Right guys my girl is 28 days into 12/12 under 600w hps in biobizz all mix soil. being currently fed 2ml bio grow and 5 ml bio bloom per 2 litre give 5 ml of grow last feed to help with fast yellowing problem. I from what I can find it seems to magnesium but I gave a high dose of epsom salts over a week ago so I'm stumped.the problem is only on top leaves no lower leaves showing this sign also got yellow tips on my sugar leaves, and a brown spot on a sugar leaf and again this is only happening to top part of the plant no lower bud sites are affected so here's some pictures getting really worried now 😕
I think you way worrying too much, you have slight nute burn there showing on tips but not even in every pic, still looks healthy to me you getting well into flowering so you know what happens to leaves anyway, the fact you have a bit of burn may have caused nute uptake issues but look how good you're doing compared to some of the disasters on here
35ish days of flower no problems with burn at all, leaves yellowing some rusting being feed max everything still happening

Are you following the instructions on the biobizz website? Although I'm using biobizz as well I'm not going to try and advise you because I'm not convinced European and American biobizz is the same. I found out 3 weeks into flowering that you're not supposed to pH the water which means I was probably making it harder for my plants to absorb nutrients. Check the website in your area for feeding schedule and pH recommendations. Also on my local site there is no mention of giving plants Epsom salts so check that info is still up to date. I'm in week 4 of flowering as well there's a link to my grow below.
None of thats b Nute burn but wpuld.be easier to tell if itnwas done under white light rather than hps. Looks more like a def and the white tips would suggest under feeding and not nute burn and its not burnt looking whats the max does you can give in bloom.and worknya way up to it auto help page if you need help with autoflowers http://forum.grasscity.com/index.php?/topic/1294434-Need-help-with-autos?-Welcome new vote page sept please vote http://www.dutch-passion.nl/en/photovote/2014-09-03-autoultimate%C2%AE-loki_1752/
max dose is 5 ml per litre mate i thought giving high doses early would cause problems what do you recommend to up the feed ?

Thats a good method if your in soil. Different strains require diff levels. Why drink when you can smoke?
You look fine for mid flower, just starting a fade, nothing you can fix before they are done. Sent from my iPhone using Grasscity Forum
Does it matter if the sugar leaves die then ? As long as there's plenty of fan leaves would losing them matter and can I cut dead ones off or leave then
usually your sugar leave don't die as bad as your fan leaves. It is very normal for all or almost all fan leaves to die, from your pic, your sugar leaves look fine. however if you are still feeding nitrogen, then stop now.
From experience and a bit of reading a nitrogen supplement first half of flowering maintains the health of the plant longer, dying sugar leaves carry more moisture and just where you can't afford to have any excess moisture, that's just my opinion though and happy to be schooled
I am feeding biobizz grow at 1 ml per litre which it says to do on their feeding chart all the way through. there's also nitrogen in my bio bloom feed, just another question for you mate looking this morning some sugar leaves on a branch or 2 started going yellow like i said now they got brown patches forming on the tips strange thing is the yellow tips is only on the very top buds I can get a snap of them if you like
