i'm out on this one as i don't do bottled nutrients. two part salts are my jam. plus, OP is in a weird hybrid media which is just asking for all kinds of issues. @ComfortablyNumb has guided OP in the right direction, but I can't offer anything of value here. Good luck.

i flushed my plants with 7gl of water and measure the run off ppm, 1st gl run off was 2600 ppm, after 7 gallons it went down to 400pmm (my tap water is around 350) and ph was 5.8.

Did'not have golf balls but i used this pvc pipes to raise my grow bags.

Hope they recover soon ..
Thank you for all the help.

You flushed on last Tuesday. When did you water/feed after that? What nutrients did you use if any? What height are you lights set at and what type of light are you using?

This is one plant, right?
Find out the temp of the root zone. Inside and out.
Lets have some close ups of a couple of the dead leaves.

Dynagro is great stuff. I've used their Foliage Pro with good success and have no reason to believe their grow and bloom are any different.

Been using Mr Fulvic for almost a year and it works great as well. Plants seem to love it.

That is phos big time, but why?

Feed it some grow big and water it until just a drop of runoff come out. Not too much grow big. 1/4 dose.

Your hybrid medium is messing with you.
For the rest of these plants' lives, you need to feed them. 1/4 of the amount on the charts that came with them.
You can not just drop out a nute without something happening to the plant.

Read these and water this way @25% of the chart numbers with food.
Food mix,
Bloom 50%, Grow big 25%, Bembe 25% and what else do you have?

Hey @Dirtbag , we could use your help on feeding here. Hybrid medium issues.

Use 3 of those and you can have a living soil for organics.
Root Drench, Mircobe Brew, and Bembe. Add to a soil already setup for living and all you have to do is water.

Best temps are 76 during lights on and 60 at lights off. This is the magic zone for growing weed.
