Uniform spotting on top leaves

[mastergreenerey]

hi guys quick one clone ive had for 3 days has white spots only on the top new leaves. It was like this when i got it. And has not gotten any worse and plant seems fine apart from this. I have checked for mites and it doesnt seem to be that ive checked under leaves all that no webbing nothing no sign of a pest. Ill attach a pic of top and bottom. Any help would be appreciated.

I got the same problem

I'm guessing mine is nutrients burn
I did double the formula thinking more is better.

Maybe you have the same problem as me

I have been looking around and the characteristics of the spotting from what little i have found out its going from leaf base slowly making way to tip on all top leaves which are newest growth seems like it must be iron deficiency. Im just hoping to see regression after recent nute feed ill keep u updated

did you check for mites with a microscope as they cant really be seen with the naked eye

 

[mastergreenerey]

I have looked thoroughly have a good zoom on the camera i initially thought pest but im currently stumped ive looked as much as poss in the past 4 days and absolutely nothing.. see close up below

Current temps are hovering between 24 and 27 humidity is hovering between 60% and 75%. Last PH on feed was 5.81 if that helps at all.

its leaning towards iron deficiency , is your ph pen GOOD

symptoms of iron deficiency in cannabis.

• Yellowing outside the veins of the marijuana leaf
• New Leaves (top part of plant ) affected.
• Young leaves show yellow from opposite tips of the leaf
• Slow growth
• Bigger leaves will start to yellow between the veins of the leaf
• Leaves will start to show signs of burnt tips
• Eventually, leaf will fall off
• Pale green leaf colour
• Veins remain green
• Thin bud development

thats a big pot for a clone ( or pic maybe ) my guess is over watering/feeding causing the iron problems ( lack of roots ) , ( my penny worth ) i am sure others will chime in

 

[mastergreenerey]

Ph pen was not the best but i have calibrated with fluid i bought from growshop. I have only had clone now for 4 days and have fed twice now with nutes. Have them in coco in fabric pots. Given them small amounts of calmag canna a and b, also some rhizo.

 

[NuttyProfessor]

did it have loads of good roots ? if not you need to treat like a new popped seed

 

[mastergreenerey]

It was definitely rooted came with a batch of some of the best clones ive seen. these spots have been here since day 1 not gotten any worse only gave them water first few days. Also in terms of overwatering i have been giving between 500ml and 600ml per 12l pot is this ok?

Thanks for all the help by the way

coco all of it needs to be wet or you get hot spots , dont feed too much 1/4 strength , show a pic of the whole plant in its pot please i am asking as coco is fed daily and if your in a too big of pot it wont help it will build salts

Yeah ive been feeding daily

 

[mastergreenerey]

ive been making sure i dont just pour near roots and feeding the whole medium. Also here is a pic of same strain clone i got at same time (wedding cake). It looks fine none of the spots but let me know if you notice any issues.

 

[NuttyProfessor]

Better , thats your problem , its in a too big of a pot a two litre would do your giving it more than it can chew , put in a smaller pot , half the size of that and feed until it runs out the bottom 20% at 5.8

 

[mastergreenerey]

Yeah it makes sense i have 5l pots at hand will they do? Its my first time using coco if im honest. Previously i have put same size clones into 20l plastic containers with soil and they have thrived, really decent yields aswel but im still getting used to the coco game.
