Technical Issue Hulkberry Auto - seedling stage, strange leaves, please help.

[x00m]

Hello,

can you please help me identify the issues with this, i had a look at the sticky thread, it seems like its phosphorus deficiency, but i could be wrong... i mistakenly fed the plant for a week with a ppm of 1332. and when i noticed, i quickly changed the water flushed it with ph balanced water, then changed the water again with correct PPM levels of around 400.

i am using Canna Coco nutes, for the seedling i used Coco A/B 1.2ml each and 8ml of Rhizotonic in a 2.5L aeroponic propagator.

Many thanks,

Try bumping the ppm up they look light in color and I think 400 is little low for that age take them up to 450-500ppm

the colour got like this when i left the plant in a 1330ppm solution. hence why i lowered it down. its actually at 435ppm to be exact, i just said 400 to round it down.

do you not think it will recover at 435ppm?

It might recover but it might have deficiencies typically anything under 550 I’ll see deficiencies. FWIW I’ve heard of guy running that high of ppm but I don’t I don’t go over 700-800ppm and start hitting them with full strength by day 14 I start at 300 ppm then start raising the ppm 100ppm each fertigation after the first true leaves are 1”

so update from the first post, which was 4 days ago... i have adjusted the ppm as suggested.. and the plants still seem like they arent growing.... are these dead?

any suggestions would be immensely helpful

thanks,

Could still be recovering from transplant auto can be sensitive to transplanting is that coco they are in? Could be underwatered if so cause it looks like chunky stuff that doesn’t hold alot of moisture

yeah its coco, im hand feeding it just now, but ive got a bottom feed system ready to go. just waiting for the roots to establish before wasting so much nute flooding the cocos.. or would it be worth just turning the whole thing on and letting it do its thing?

 

[Lil Dab]

No I wouldn’t turn on bottom feeding system till plants are well established good sign of that is about when the leaves have reached the outside of the pot. I’d keep feeding by hand for a bit longer and maybe do it more often but I’m not sure how much and how often you fertigating now. Are you watering till runoff when you do feed?

im not feeding until run off. ive only just fed once since transplanting. i feed once every 3 days. feeding until run off would mean saturating the entire 30L pot with water does it not?

should i increase my feeding frequency to maybe once a day? but the substrate stays wet for 3 days or so, which is why i thought maybe ill feed it when it dries up again.

Yes water/feed the entire pot to 10-20% runnoff when ever you do water. When plants are young I start with once a week to runnoff second week is 3-4 days apart from feeding by week 3 and 4 I am feeding once a day then in flower it’s multiple times a day coco for cannabis is a really good resource for this.

You do not need to fertigate coco every day when the plants are small but you must water the entire pot to 20% run-off any day that you do fertigate. It is all about keeping the cation exchange in the coco in equilibrium. If you only partially fertigate salt build up begins immediately. You almost cannot over water coco
