Hey guys,
First off, this is a cross-post because I was not receiving any replies from rollitup forums. The images took a long time to upload so ill just link to the orig thread for those. If I receive some help here I can update future images here in this post instead to track progress.

So I've recently acquired a medical license to grow. I have little experience as does the designated grower. We have a setup that's been constantly adjusted as we dial in the tents.
The plants were fine for the first couple weeks but started to show nutrient burn. We stopped feeding nutrients as the soil seemed to be loaded with them already. Flushed for several weeks and think we have the soil manageable.
The runoff of water tests at ph 6.9 (goes in no higher than 6.8 and we use a meter to test and balance our pH.
The ppm of the soil without anything added has runoff around 1200 ppm. After we leached the soil it brought it down to around 4oo ppm. Still 3 weeks later and the leaves show signs of what we've been treating as nutrient burn.
The tips turn white and the bottom leaves turn yellow and die. Tips are curled and some earlier leaves had dark veins and very pale green leaves.
I'm starting to think the soil had tons of the wrong nutrients and now giving it anything fails.
The next we think to try is lowering the pH a little more around 6 and hope the overall soil environment lowers to reduce possible nutrient lockout.

Should we flush still?
Should we give anything for a deficiency. Or shall we concentrate on pH still?
These were already set back schedule about a month as i dont want to send into flower until we have some healthy looking plants.
TO top things off we just got the LED light installed and setting it up burned a couple of the plants.
We were running a 400W metal hallide in a 4X8 tent. We have two blower fans with a carbon filter exhaust. Temps are within 22-25 degrees Celsius. humidity 50-75%.
We feed about once a week until water flows from the bottom of the grow bags.
I'll post a ton of pics from the early grow to the current stage so you can see the progression.

Would really appreciate any help. These are 10 plants, 5 each of flying bandit and sorry i forget the other strain. I may be able to ask the donor for the strain info again.

Hmm i see a couple issues. First off, thcfarmer.com seems to remove the domain name from the link replacing it with "invalid" so you would manually need to replace that word to "rollitup". but i see their website says "We are currently experiencing issues with viewing and uploading images, our team is working on the issue"
And my forum thread seems to be removed. Shame this is the 2nd site that I've devoted hours of time just to have it not work. I appreciate you checking my thread and advising me. I will try to rectify by manually re-posting all 50 images directly in this thread... when i have time.

I would concentrate on the ph of the soil, not the water or runoff. If ph of the soil is off, amend the soil with some acidic or alkaline amendments scratched into the top of the soil.
Less is more when it comes to nutrients. I started with some pretty good dirt, used no liquid ferts the entire season, only adding worm castings, ground kelp, bonemeal and fish meal to keep the nutrients boosted.
Way less chance of screwing up the fertilizer and a lot cheaper, too.
It seems like you may be approaching soil as you might some of the other cannabis growing mediums.
Best of luck.

Thanks a bunch for the reply. Yeah that sounds like a good plan. Theres already a bunch of bytes bought so bone meal etc we likely won't do. But we will certainly watch the pH closer.

replace "invalid" with "rollitup" and replace "com" with "org"

it seems stripped
