Ok so my question is..when it comes to raising your ppfd. I know you increase nutrients.. what ranges of ppms are you feeding as a safe guide line if your running 1000 + ppfd?

I’m trying to get a top notch grow my next run. I don’t wanna burn any leaves if I can possibly avoid it. I’m coco...phing everything at 5.8 in veg / 6.2 in flower. Im
Using Athena nutrients. I follow the recommendation from there feed charts. Even when I’m using the light feed I’m burning shit.

I’m new member what Athena line did you get , your nutes prob ain’t fully dissolved my guess?
I got blended it’s the liquid version. I mix it pretty good and when it sits I mix it again. I only have problems during flowering. Veg my plants are super green.

Yes I do water to run off. I’m using coco should I water 2 times a day. Cuz I swear by the next day when the light turns on. My pots are bone dry. I’m running 7 gallons
Feed twice or more if your pots are getting bone dry, coco shouldn't dry out. When the dry out that much left over salts get left in the coco and cause EC spikes, probably why you are seeing burning.

Yes water them more frequently, you could use bigger pots or preferably feed 2/3 times a day in future, ime if you get a bit of build up it doesn't always wash it out with 10/20% run off, you need to rinse it out then maintain it religiously afterwards.

It's a safe bet if your plants are drying daily you’ll have salt build.

Sounds like my exact problem.My PPM runoff was at almost 1000. In this case do I water with diluted nutrients or just plain water PHd

It’s recommended to use diluted nutrients and not water. Personally I wouldn't bother with ph for rinsing but for the final feed after rinsing I would ph the nutrient.
