hey guys, my 2nd time growing myself as I got fed up of paying for it,have got 4 autos 2 girl scouts and 2 gorilla autos in a 4x4 tent,with 900 w led s, the leds have both bloom and veg swithch on now and have been for a week,they are 5 weeks in now and I am starting to get worries about yelloing of leaf margines and tips of old a new groth and not sure whats going on, my feed was at 0.8 ec and have slowly rose that to 1.2 ec ove last 2 weeks or so,but my runoff is always 0.3 ec lower than what im putting in don't know it this tells anyone anything any advice would be ace and very much appreciated as don't want to take messure only to make things worse, thanks again guys ow and are using canna nutes full range minus call mag as live in an area with tap water at 0.42 ec to start.
Might be hungry then mate, if the EC is consistently coming out lower, up the feed a little more. Five weeks through and flowers are forming now, or five weeks into flower? A little spray for some epsom salts will fix it i think, but that will depending on if there are flowers or not.
Lets see some pics as where the plant is in its life cycle will help get a diagnosis right

Thankyou for response will put pic s up in an hour with last night's reading aswell, I was leaning towards under fed but just not got the experience yet to know
these pics taken over last few days lights on pics a mainly yesterday day before lights off pic have just taken thanks again in advance for any help or advice,reading still low in runoff,1.2-1.3 in getting 0.925-0.95 out ec atm,still seems to be growing atm and am just entering 6th week since seed and is showing signs of flowering over the last week
These were taken today during water same results as I have been getting uped nutes to 1.4 now probably up it .01 tommoz again and order Epsom salts I think how much should I use of the salts dont want to cause another problem
thanks again for any info of ya wanna know anything else will be happty to respond
Hmm, those look pretty decent to me... what is your pH coming in at? Could be a bit off and starting to lock out some nutrients..? They don't look bad at all to me from those pics tho.
And welcome!
Thanks, oh my water at 5.7-5.8, the run off comes out at 7 but have read not to worry much about the runoff ph so haven't been just on whats going in :),maybe just over thinking it just dont like the yellow lol
Look like it could be a cal.mag issue, a spray of epsom salts will do them good i think. But like TG says mate, they look good. Don't be too quick to try and treat everything, especially minor changes, it could be the plant just adjusting to a new feed or something.
As flowering begins, their need for nutrients will change, a little bit of an epsom salts spray just as flower starts always does my plants well. Try that and they should pick up I think

Wicked thankyou very much for your input puts my mind at test abit more and I know a happy grower tends to get better results :),will order some epsom salts on amazon today and give a spray when lights go off tommoz should I keep my feed steady at 1.4 ec for now you think then see how they go type of thing
Depends what's in it mate. 1.4 is a bit high I think, but it depends on what nuits you're using.
You on bloom nuits now? If flowers are forming, you want to reduce the amount of nitrogen the plants are getting, and increase the PK.
What exactley are you putting into the water mate? tell me:
Your background EC ( EC of plain tap water)
EC after adding your food
How many ML per litre of what brand, and type of nutrients your feeding Then we can get her proper diet sorted for the next few weeks

- Hey am useing canna coco pro,with canna nutes a and b 25 ml per 15 leters,was useing rizo but not anymore,canazyme at 25 ml per 15 leters,and am useing boost but only at 7 ml for the 15bleters, background ed before nutes is 0.42 so slightly hard water area I think,ec reads at 1.4 ec or just above when I've mixed it all in hope this helps,was thinking of adding abit of pk this week to feed but was not sure when to start it,that's also canna brand, wanted to keep everything the same brand as didnt want to complicate things for myself early on thanks for ya time you guys are awesome:)
Same nuits as i use mate.
The 1.4 EC should be ok, but, reduce the A n B, and cannazyme, get some PK 13/14 and make the Ec to 1.4 again.
1ml per litre of a n b so 15ml per 15l, and do the same with the cannazyme, then bring the ec up to 1.4 again with the PK, itll be maybe 1.5 ml per litre, but go slowly to be sure.
This will reduce the nitrogen, bit give the plant some extra pk now she is forming flowers.
Are you watering every day?

Wicked have ordered epsome salts so they will be here tommoz just in case anyway as they are cheap enough and I'm sure will come in handy, happy day good to get some advice from someone useing the same stuff,I am watering once a day at the moment, am keeping the boost low because of them being autos but will start adding some pk in from tommorrows water starting low and building up abit I think then,some places i had read only to use pk the week before your final flush but I'm learning it depends on so many different variable on when to add things and at what levels it's all so educational i love it
i had read only to use pk the week before your final flush
You will read some crazy things mate 😉 Experience is the best teacher.

Just update have sprayed epsom salts yesterday, ex is still constantly low in the run off compared to what's going in and leaves at bottom of plants one or 2 are dieing not sure if it's normal but I'm sure it is just me being a non and not knowing yet.feed ec 1.3-1.35 started adding pk at 10 ml per 15 leters to begin plan on upping slightly as flowering continues,tips still look abit yellow on 2 of the plants dont seem as bad on the other 2 based on your guys advice so thanks again
Looking good man. Things fix up fast in coco, a flush and a refeed can fix a plant of most issues As they head into flower, a little spray of epsom salts always seems to do then well
Keep us informed of the progress mate

Hello again it's been 4 5 days and the growth has been really good ,I am still abit worried about the leaves at the bottom is it normal? They all seem to be doing the same atm,have upped the pk a little bit more and am enjoying watching then go go,still feeding e c 1.3-1.4 atm hope everyone good
She hasnt quite finished that transition yet, so she still needs a lot of nitrogen for the stretch. Keep on the grow food for just a few more feed before upping the PK any more
The bottom leaves won't be getting as much light as well. So they may turn yellow and fall off, all in all, looking great Keep up the good work

Cheers for response man and will do,will keep a and b up around the 20 ml mark for the 15 leters then for abit longer cheers,
You only need the PK when in actual flower and even then not massive amounts
So should I stop pk all together then for now ? Have only been useing it in very small quantities at 10 ml per 15 leters and was gunna build it up as flower progressed so to speak could this do harm, the leaves at the bottom are not getting loads of light but there dose seem to be a few dieing but everything upwards look okay abit of tip burn but not bad at all, have uped my a and b back up abit and dropped the pk back down for today's water thanks for your input ec of feeding back to 1.4 from 1 3 over the last week
