im stumped on whats happening

[iilych]

my friend is growing these plants at his house and im trying to help him without going over there.
today he found that two of his three plants have spots on one leaf and all 3 are having yellowing tips.
from the pictures i cant really tell if its nitrogen deficiency or nutrient burn.
we planted the fully rooted clones on tuesday and watered them with slightly less than quarter strength canna coco a+B
they are still moist so he hasnt watered since then.
ill attach the pics and hopefully you guys can help me get hisissues sorted out

The spots on the leaves look like he watered and left droplets on the leaves, as far the yellowing of the tips if its not overwatered ... I would say nute burn .. you shouldn't have to feed clones for at least 10 days or more ..


happy growin

over fert , heat stress, or ph problem.. Does the soil have nutrient in it ? if so, then you don't need to use nutrients for a few waters, just water and if your using RO water add cal-mag

'my friend' huh? Its only your second post so we can give you that one. LOL

put that cheap nasty moisture meter in the bin and water when they need to be watered, no more nutes for a while.

i know SWIM is entirely stupid, it really is my friend growing these.

we are using coco coir mixed with perlite.
i know its not heat, but the ph is a bit wonky. ill have him start normilizing the pH and just watering with clean water next time and see how it goes

peoples opinion on ph in coco vary. I use soil and found that 6.5 is best for me. Hope you figure it out !

mine look kinda similar.

i fed them guano a week an a half ago, then replaced the soil days ago with mircal gro organic choice.
i might add just a couple pellets to each pot next water...
any advice?

(picks are 4 days ago)
