Yellowing Leaves

[chiselwizard]

Hi Folks,

Having problems uploading photos - let's see if this works.

Growing auto in soil under 250W HPS. 3 weeks into flowering. Temp 22-30C, Humidity ~50%. Using Shogun Samurai nutes at 3ml/L (recommended 2-4 ml/L). I'm waiting until the pot is light before I water and aim for 20% runoff. All good stuff that I learned here but in the past couple of days some leaves are turning yellow.

Any comments/advice gratefully received. My first grow and its been going well up to now.

Hi mate, 22degs lights off and 30 on am i right? Also i'd get a little bit of epsom salts in warm water next time you water buddy.

Sorry, I meant that the temp fluctuates between 22-30C, although I try to keep it at 25C. Lights are on 24/7. I'm about to hotfoot it down to Boots to get some Epsom salts.

Un perfumed and don't add to your soil mate

Did a few searches and it seems like a teaspoon in my next feed is the correct dosage?
I know I'm being thick but what do you mean by not adding to the soil?

Wow I have no idea of what can cause it .... SyRaX can you explain me a little more of what is happening with that schedule lights vs temperature???
I would say that that's not a nutritional deficiency because of how the lateral branches look like ... anyway epson salts will help out the plant .....
Looking forward to learn : )

Hi mate put half a table spoon of the crystals in a jug
Add a litre of boiling water to dissolve the crystals
Wait to cool down or add cold water and put in a spray bottle
Spray the leaves. And the underside aswell
This way works faster than adding to your soil which can cause its own problems
Raise your lights until the leaves have dried
If your in flower you can still spray just not the buds
All the best mate
