My leaves?! (help needed)

[Bambikush420]

What's going on here guys? Is this a deficiency? Mg def? It was just the lower ones at first now the top ones have taken little brown marks

 

[Bambikush420]

Ignore the color its not that green IRL, is this overwatering? Not enough nutes? I've just started feeding them

Problem: twisting of leaves and brown spots

Medium/grow method: coco n perlite

Feed: and supplements used: Grow Micro Bloom, B52 and voodoo juice by advanced nutes, also plant magic calmag PhD between 5.9-6.2

water source: tap water left out in bucket for days to dechlorinate, (I live in a place with some of the cleanest water in Europe)

Strain/age: glueberry og auto

light used: hlg 550 480w LED quantum board

Climate: between 19-26 celcius 50 humidity

Additional info: plants been on 1/5 strength nutes from day 7, before just water at pH 6, 1/1/1 GMB and then 1 voodoo and 1 b52, also 1 calmag, just started feeding them a 0.5 dose across the board about 3 days ago,

Looks just fine but do not overfeed when there this small.

... hmmm, first true leaf, not much to sweat there... it looks like Ca defc., just a touch, maybe pH was off for a bit... coco also hogs it, part of it's bitchy CEC properties! Is it RTU coco, or from a brick? Brand? Sometimes those need a good pre-rinse before use, with a Ca-Mg solution which will help b set and buffer (not pH here) the cation exchange capacity with Ca and Mg,... these bind very strongly to coco particles, so much so that the roots can't take it up...Once sated, it'll give/take like it should,... stay on the nutes, and make a mild foliar spray with the Ca-mg, 1/2strength; use a wetting agent to help it coat and stick better (more absorbed), and get leaf underside especially , more stomata there, more absorbed as well,... castile soap can do in a pinch, just a bit, enough to make the solution not bead up when sprayed.... this is the fastest most direct way into the plant.

Hello mate, the coco is canna coco professional +, I'm not too certain of its properties as I can't find a great deal of clear information about, thanks for your answer, she's a bit bigger now and there's still the same look to her, slow growth mind, just started putting nutes back in at half strength yesterday, hopefully she takes kindly, soil pH is around 6 and I'm watering in at 5.8. Fingers crossed. Definitely gonna do that cal mag spray, can I just use calmag and water?

:smoking: In the coco section here are some good info resources about it,... CANNA is good, so that's a plus,...BTW they have a great site full of info too!

Yes on the foliar, but lacking the wetting agent it will be less effective,... not as much absorbed

Mine are also acting weird they are curling at the top like you would curl your tongue and some of my plants are growing sets of 9 leaves
