How old are the plants in the pictures? Can you post the recommended dosage of all your nutes and additives please.

Plant is day 50 in the pics

Recommend usage of:- Sensi Bloom A+B is 4ml per L, Shogun Calmag is 1ml per L, Carboload is 2ml per L.

I dialled back the amount of Sensi Bloom she was getting as leaf tips were showing sings of nute burn.

:smoking:Mango, what's up? ..... mate, did she dry out during this period? that will muck up pH and availability temporarily, as well as shock /damage the roots,... in any case, she looks to be eating the fans aggressively, P and N from closer fans, not below so much,... did the tip burn appear at this time? Not much to do beside keep her fed best you can, to stave off the worst of the fan tapping until she's ready for pre-harvest cleanse (if you do that),...

Some of the older bottom leaves will yellow and this is nothing to worry about.The very yellow leaves will not come back so you should remove them.I think you shoud raise your bloom nutes to at least 10ml per gal.except sensi a witch is all nitrogen and not really a flower nute.Also raise your cal/mag to 10 ml per gal now that she is in full flower and your using LED lights.Unless these nutes are PH perfect make sure you ph your water to 6,5 or as close as you can get.This is what i would do if I had this problem but it is just a recommendation and you may choose what ever you feel is right for you.

@Waira Yeah she was very dry man. The tip burn was already present before the leaf problems appeared. I usually flush with just tap water 10 days before harvest.

@namvet25 Thanks for the input bro, I will increase the amounts I am feeding her and see how she gets on.

Let me just express how awesome this site is. I have never seen a better staffed and attentive help crew. This infirmary, and AFN in general is godsend for us home growers. I don't take it for granted, there is not much like this out there, if anything. Imagine getting free and timely expert technical advice for growing tomatoes for example....

 

[Mangos]

@green genes absolutely brother. I have encountered problems with a few plants and help has always been on hand in a timely manner. As a new grower I appreciate the patience shown to me also!

Keep up the good work guys

...--Thank you me chums! We appreciate that! ....I got plenty of help (Nammy too, even if he denies-! ) from staff and members too, when I started out, and no crap given about some sorry-chucky results I've had! ... just payin' it forward,...then you get gaffed into the machine and put to work here! ... Nammy is actually a better auto grower than I am! Diagnostics is a whole different gig, trust me! ....The best growers rarely show up here, avoiding trouble and dealing with it are different skills-

>> Mango, I figure you can shave a few days off that cleansing period (meaning no nutes, just water; not flushed) since you haven't been hammering her with high nute doses,... for convention's sake, here "flushing" is literally just that, pouring volumes of water through your medium to purge excess salts and other build-up's,....
