Nutrient burn or defiency

Hi guys need some advise this plant is sweet black angel its currently about 4 weeks into flower and the tips of the leaves are starting to go brown and curl up

Is this i defiency or nute burn?

Its in coco and using the full range of bio bizz ( i know its made for soil) but i have watched the video from bio bizz and it says if you use activera should be fine in coco

I used to use store bought water ( to save the faff) that was a ph of 6 and tested to see if this was correct but the shop have now put the ph upto 6.7 is this plant hungry or needs flushing?

Ive bought some ph up and down going forward but want to know what to do next as really domt want my time and effort going to waste

( the residue on the leaves is from cannacure dried out i use it now and again as a preventative measure)

Thanks in advance

A pic would greatly help.

The forums don't like certain formats. If you have a mode on your camera to compress the image save files to save data it usually changes the extension as well. Make sure your camera is just saving images with default file extensions

Try 2 open the picture in your gallery you already have and edit it. Then save it and try to change what it's saved as. On my phone it's called remastering the picture

Thanks for the advice @ProPheT 216

Plant is a good color. The really bad tips are on older leaves. I think you over fed her in the past and burnt up those tips. Now they are dry and cripsy and very noticeable.

New leaves have some burnt tips and bleaching as well. Back off your feed strength by like a whole ⅓ or at least a ¼

You can add more if she looks like she needs it. Your going to stunt her if you keep overfeeding if she isn't already

Brill thanks for that mate appreciate it no flush then??? just hold back on the nutes a bit going forward

I would do my next feed at half strength instead of flushing. I would do a slurry test before I did anything and make sure my soil ph and ec are in acceptable range still. Overfeeding can throw that off fast.

Brill @ProPheT 216 thanks for the help matr

Tip burn indicates too much nute.

op is growing is coco

your plant looks like it is having issues, you can see it is a brighter green than it should be, you can see the edges are lighter than the centers of your leaves. I am not a coco grower and I would never try biobizz in coco. hopefully a coco organic grower will stop by to help but I see what appears as both burn (tips) and the beginning of deficiency, possibly lockout, maybe cal, maybe mag

are you following the biobizz nute chart for coco? did you buffer your coco?

I did buffer it yeh and im using bio bizz to the chart it does originally say for soil but if you out it in youtube there is a bloke from biobizz that explains it can be used but you have to add activera something to do with microbes you guys will know more??

Im wondering if the problem is to much of one nutrient causing the burn but not enough of another because of the ph level its locking that nutrient out like i say ive been using shop bougjt water that was 6.2 originally and noticed now its changed to 6.7 so for coco that is high no and could be causing the lock out??

This is the chart im going off

this is the video i watched

yes the feeding chart says light mix or coco with the inclusion of acti-vera but most have significantly better results in soil with biobizz. That said you most likely are dealing with lockout due to not ph-ing your water. you are in coco so you have to always ph your water after mixing your nutes

Yep the ph up and down and the pen is arriving tommorow somehow ive thrown my last lot out i will give it a reduced dose with proper ph,d water and see if that fixes it

it will probably take a little time to get back on track but it should help once ph is where it should be
