Hole in leaf

[5ern]

I checked my plants today. 5.9 PH and EC is 0.8. The plants are almost 3 weeks old from seed. Its only one leaf with hole in it and the same leaf was brown on the tip. When I touched the tip it was crisp and fell right off.

What is your background EC?

0.2 ec. The other plants are good.

Your feed is too high for this stage.

Try halving your nutes.

U sure? I have fed them this 6-7 days and they was all good until now. I do got ventilation direct from outside to inside if that matter? Lowest temp in tent is 18 and highest is 25 celsius. Watertemp i stable at 18.

If the tips are brown and brittle then yeah.

I have a girl day 17 on EC 0.3 and a nice shade of green.

0.6EC for 3 week olds is too high IMO.

Every plant is different some can take more, some less.
