Grow Mediums New to autopots, needing help

[willywilson81]

Hi guys and gals,
Recently started this great hobby again.

After looking at the awesome results people have gotten from autopots I took the plunge and got the 2 15ltr pot system. I am only running 1 pot at the moment with a female seeds lemon kush photo I had veging whilst a couple of autos finished up.

I only mix up 10ltrs of water at a time with canna a & b @1ml per ltr water and ph'd down to 5.6. She took of like a rocket for the first week once the res was on but I have noticed a couple of spot Mark's recently and thought I'd see if anyone can diagnose what I'm missing/doing wrong.

My medium is a mix of canna coco natural and biobizz light mix at 50/50 with about 1.5inch of clay balls in the bottom.

Any help will be gratefully received. Thanks in advance.

Looks kinda like calcium deficiency, but not exactly? The issue may be ph. I think sub 6.0 levels are ok for hydro but coco and especially soil works better in the mid 6’s. It could be the cal level in your reservoir is ok, but the plant won’t absorb enough because ph is low. Absorption happens better the closer ph gets to 7.

Think you might have posted in the wrong section. This looks like a deficiency, not an AutoPot issue. @Waira is the man to diagnose sick plants.
You'll get better answers from the infirmary. can we get a Mod to move this thread please?

Looks like burning from water droplets to me, but I will be interested to see what @Waira has to say. OP could help by filling out the infirmary form for him.

Good luck.

:smoking:-- yup, need more info on this one,... @willywilson81 the info form is at the Infirmary, top section is where the Sticky articles are, it's in there; just c/p it into a new thread in the patient section below,...
This could pass for P defc or Ca, at this point,... they seem to show a fair amount of overlap sometimes, and show up on the same levels of the plant despite Ca being poorly mobile and P fully so,...

Cheers guys. I increased my ph to 6.2 in the res and things have sorted themselves out. I'll post in the correct forum next time. Sorry.
