Nutrients, what was your dosing? May need to flush the plants.

I think a flush is a definite there. How are you measuring your feed

Don’t feed anymore just now as you need to check your runoff PPM and PH. Feeding blindly is a recipe for disaster my friend

You are not following the nutrient calculator, should not be giving big bud and overdrive at the same time, that really spiked your P&K, got to be careful with bloom nutes or this is what happens.

High intensity lights, along with high temps and a high nutrient load all contribute to nuke the plants. High heat cause increased liquid consumption (uptake), and concentrates the salts to cause burning.
Looks bad start with H2O2 in your water and dont use fertilizer.
What the best way to check PPM? I don’t even know what that is… Newbie, sorry
You can buy meters to check it. Have a look at the Apera type tds/ec meters. You water until you get a small amount of run off, lift that using a syringe and test it. There are given values depending on what stage you are at in your grow. It’s a science in itself
