Went to bed last night and plant appeared to be fine and woke up this morning and a couple leaves looked like this and new growth was messed up. I watered yesterday with ph balanced water only containing cal mag. Strain is GDP. Ffof soil. 75-77° during day 68-70° during lights off.

How much run off do you have?

Have you given them any additives?

You didn't mention a substrate (coco maybe?} or nutrient strength?

Not sure the exact amount, water until it begins running off and quit. Gave them 1/3 of the recommended dose of foxfarm big bloom, boomerang, and wholly macreal. Foxfarm ocean Forrest soil.

The amount that drains needs to a reasonable amount I'd guess 10/15%, feeding until it runs out of the bottom isn't sufficient, and if it's left sitting in ie not drained it'll make it worse.
Feed enough to get to get run off and test that?

Ok I don’t let them sit in the runoff but will begin watering more and tear my runoff. Thanks
 
How old are the plants from seed? We’re they transplanted into FFOF or Sis you start there? I’m gonna take a wild guess that they are young and didn’t need the nutes you gave it already. I would just water when needed and make sure to keep ph at 6.5. I say that because being new to growing you have a .5 on your side before you really run into ph issues.
 
Run off on the way out is most likely going to be higher than what’s going in. At that size they should be around 400-500ppm for feedings.

Second week of veg. Started in jiffy pod then transplanted into this. I put BlacK Gold seedling mix potting soil all around jiffy pod a couple inches and the rest ocean forest.
 
Watering in between feedings can help run out the build up in the bottom of the pot. Maybe even watering with plain ph water first til u get a drop or 2 of run off then add nutes water. That’s a method I am using now with the end of flowering coming up. Gonna be my alternative to flushing.

FF soil strikes again.

The bottles nutes are controllable but the soils are just becoming more problematic by the day.

I use FFOF and never have problems. But I also don't feed anything for weeks when I use it. The FF nutrient feed chart has people feeding week 1 and and up to 2 EC week 2. That might be fine in an inert media like Promix or coco but not in a hot soil like FFOF.
