Brown and Yellow Leaves Tips

Vitorastarted grow question 6y 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?

Overfertilization. Lower the ppm to 500. Now instead, water 2 times with just water, preferably osmotic with adjusted pH.

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?

Potassium deficiency?Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Found six different spots of small bud rot on amnesia and removed it all. Should I start flushing now and chop in the next few days? Or push it longer. Expecting rain all week so might be time to give up. Also, how much longer should she have gone?
