4 week old plant issues :(

hey guys hows it going this is my first attempt at indoor growing all seems to be going ok apart from what i think is a defienency it looks like magnesium def nitrogen def and or over fert to me im not sure which one if you guys can help me woukd be much appreciated the stems also feel very flexible and bend easy the veins of the leaves go yellow then green leaf tips curl down and yellowing starting from the tips

Soil- canna terra professional
Lights. 400 watt metal halide cooltube 30 cm away from top started with 130 watt cfl.
Temps- 23-26degrees celcius
Nutes have given 3 or 4 doses of canna bio vega dont really remember couple feeds of cal-mag and a organic root starter i ph my water to 6.0 but i read somewhere to not even worry about phing organics?. Or canna terra pro

i doubt nute burn because the new growth is untouched, could be nitrogen or magnesium but how can you know if you don't pH anything? you should probably at least test it even if you're not adjusting it just so you know whats going on there. I'm new to growing so I can't really help much I just wanted to see what was up but i feel like knowing the ph is pretty important so you know if your locking things out or not but yeah heres a ph chart incase you want one, probably going to be a magnesium lockout if anything so I dunno what you need for organic Mg for your plants but yeah id get some of that. good luck!

Haha no i do ph my water to 6.0 i said i read somewhere they said dont even worry about it and i read that today haha.

oh lol my bad i was thinking damn the amount of problems I've had with ph, if i didn't even look into it Id be fuuuuuuuuuuuucked

I'm just curious, is this 4 weeks from seed or fveg? Or was it a clone

she looks hungry mate to me. Shes devouring her own first fan leaves. feed her up a bit more but don't overwater, get plenty of run off drainage water aswell.
too many people feed back in what the plant shits out. lol by letting them sit in their own waste, eventually they will suck it up, not good, all that excess salt etc..
can lead to 'lockout' where the plant wont be able to feed, ie.. classic plant constipation.

3-4 weeks from seed mate

Stick with it mate, you've got a nice structure and it looks healthy besides, A&O's making sense.

Your plant is going to heaven.

Yeah should i? Since i flushed her should i just feed with nutes now? Or let her to dry out first. I nearly threw her haha. Shes not looking as good as the others instead of throwing her i threw my ph pen haha

Yeah defanitly looks that way which is why i said should i just scrap her haha i have 5 others

Im just so confused on what to do

Iv'e not used canna (other than their nutes for hydro) but i'm surprised the soil needs amending., especially just 4 weeks in, maybe the flush/watering has done it. Unless you have a soil bug try the small doses. When I have dramas that I cant fix I just pot up, letting most of the old soil fall away. Leaf wize your new growth is healthy, silly tossing it, what happens to the next time? Keep trying and learning from it bro 3/4 strength nutes to the area around the stem, let it dry right out then give it a good drink (as I say you shouldn't really need to be adding nutes I wouldn't have thought) are they salts the canna, organic nutes (ie for hydro)? May do better with a weak NPK? I use Seasol/Powerfeed for my soil grow (coco, peat soil mix) (when necessary) Hope this Helps

Okies i am gonna do what you say. Shes looking so droopy now. I used power feeder and seasol outdoors they where great got a bud the size of a 2l coke bottle from that stuff and people say organics dont do well thats just cos they cant grow it well haha. I

This stuff is insane lol

I may just move to coco seems easier keep ya ph at 5.8 and you barely over water and feed atleaste once a day or whatever you want really seems so much easier i thought the canna terra pro would be ok yeah the plants grow insane in it but its just so hard to determine whats hapoening with if

This is how they are doing now much better i got a new ph pen a good one got the roots sorted to 5.9,
