Yellowing/brown tips of top leaves. Heat-burn, light-burn or both?
steveaustinstarted grow question 10 months ago
Top leaf tips turned yellowish, brown with curling. I'm leaning towards light burn as the cause, but noticed it started occurring during the recent hot weather. I've raised the lights, but am wondering if this could actually be related to the heat.

Looks like nutrient burn from prolonged high levels of nutrients. Some phenotypes are more sensitive than others. They usually start with the tips turning a whitish color before turning brown. I usually back off nutrients if they all start to pale on the leaf tips. I would use less nutrients in your mix.

Hey, tats typical of too much PK and not enough of other nutes, with N & micro nutrients
What you're actually adds to tat brands. Its actually for an extra pk booster for flowering. Shouldn't be on tat by itself.
I do see your leafs clawing also. So, she's coming off the back off too much N..how many times u feeding..with soil once a wk? Wit tat ml/l you shouldn't been seen nute burn unless u giving on reg basis

What is that?Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6
Increased light intensity to PPFD 600.
This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick.
If it's a light burn, why not on upper leaves?

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?
