I have the same problem mate, I thought it was nute burn but after flushing and lowering dose it just got worse, might be a Phosphorus (P) problem, iv given it a high dose of pk today il let u know how it works out

Ya i just lowered my feeding in half was giving 4ml micro, 5ml gro, 1ml bloom with GH flora series nutes in 1 gallon of water this morning i did 2.5ml micro, 2.5 gro, 1.25 bloom in 1 gallon of water and then i split it between my 2 plants so get half gallon each

Those look like PH issues to me gents, ease up on the nutes and get a ph meter to check the run off of the water from the pots to get an idea, or the best option is to get a soil ph pen that you can stick directly into the medium to get accurate readings. Often too much nutes and not ph'd nutrients will result in ph swings which end up with nute lockout

Nice 1 bro il test the ph of my run off tomorrow and let u know thanks for the advice
I don't test runoff, ever. I've found that it is misleading at best. It's much easier and effective to always pH properly before you water, not test it after it's filtered through the medium.
Since you haven't stated what medium you're growing in, nor what you're currently pH-ing to, that information would be prudent to find out if you're off or not.

I always check my ph and ppm before I water bro and if it ever comes off as too high or low I add ph up or down mate so I don’t think that what’s going in is an issue
I'm not saying it is, I was simply asking what your medium is, and what pH you're actually using is all. Just trying to figure out what pH range is appropriate for you to determine whether this may or may not be related to pH.

Oh sorry mate my mistake, ph is around 6 and I’m growing in coco I use the canna coco products and I also add 1ml/L of vitalink calmag
Don't mean to nit pick, but when you say "around 6", what do you mean by "around"? The pH scale works in an exponential order of magnitude manner. A pH of 6 is 10 times more acidic than pH of 7. A pH of 5 is 100 times more acidic than a pH of 7.
As you can see, things change drastically, even by the decimal point.
What range exactly are you keeping the pH in?

I’m using a ph test kit where u have to drop 3 drops of ink into a shot of water, it comes out as yellow every time and never needs adjusting

You should consider getting an electronic pH tester. It's not only easier, it's also more accurate.
Last time i checked the ph run off was 4 but i test the ph with drops it didnt really change colors much but it looked like the run off ph was around 4 with the drops, i lowedered my nutes when watered today everytime when do watering/feeding ph is 6.0, my medium has a ph adjuster im using sunshine #4 growing mix
Ya the one time i checked run off it didnt really work with the drops if it did work it was 4 but it didnt really change colors with the drops before i water my ph is at 6 turns yellow with the drops for 6.0 and im growing in sunshine #4 which has a ph adjuster, nutes i use are flora series
