Deficiency help

These are my white widow autoflower at week 7 (first two pics), and my girl scout cookies autoflower at 8 weeks. Been giving them half dose of nutes depending at what there ppm were reading at after giving plain water. The girl scout cookies have been get 5ml grow big, 7.5ml big bloom, and 5ml of tiger bloom every watering. Ppm start at 900ppm and usually by the time im checking are down to 400. The white widow just got plain water last two feedings. Ppm went from 800 some down to 700 some which seems liles its consuming nutes slowly. What is going on? Using fox farm happy frog and fox farm nutes

Looks like calcium deficiency?

Idk, I think a few things, Maybe they got a little hungry and yellow or locked out and you fed them and maybe too much water? Look at these and see what you come up with.

I did give them to much nutes, but stopped that mabe two weeks ago. For the one it definitely is getting worst. I may have to flush her next time if she isn't eating much. I guess I got to test the ph as well next time, but have no clue how I would even fix that.

I haven't grown weed in soil yet.
I 6.5 ph my pepper plants ( peat soil ) at 400ppm full nutes.
If they are wet, let them dry out, you can't really fix that. Make sure all nutes are available at all times basically.
If the new growth looks good, that's about all you can do sometimes. Some of those leaves are toast, but you have plenty more.

I had the same issue at about the 5th week on 1 of my plants thru research I figured cal-mag deficiency which seems to happen on or after the 5th week. Calmag may work but I also realized my ppm runoff was 5.0 so had root lockout so using calmag wouldn't work. I did a flush then next watering I added dolomite which has calcium & magnesium and just ph watered till now on week 10 plant is almost ready for harvest and ppm runoff is at 6.8. On my next grow up gonna add dolomite into the soil from the start to alleviate the deficiency.
