flower Week 3 of LSD auto
Growing in FFOF ph in 6.4 runoff at 5.8 slurry at 6.8.
Been trying to give it cal mag but it doesn’t seem to be getting better.
Using GH flora series.

More info needed for sure. Generally speaking, looks like a calcium and start of potassium deficiency. Real question tho, is this caused from lockout/ph issues or not enough nutes…also you will here alot of growers say calmag calmag calmag. But if your overdoing calmag, it will actually block your pk nutes and screw up your ph and nutrient balance. Runoff tds numbers would help alot. Not sure if flora series requires a occasional flush like fox farms but would also check that out.

Once a calcium or magnesium deficiency occurs the leaves will not improve so you need to see how the new growth is responding.
I would cut off the worst of the leaves since they would bug me and make it harder to determine whether the actions I am taking is making a difference.

After a closer look @CMichGrower , i don’t know if I would go crazy with the clippers as u suggest, as the op has orange spots on alot of leaf.
I’m thinking the op needs a flush but will wait for the numbers.

If your feed was 290 and she’s coming out 900. Then you have plenty of nutes. Are u using any type of fertilizer in addition?
I would flush it then refeed. Especially if you have been giving it call mag as your calcium seems to be locking out due to low pH. I would flush then pH up till my runoff hits 6.

Heres how i would proceed if were me. I usually do not worry about low ph out untill it shows a problem which they do. Calcium in soil start to not be absorbed below 6.2 if memory serves. So i would flush with 6.8 ph water. Quick side note, you do not ever wanna go above the ph range of soil (6.3-6.8) to compensate for runoff. I would not go crazy dumping 3x the volume or any of that but i would give a good 3gallon of straight water at 6.8 followed by a feed chart feed immediately after to refeed. It is only overwatering if not allowing to dry out, not too much at once…keep your feeds at 6.8 for a while with good runoff and keep tract of in and out and go from there. You dont want the girl stunned at this point of flower bc it will affect end yeild no doubt.

Okay I just flushed it and brought the pH up to 6.1 and ppm at 450 runoff. I’ll keep tabs on it the next couple day and will update you all!

I hope u refed her immediately after the mini flush

Yep I made sure to refed with the feeding chart hopefully she’ll get better with the new pH.

Good job, I bet that solves your problem.

Looking any better?
So after I flushed it the next day the rust spots became worst, but I wasn’t too surprised because of the delay. The day after that the rust spots completely stopped spreading! New leafs are good looking without spots.
So not sure if the spot will disappear or not but it hasn’t gotten worse in the past couple days.
Because this is my first grow i’m not too worried about quality, just trying to make it to the end of the grow.
Here she is just with a lot of rust spots.
