Brown and Yellow Leaves Tips

Vitorastarted grow question 4 years ago

This brown and yellow colors are appearing on the tips of the lowest level leaves. What could it be? I am watering with 800 ppm ph 6,2 and watering approximately 300 ml/plant/day. She is in a 8 liters bucket.

Hi guys, Thanks for your answers. I just checked the ph and ec with calibrated instruments and it’s actually ph 5,82 and 750 ppm. Any other clues?

Looks like the ph of your nutrient solution is off. Have you tried to calibrate your ph meter?

Overfertilizzazione. Abbassa i ppm a 500. Adesso invece innaffia 2 volte con sola acqua, meglio se osmotica a ph regolato

Thanks! The light distance is around 20 cm. Its close but I don’t have enough space anymore. But this is happening in the lower leaves. The ones closest to the light are not being affected.

It may be potassium deficiency or sunburn. What is the light to plant distance?

Another round of Name That Deficiency 5 weeks into flower and this plant seems to be the problem child but she’s also the one showing the most growth. PH is 6 on her, was originally 6.2 but was having a manganese deficiency so went down to 6.0. Gave 3/4 of recommended nutrients in last feeding. Not sure what to do.
