whats wrong

[liat]

leaves are getting yellow and after brown
is this over nutrients or under?

My mind is saying several things what’s wrong.
but with literally no info about your setup it’s hard to know..

PH levels ?
soil - which kind ? Do you have perlite or leca mixed in the soil?
how big is the pot ?
nutrients used ? When and how much ?
supplements - any cal mag used for example?

[liat]

ph 6.5
light mix with perlite
11 litre pot size
sensi nutrient one time a week
i use the dosage for 1 litre in 1 and half litre
outside grow very hot now
cal mag??????

I don't see much perlite but you say it's there. Does that soil mix have nute suppliments in it ? Looks lacking in N to me.

so its better to flush?

[SoOrbudgal]

Like the Captain said are you using any calcium/magnesium ? They need minerals and a light airy soil mix with LOTS of drainage perlite helps prevent nute lockout also dense soil no air locks in. But i think your soil is the issue and if it's so hot how would you feel sitting in it for over 8hrs a day? Plants are like people almost the same needs in my book.

[liat]

yes i use Hesi nutrients

[liat]

and when i check with finger a day after i water them the soil is cold condition

Look under the leaves with a strong magnifying glass or hand lens. It looks like you may have spider mites. Treat with neem oil and pyrethrin. Use full strength nutrients and also use the Cal Mag or some Epsom salts (1 teaspoon per gallon of water)
