HELP SAVE MY GARDEN!! Rust colored spots and deformities!

Hey need some help saving my babies! Rust colored areas from top to bottom of plant. Some have started to claw down with fan leaves that curl down. Starting seeing these issues right before my last feeding(PH was 6.2,plants are also in coco). I'm using vegamatrix nutrients and I did a full feeding of my micro nutrients and (average amount of nutrients of everything else)because I had some weird issues that I thought to believe was an iron deficiency. I am using RO water but I think my 2 and 3 stage filter needs to be replaced because the ppm before anything was reading about 220. Once I learned my ppms were so high I figured I had over nuted them so I gave them a flush with just water (220 ppm) and prime zyme. The day after everything looked worse and this weird rust colored was starting to happen to more plants. There was also some small deformities on some new growth causing the leaves to twist. I did some research on what causes this and stumbled on boron deficiency. It looks pretty similar but after the heavy feeding of the micro nutrients I would think that issue would be resolved. I also found another thread that stated that not enough microbe life would cause these deficiencies because there's no bacteria to supply the plants.Any info would be greatly appreciated!!!

Nitrogen(N)
Symptoms of Nitrogen deficiency include; red stems, small growth, pale appearance to the plant, and a rapid yellowing of the lower leaves that spreads up the plant. To remedy this particular situation, simply add a organic fertilizer containing nitrogen and monitor.

That's one I can see and second I think is
Potassium(K)
Another issue similar to Nitrogen and Phosphorous deficiencies, Potassium deficiency has similar symptoms and include, curling of leaf ends as they die and stretching of the plant. This can be cured by adding a organic fertilizer containing Potassium. Another fix would be to flush the plant with water and half the normal amount of a balanced NPK (Nitrogen, Phosphorous, Potassium) nutrient solution.



Try look these up on grow weed easy it has a long list of causes of these deffs, it should narrow down where you are going wrong

Hope it helps buddy

Looks like iron deficiency. Treat deficiency by lowering the ph to 6.5 or less. Avoid ferts that contain excessive amounts of manganese zinc and copper which inhibit iron uptake. hope it helps.

I think if you go by ppms you will get lost in numbers try see what the plant says.

Double looking at your pictures shows that she is hungry and feed some veg nutes with a little dose of PK (literally few drops)

This is best advice I could give tho again I never used coco allways soil.

1- RO water allot of people say to add cal-mag to your water.

2- coco the ph is like hydro not soil 5.8 is your aim for ph, and also to make sure your run off matches what your putting in,

here is a chart that might help
Save this it will come in handy.

3- if you are watering every day give them one day wet one day dry or two days dry even it will help the plant absorb nutrients allot better and the roots will spread nicely. And your leafs won't look like mastiff lol.
Good luck buddy

Hay man.

They looka like they need alot of food!!

Can you give more info.

How many weeks in veg
What and how do you feed them?!

bring that ph down to 5,8 little cal mag don't let coco dry out
