Yellow brown leaf edges

Hi, I am growing an AUTO in an OUTDOOR pot with 2/3 soil & 1/3 perlite.
I am feeding while watering every three days with nutes and 20% runoff.
Not it is 26-day old and some of its leafs turned yellow on the outline and brown in the tips.
Any idea(s) why?

Looks like nute burn. How heavy and what are u feeding them? Actually a support ticket would help alot.

They dont look big enough for a heavy feeding, thus the nute burnd tips.

I agree. Perhaps the nutrients you’re are feeding along with what was already in soil is a little too much.

Thanks. I have found this site and the information and pictures there are VERY interesting and seem relevant. Should I feed less nutes or water more or both. In the meantime I moved my plants from direct sunlight (it gets very hot here).

I am feeding 1ml Humus + 0.5ml CaMg + 1ml Seeweed fertilizer + 5ml veg fertilizer

Kind of soil are u using? And how old are they? Id probably not feed (nutes, they will need water) again for a couple weeks

They are in 66% soil 34% perlite, 26 day old.

I keep asking the type. As in the brand or maker. Got a pic of the bag?

I am sorry, just plain soil i bought in a greenhouse, nothing brand name. The plant is an Auto.

Just use Ph adjusted water at around 6.5 for now and see how things go. Stop all other fert inputs for now
