Grow Mediums Need help with nutes!

[trendkill84]

I am growing a mix bag of mephisto and fast and vast 2 and some mix bag sweet seed.
I am around day 45 on 4 of them and they are looking small and weak with what looks like cal or mag def.
I am growing in coco with and using canna coco a and b. I have some calmag I have been using and I keep my ph at 5.8.
I used to use maxi bloom and a few other nutes and had amazing yields but with this crap I just trying to keep them alive. I use the light dose when I feed and feed twice a day. I am not buying the rest of the over priced crap from canna that is just way too much. What can I use for a booster or other nutes I can add in place of the other canna nutes?

Are you in the U.S.? Or abroad? I ask because some nutrients are U.S. only....etc

Thanks I think I have a cal mag def. I need the rest of the line up just spent too much on new set up and coco a and b. I bought 5ltrs each. I hit it with some cal mag they are looking a bit better. I think my roots are crap too. Will any of this help with buds? I have been buying and trying out shit tons of nutes. I was using the maxi bloom and cal mag which worked wonders

I used to use the canna line and had good results, how strong are your feeds and at what stage did u begin feeding? Usually mistakes made early on will stunt them, they look good now though just lagging behind from being stunted early on.

I am running a and b with cal mag and drip clean with some seaweed here and there at full strength on the light feeding calc setting. I hit them with amino acid treatment from house and garden sometimes too. I just ordered big bud coco going to give that a try.

Water down your nutes to half strength dude never fed an auto on full strength well I did once it caused bad nute burn and stunted them you might need to do a little ph balanced flush when it happened to me all I did was just watered with ph balanced water for a couple of days with a 10% run off just to use all the nutes built up in the coco then fed at half strength or you could flush with 3 times the pot size (1 gallon pot 3 gallons of ph water ph to about 6) then give a very light first feed no more than half strength a+ b good luck dude

I'm not seeing nutrient burn so much as ph issues. I see the mention of seaweed of some sort. Not many seaweed products that don't jack with your ph out there.
