Hi everyone, hope im posting in the right place. Can anyone help me with identifying whats wrong with this plant? Lights: CFL's and only about 160w total spread over 5 bulbs for 1 plant(3 x 45w(2700k) 2 x 23w(6500k)). Recently added home-made Cree LED(2700k) running at 50w on a LED driver 16hr on 8hr off Growing media: Soil; Canna plus Stage of growth: Veg Nutrients: Biobizz veg(currently using) and bloom(obviously not using till flower, although i put a spot in once or twice beacause it had other elements the veg didnt have for e.g boron, magnesium and iron(I think it was them anyway)This was in the hope it would correct a def) Ive used epsom salts too to see if the problem was magnesium or sulfur(ive read in a guide that epsom salts helps these) I cant really afford to spend loads on bottles of stuff for it so ive tried some organic kelp that we use in our smoothies as I read seaweed is the main extract in a lot of cannabis bottled stuff to help with diseases. I understand Ive probably gone the wrong way about it to find out whats wrong hitting it with all this stuff, i have to admit I pretty much was panicking without thinking to deeply and sort of hoping it would fix itself as i have a friend that uses almost identical inventory and his are absolutely fine. I didnt at first but after a while i started when my issues began with checks to the ph of the water fed to them( fluctuates out the tap at 7.2-8, nutrients lower it by 0.6ish usually which is enough when its out the tap at 7.2-7.4ish but if the water comes out the tap at 8 ill drop a few drops of lemon juice in there too, to bring it down a little bit, i know some people say no to that but ive seen at the same time that others swear it works fine instead of ph down. Run off ph is usually between 6.6-7 btw.) Theres pc fans blowing over the very top of the canopy. canopy temps when lights on are between 23c and 28c. when lights off they are between 18c and 21c although recently they have been going down to 16c but never below and i believe that to be the threshold sort of for the lower temp range I have a carbon filter on a 4 inch fan(exhaust) and a couple of little pc fans as an intake(read that bigger exhaust and smaller intake creates negative pressure so if there are any air leaks it wont let the smell escape still) ok now the embarrasing bit, its been 'alive'(barely lol) for like 5 months ive low stress trained it quite a bit but its still only like the size of an asda carrier bag when full, obviously whatever my problem is most definitely stunts growth. (Just to be clear btw, I have read for hours and hours and days and days but no matter how much i try to compare my problems with other peoples and like guides and stuff i always come to the conclusion that mine looks like it but not quite bang on. For me its been like looking up whats wrong with yourself on the internet and then finding out you have a hundred different things wrong!!! Watering every 4-7 days depending on the weight of the pot. SYMPTOMS From what I can see... Used to have loads of big fan leaves, now it hasnt, most of the new growth is small leaves whole plants gone a weird light green Slight burning on 40%-60% of the plants leaf tips(im using less nutrients than biobizz states) Some of the yellow leaves have a pink/purple colouring to them Some leaves are yellowing like what looks to me like a nitrogen deff(slowly going yellow evenly no necrotic spots or anything they just look healthy apart from going yellow) Brown patches on alot of the yellow leaves but also some of the more greener ones Some of the leaves have pink/purple veins regardless of whether they are yellow or green still Any help would be greatly appreciated and if ive broke any rules im unaware of please let me know and ill correct them as i dont want to be a pain to the site!
