Help! 4x8 LED Grow (Day 34 Of Flower)

[Zan3747]

Hey guys i'll keep it short and 2 the point. 2nd grow in a 4x8 gorilla grow tent. Using organic nutes ( as seen in pic ) w/ 2 330w Advance LED full spectrum ( turned purple lights off for photos )

Using well water that comes out @ about 6.5-6.8 PH but is fairly heavy w/ minerals ( suspect this may be an issue )

3 skunk #1 / White widow plants and 3 ChocoLopez and 1 "Akorn" All free seeds i received from my previous order.

SYMPTOMS : Light greenish color accompanied by hooking and a burned look. Purpling on tops of most fan stems. Other plant seems to have heavy green w/ a little cupping downwards.

Have seen these issues worsen over the course of the grow and have not been able to fully reverse them, have tried epson salt foliar feedings as suggested on another forum w/ little success. I backed off nutrients completely for almost the entire beginning of flowering assuming that may have been the issue.

MY GUESS : Hard well water creating serious build up causing nute lockout? Not a clue as to how to fix this, sledgehammer flush?

Would appreciate any help, things have gotten worse in the past few days. Tyvm

Here are a couple things that might help.

Have you checked the ph of your runoff? Also, are you supplementing with Cal/Mag?

I know for a fact that i have a heavy phosphorus deficiency and possibly even nitrogen + zinc... i started up w/ nutes again after laying off for a few weeks thinking they may have been the problem but neither has done any justice.

Started thinking there was just a lockout and they weren't getting anything but have not found a way to remedy that. I have been working with well water and suspect a salt or mineral buildup in the soil. Do you recommend using a product like sledgehammer? I didnt think it would be necessary using organic nutes but this is my first grow using well water.

Was about to go buy a shit ton of distilled water and flush using that along with a heavy cal mag feeding but not sure if that will remedy the build up if that is in fact the issue.

extremely frustrating and across all 3 major marijuana forums nobody seems to have a real answer

what nutes are you using?

what nutes are you using?

General Organics line at about 1/4 to 1/2 at most.

Purchased some sledgehammer today. Thinking about doing a distilled water flush tonight. Cant get my hands on an RO system for another few weeks

I think your hunch is right do as suggested test your well water with a TDS meter for PPM's then it leaves no doubt,I would flush with distilled water and use it only, certainly until you can test your well water .
