I'm also give recommended amour of bud candy and I'm about to add big buds from advance nutes. No root rot , and temps are fine. I have two of the deep purple and the other one looks completely healthy please can some one help me out. And please tell me how to post pictures. I'll post them in my photos in the mean time.
Thanks
 
I am not an expert and have had the same problem as you describe. I tried a lot of things and still had the results you have. I believe it may be a nut problem in your case. The reason I suggest this is the large amount of different nuts you are using. Most people have at some point during flowering add to much in the hope of a better crop. In most cases there is no need to use much more than your primary nuts. I use my main nuts according to directions not adding more and only in later flower stage add a P boost and molasses as a harding agent.

One more thing that could change things up is LED lighting. If you have changed to LEDs you may have them to close to your plants and are giving too much light. I have had it happen to me so just passing it on. I hope this helps you.

Personally I would dump the reservoir and add your nuts but at 1/2 the normal level and keep away from any other additives, check your PH really important regardless of what the directions say not all PH balanced nutes are in fact able to correct PH. I find that a lot of problems can be traced to two things, over fertilization and improper PH. The other problem may be salt build up which is caused by hard water to much nutrients which causes a build up. So before adding anything use a lot of either plan water or distilled water to rinse off the extra salts from your roots. I do a flush anytime I have a problem just to make sure it isn't something as easy to fix as a salt build up.
 
Just a quick note: If you do as I have mentioned flush and only use 1/2 of your reg nuts and adjust your PH I suggest doing the same to all of your plants if they are the same type. What you see may be only the first one to show a problem. If you have a TDS pen or other device check the PPM on the water before flushing to make sure you are within the correct range usually less than 2000 PPM absolute max. Many plants need a lot less, when to high a nut lockout can occur.

Good luck and please let us know how they do in about a week.

Also i dont know if i should remive some fan leaves like
u reccimended

I got this problem now but my plant is only 3 weeks old. Did you figure out what was wrong and did the problem correct it self ?
 
Just to confirm - this is nitrogen toxicity right? the plant on the far left. the other 2 are almost ready for harvest, showing signs of amber tricombs.

Ive flushed it once already, with about 3 times the volume of the pot, PH 6.3/6.5 water

I plan on giving bloom nutrients again next time, will it survive? It happened in like 1/2 weeks time. Should i give it some epsom salt or cal-mag as well? or quit that too? any other tips would be helpful. Thanks all for your time
