Saturday morning cupdate, boys and gals!
She is still stretching out and has reached 16" today. Changed fertilizer to GH Maxibloom + GT Liquid Silicone, still 700ppm, PH 5,8-6,2, up to 3 feedings per day. VPD is still high and I've recognized a small Mg deficit. Maxibloom has 5% Ca, 3,5% Mg and 4% S so I hope it dissapears without adding epsom salt.

Required top, side and bottom pics.

More shots are.....

Really regreting pushing you to be in this comp at the moment.....

Next week everyone should post Info on:

Type of light being used.
Medium. DWC SOIL COCO ECT.
Strain. Unknown strains can be bagseed or pollen chuckin.

Maybe @The Dawg can use a word to remind everyone or give a shout out to everyone when you give the word of the week.

I'll put it together. :peace:

LMFAO!
Yeah, man! I hear ya .. I would also not like to compete against me at the mo..

Fact is, the blueish coolwhite from the sides has helped her a lot to create such a perfect shape. I plan already to add 4 more vertical CW strips and maybe a few blue diodes to my veg area later. I'm really impressed!
The only LST method used was to remove half of the auxins by cutting the upper leaves in half but I've done it only 2x.

Something like this?

1. DIY-LED lights based on strips and COB's, 150w top and 23w side light, FS strips switch off when dimmed down but they all are running as soon as I turn up the dimmer.

2. Coco and clay granules 2-4mm, 50:50, handwatering up to 3 times the day

How much did you feed each watering and what's used per day?
I feed around 630 ppms. I feed until I get 20% runoff. If I had to guess its like about 100ml or a little more. 270ppms of that is epsom salts because megacrop (old formula) does not have enough mg for my liking. So 2 grams epsom salts gets me around 48 ppms of mg. then I add mc to get to 630 which is about 1.7grams/gal of megacrop. The mg in that bumps it to 55 ppms mg. I too had sighns of mg on two leaves and bumped it up.
Yeah man a coco mix with clay pebbles will be a bitch to water.
I dont have the correct equipment to play with vpd yet. My humidity stays around 30-45% constantly.
See thats the thing with checking runoff in coco. Reading runoff EC is not an accurate representation of whats going on in the rootzone. EC only measures salt content in a nutrient solution. Organic things have a hard time registering on ec meters. For example, one gram of megacrop (old formula) has around 90 elemental ppm. Their website does not list the ppm of the organic ingredients they list. I did the math and one gram of mc had around 106ppm of organic stuff. So one gram of mc is around 190ppms on an ec meter.
I would say to read your plant and go by that.

Thanks bro!
I really appreciate your insights!
Reading her is what I do from the beginning cause it's my 1st coco adventure. I've used calmag before but only 120-140ppm and it has NPK 6-0-0 so lots of it is nitrogene. On the other hand too much calcium and a too high VPD would cause a Mg lockout so calmag is probably couterproductive.
I hope the Maxibloom formula fits better. Till now only two older fan leaves are affected and I'll anyway remove them next week/when the stretch is done so its not really a problem. But I need to keep an eye on it.
GH says Maxibloom has enough Ca, Mg and S also for coco but on the other hand, adding half a gram epsom salt to my nute soup to bump it a bit more up can not hurt.
Calculating exact ppm's is the next thing I have to learn. With my old school ghetto style and organic soil there was simply no need to do that but I'll stay with coco DTW and redo my bloom area currently and I wanted to do it right.

Heres a good website to start. I fell upon it over a year ago. Most of the ppm numbers they give are spot on. I would recommend to not follow their ppms of nitrogen in the first two weeks and veg. They recommend 200-250 ppms for veg. I suggest 90-140 at max. For preflower watch for mag and cal deficiency because me and you are led growers. A good start is having mg at around 50ppm Still cant find out why plants become cal and mag whores with leds. For flower that number can go up to 60-70 depending on strain sometimes.

That link above has a nutrient profile calculator so you can input all your fertilizers and get the minimum guaranteed ppms per gallon and add up the numbers to see where youre at.
