Yellow/Brown spots on the leaves

[wanna be dagga kop]

Hi, 

I'd appreciate some help with diagnosing this issue I have with my leaves, there is yellow/brown spots on the leaves and I am not sure as to what is the cause. Any help would be much appreciated.

Yo. I had the same "issue" a while back. It was diagnosed as burn from nutes wetting the leaves and then came in contact with the sun. Could also be hot soil. Mine recovered quite quickly. You should be fine

okay thanks man, it's most probably from watering as I feed only once a week. I highly appreciate the help

What medium you using

How big is the pot

What do you feed and how much

How old is the plant and how long in the medium?

Some of those marks may be from spilled nutes, but your leaves are very dark and look 'hard' and some of those whitish interveinal spots look like Ca def.

Aweh, 

So I'm using freedom farms green bag of soil and they have been in the pots now for 6 weeks. Pot size is 15l and I'm only using 0.5ml bloom per 2lt. It's autos so I'm being light on the nutes.

How long into flower? Cant see from the pics.

A maintenance dose of calmag should sort the Ca.

Raise Bloom to 2ml per liter. Is that all you feed?

It's first week of flower, 2ml is too much for autos, I'd rather under feed and build up than burn the plant.

2ml bloom is the smallest dosage i give. I think those brown spots are potassium deficiancy. Can you make a picture of the full size plant, please. Need a better overview. What else you give them? Only bloom?

I grew over 300 autos so far... i know autos a little bit.

Here's a pic of the plant that the leaves came from

Autos are fast, they need material to build ^^ When you see the tips of the leaves going yellow.. give twice water only. Then back to feeding. 

Increase the Top Max by 1ml per liter, depending how the buds get bigger, 4ml max last 1/2 weeks, sometimes hard to guess it right. You should end for the last 2 weeks before the flush week on 4ml bloom per liter too, stick to the 1ml grow, no need for more on that side. If you don't feel happy, 3ml bloom also does the trick. But I used 4ml Bloom on Autos a lot and never really had a issue. I really recommend Bio Heaven for the BioBizz range.. is what makes this fertilizer set special. Top Max is also very much recommended.. the rest is just the usual NPK.
