Need help! Patchy yellow marks & spots on leaves, lower growth a pale green

[Jay Bird]

Hi, this is more first grow - plant is 22 days old it’s a northern lights by victory seeds autoflower

5 gal fabric pot
300 watt cfl - waiting for new mars hydro light
23 days old
Nutes - old timer grow at 1 ml per litre
First feed was today - but feel now I should of fed her on last watering

Just need some help if this plant is having problems and what I can do to make this a successful grow

We are having a heat wave in the UK and temps are reach 32 degrees (that’s hot for UK lol)

Appreciate any input or what I can do like I said to make this successful

Plant has obviously need LST going to spread the branches out a little more later

 

[Buds Buddy]

Plants look fine. Any chance you got water or nutes on the leaves while feeding ? I only see a couple of spots on the leaves that looks like they could have been caused by water droplets on the leaves.

 

[Jay Bird]

No dude that’s why I’m a bit confused I’m really careful - I have sprayed them with something called plant magic evo but only straight at lights off - I feel like I should of fed them probably on last water - thanks for your input man

 

[Jay Bird]

I don’t know if it’s heat stress because supposingly this plant likes lower temps and she’s had high heat problems from the beginning - that’s why I can’t wait for my mars hydro QB

Welcome. I don't see anything to be overly concerned with. Your new leaves look good.

 

[Jay Bird]

Thanks dude, I feel like it’s okay for a first grow - found some Epsom salts in my partners bathroom cupboard so going to do a light Spray as I’ve been reading around at some journals who have been using the same Nutes as me and have been getting mag def

 

[Jay Bird]

@Emilya hey ou helped me massively with watering and the seedling stage any input would be very appreciated

 

[Lymphaticus]

I had a plant once that the leaf points kept setting on the leaves below causing little discolored dots.

[Jay Bird]

Yeah that looks similar to mine but it was happening before the leafs started to touch - I personally think and this is my first grow lol so could be wrong - that I fed Nutes too late and that I have a sligh mag def - thanks dude

 

[Jay Bird]

Also since I have given Nutes this morning like five hours ago she already seems better off - first grow so not a pro but love learning about these little problems

The yellowing from the bottom appears to indicate that there is a slight need for more food. More light means a more hungry plant. The spots look the start of a deficiency of some kind, but it is too early to tell if this is magnesium or more effects from a lack of K and N. More time should point us to the problem.

Thanks so much Emilya

Hi JayJay!

I'm no expert grower but I agree with Emilya. This looks similar to how my Magnesium deficiency showed in my current grow. I agree that you should have started your nutes earlier. I lost a number of plants from my kast grow from not asking for help soon enough.

Which brings me to my primary point....WELCOME to 420magazine!!!

Thanks for everyone’s help I really appreciate it , and cheers @Magnus8

I like to be patient I think I was a little too patient with the Nutes but think I have caught it just in time as 8 hours later she’s perkier thenever and I’m sure a little greener - going to spray her up tonight with Epsom. Appreciate everybody’s in put happy growing - il post some pics in a couple of days and let you guys and gals know how she doing

 

[Jay Bird]

Hey guys just wanted to chuck a picture up.
I gave a light foliar feed with Epsom salts that night. Left her for two days. This is what’s she is looking like two days later since she wasn’t looking so good. Any advice or input is greatly appreciated.

First pic was two days ago

Second was today like five minutes

 

[Jay Bird]

Hi guys thought I’d give another update and have a little concern about some yellow spots - it’s literally just on 1 leaf at the moment and wondering if anyone know what this could be the start of - I personally think because it’s hitting flowering hard now it might be the early signs of calcium deficiency? Any help is really appreciated . First two pics are where the yellow spots are . Thanks guys

 

[Jay Bird]

Here’s some more pics of her now - apart from these yellow spots which I just saw today she has been doing great - @Emilya your knowledge would be very appreciated on this one - she is now 6 weeks in and I don’t know if the flowers are forming slowly because of this - thanks I. Advance

 

[Emilya Green]

I agree that it looks like the start of a calcium deficiency, but I don't think this is causing slow growth. These buds don't look underdeveloped, just young. How long did they say this variety will run?

 

[Jay Bird]

@Emilya hey thanks for the reply, she six weeks old now and they run till about 11 weeks but I have seen a Sativa dominant plant run to 14 weeks and was huge with about 7.5 oz on her.
I have another feeling that it could be early signs of k deficiency as earlier in the grow you mentioned it looked like early signs of a k deficiency when she was like two weeks old and as soon as I added Nutes she blew up - I upped the bloom Nutes up today by .75 per ml so will see. Got a feeling that she wants more jutes and this is where the problem could be.

the last time I watered her with 7 litres of water and had around 700ml run off 10% and she got through that within three days and pot was bone dry .
