Outdoor Auto 4 weeks, Yellowing spots

[James dBong]

So, the temperature is bad for 2 days, the plant showed some yellow spots on the leaves, I started feed on 3 week whit veg nutes, 2 times that week and other nutrient for the coco soil, know is current age is 4 weeks and 2 days. Will put some pic's from the other day.

Btw, the new leaves that are bigger, show yellow tips

It looks like micronutrient issue to me. Whwn you grow in inert medium such as coco it's entirely possible. I'd bet it's a Ca/Mg issue, so coul be fixed with CalMag or Epsom Salts, also limestone flour.

Thx! Yes im going for epsom salts, can you recomend how much per liter?

 

[Cruizer]

You could do 1tsp, I would put the epsom salt in warm water to dissolve, then add that to the liter of water.

Okk 1 tea spoon right, for every 3 watering? is coco soil so she needs lot of ca and mag. When should i stop giving?

 

[Cruizer]

Not sure with coco but i use about every 3rd watering in my Peat base mix. I also foliar spray under the leaves with a mist, helps too. Probably will need to keep using it through the grow. Look for the signs. They'll tell you.
