This auto is a month into flower and looking terrible. Using distilled water with 10ml/gallon Cal Mag under Mars 2 900 led with Fox Farm soil and FF trio at 50%. Any advice appreciated.

Looks like the typical calcium deficiency. I see you using a lot of cal/mag, were you earlier on? Those leaves won't repair themselves, most likely they'll continue to die. They always do for me... If she was my plant I'd ride it out and not worry much about it. Your giving her plenty maybe a tad to much nutrients if your giving her 50% strength every feed. Do I see seeds in those flowers?

Thank you- started Cal Mag at 5ml and this happened so I increased to 10ml a week ago. Can't tell if it helped so should I go any higher (no pun intended)? The 50% FF trio feeding is at once per week so I will decrease a little. Hate seeing the auto so out of sorts. Will the crop be ok?
 
:toke: Hmmm, FF soils set my alarm s off these days,.. many reports of badly acidic pH in bag these days! I need closer pics too please, just to confirm; Ca and sometime P deficiencies can look a lot alike, and certainly can happen at the same time,.. my worry is if the soil is off-pH badly enough to cause a lock-out type defc.,... do you pH adjust your nutes and water, and have the pH and hardness of the water as well? here's the catch: getting an accurate reading of in-pot pH... A quality soil pH probe like the Accurate 8 is the ticket, otherwise, you have to do the run-off method and calculation, a crude estimate at best,... that method is in this section in the highlighted area above this one,... until we have some idea about the soil pH, it's risky to advise anything.. a pH lockout will worsen if you add more nutes/supplements into the soil,....

Thanks for your response and yes, the water and nutes are tested and go into the soil around ph 6 according to the test drops and the yellow color of the solution. The runoff also tests yellow around 6ph. Others have said this is a Ca deficency caused by using Mars 900 LED lights and distilled water, so over the last week , the Cal Mag amount has been increased to 10ml/gallon from 5ml. Do you think distilled water is a problem and what soil would you recommend?
 
...get your water and nute soln. pH's up to 6.5 at least, to counter the suspected lower acidity in there,.. yup, part of the low Ca issue is the Di water, which has been stripped of the buffering minerals, mainly CaCO3,... LED seems to cause increased demand too! What's the distance to from tops to lights? This play a big part in a variety of issues,...
Roots Organics makes decent soils, though I recommend adding a bit more lime to them,.. Vermicrop I hear good things about,... Black Gold is OK, but again, before planting, always test the soil's pH,...
 
The LED light is about 12 inches from the top of the plant. Here is an updated photo where you can see 2 trainwreck autos looking sick and two plants in the back looking good. Same light, same everything but planted 10 days apart from the sick ones. The solution ph is around 6 based on the drops on the test kit turning the solution light yellow. The big plants are 60 days since planting. How much longer should they go? Cal Mag was increased to 10ml but it seemed to turn the plants more orange under the light.
