Nute burn or hungry?

[Growler]

Hi folks,

I watered this seedling yesterday morning, 1 litre of water with 0.5ml/l A+B Canna coco and 2ml/l rhizo.
Looked fine this morning and then this yellow tip has appeared this evening, I didn't water today as the coco was still feeling damp.
Is this nute burn, or is it asking for food?


Its in coco, 11litre fabric pot. 250w Dual spec, temps 25C RH60%+, fan lightly blowing between it and lamp.

Thanks

just give it the rhizzo fella, till she tad bigger.. yea that's burn, my seedlings were on just the rhizzo for around a week, then i added light feed.

what's your back ground ec n have you ec wand n ph pen?

Agreed looks like burn. Seedlings are very sensitive especially when their not in soil and subjected to systems where everything is very easy to absorb. As stated back off for a bit and watch her grow. Peace

Yeah got a magic wand and ph pen, background ec 0.5 feed at 0.7, so 0.2. Going in at ph 5.7.
I watered with plain ph 5.7 last night.
Thanks for that.
I'll just stick to the rhizo.
Doing a bit of reading and some folk seem to nuke the seedlings from the off, maybe these autos don't need it.

Thanks folks!

I agree what others say above.
Ph 5.8 and only water + 2ml/L rhizo for now.

Probably over watered if you banged a litre through it, I would let it dry out, if you have over watered then you will only make things worse by feeding again!

Thanks for that, So it is possible to over water coco? (oops!)

I stuck a litre in as the pot was really light, twas the 1st real watering after planting (about a week).
