Plants Dying NEED HELP :((((
Hey guys i need some help
I have 8 bloomers under 2 1k HPS lights.
1 8 in duct fan temperature ranges from 80-90F
Fox Farms ocean forest soil
Fox farms full line of fertz
This is my 4th harvest, 3rd harvest of the same strain, Green Crack.
My first 2 harvests turned out great! My 3rd harvest near the end of the bloom cycle had tons of dying leaves and some of the bud was turning brown and the bud was not dense. I harvested anyway, there was nothing i could do. I did not know what the issue was.
Then i moved my veggers into the bloom room. At this point the plants had some leaves that were dying and crispy but not many, i thought it was because they didnt have enough light in the veg room.
Turns out, my PH tester was almost 1.0 higher than it should have been. I was giving my plants 5.1-5.2 ph water when i thought was giving them 6.1-6.2. AHHHHHHH!!!!!!!!!!
So i figure 3rd harvest was screwed because of the ph.
I immediately got a new ph tester and paper strips for back up.
Then i flushed the plants with sludgehammer and a bunch of 6.3 ph water. that was 4 weeks ago.
Since then i have been giving them about 3/4 the normal fertilizers and 6.2 ph water. At first they looked ok and had good new growth at the tops. but now i have tons of leaves falling off dead and crispy and and the leaves are all curing under and burned at the ends. It does look like there is still new growth and there are buds growing.
At this point, the plants look very sickly. Is there any way they could recover? do you think there are other factors that could be causing this? any suggestions on what i can do to help them? OR is it too late and i just have to scrap them?(((((((
I do want to note that my next set of veggers are doing very well so the heat and ph are fine for them.
I really appreciate any help and suggestions. This is turning out to be quite a shitty month! (guess we all learn the hard way from our mistakes)

Growing in soil the ph changes aren't so important. They did not cause this, the soil kind of makes the water change it's ph to something closer to soil's ph.
If you'r soil ph is okay, ph is not a problem.
Looks like over nuted, or too hot.
Check ph of your soil, tell your temps, and we will for sure save those ladies
Sorry, just read you listed temps. 90 is a bit high, but shouldn't cause problems like this.
IMO only stuff left is ph of soil or nutes.

Whats the cheapest way to test the actual soil ph? do i have to buy an electronic ph probe tester? ive been using a digital ph tester to test the water ph, but have not tested the soil.
i was probably giving them low ph water for about 3 weeks before i figured out the tester was broken. I have been giving them less nutrients then i usually do, but i can cut back more. could over watering cause the tips to curl under and leaves to get crispy and fall off? i may be over watering...
The light cycle is 8pm-8am and the temperature of the room ranges from 80-90 degrees with the lights on. could this be causing it?
To me it looks like they got super burned and are really dry. Even the green leaves dont feel like they have as much moisture as they should. BUT i never let the soil dry completely, i feel like i may be giving them more than they need rather than less so i really dont know...

Yea the HPS lights are causing the horizontal lines, ill take some pics with lights off tonight and post em.
looks like you have over fed them there is major burning to the tips and they maybe locked out. id give them all a good flush with fresh ph ed water only and see if they come back. good luck
Flushing them was the first thing i did, but i keep up with the normal amounts of nutrients ...
how long after a flush them again should i start up the nutrients?
Also, should i flush with sludgehammer or just water?
And is it best to wait till the soil is almost dry before i flush or should i just do it right away?
Also, how long should i wait before i determine if they are coming back or not. obviously the longer the lights are on the more money im losing so its a trade off.

for a decent flush id use about 3 times the pot volume of ph'ed water only and really flush them out, and i would start feeding again when they start regrowing new growth. but i would use alot less than you have been because it clear you have overfed. but also bare in mind im not familiar with your soil does it contain slow release ferts? because flushing may case more nutrient release and more damage in them circumstances. if it is already rich with food and you have been feeding more on top it could be the cause of all your probs.
I dont believe it has slow release fertz:
Ocean Forest® Potting Soil
Good Things From the Earth and Sea
The ultimate potting soil—everything your plants need, in one bag. Ocean Forest® is a powerhouse blend of premium earthworm castings, bat guano, and Pacific Northwest sea-going fish and crab meal. Composted forest humus, sandy loam, and sphagnum peat moss give Ocean Forest® its light, aerated texture. Start with Ocean Forest® and watch your plants come alive!
Garden tip: Perfect for containers and ready to use right out of the bag. Ocean Forest® is pH adjusted at 6.3 to 6.8 to allow for optimum fertilizer uptake. There’s no need for nitrogen fertilizers at first; instead try an organic blend like FoxFarm Big Bloom™ Liquid Plant Food to encourage strong branching and a sturdy, healthy growth habit.
go ahead and flush you should be fine. you should only really start using ferts with a soil like that if or when you notice deficencys in the plant like leaves yellowing towards the bottom of the plant. less is more some times if you do use ferts look for signs of damage and catch them early and simply dont use the amount you have been. the soil will contain almost everything the plant will use over a 2-4 month period i would imagine. again no experience using it but reading what it contains tells me its going to provide everything for at least 2-4 months.
