Calling all experts! Plants becoming yellow, brittle, and blotchy?

Hey guys! Noob needs some help here. I started my first ever coco grow and Ive already encountered problems a couple weeks in.

Grow Specs-
Medium- 70/30 coco (washed) and perlite mix
Nutes- mix of 70% Dr. Earth all purpose 4-4-4 and 30% Dr. Earth Flower Girl 3-9-4 (1 cup every 5 gallons of medium, just as the bag states)
Water- dechlorinated tap water PH'd to 6.5-6.8 and watered when the cups feel light.
Light- Hipargero 800 (240 actual watts) mounted about 30-36inches inches away.

Im sure some of you know I copied Mr. Canucks Grow style from u-Tube. He makes it look so easy (and cheap) that I had to give it a try. Well, long story short, something went terribly wrong and my plants have some issues before I could even transplant. View attachment 4337790 View attachment 4337791 View attachment 4337790 View attachment 4337791 Some leaves are starting to yellow and some have rust spots and are becoming twisted and brittle. Idk what it could be.. Anybody know based off the photos and info provided?

Well they were all droopy until I soaked the medium (before I was just using a spray bottle). Once I used a bit more water, they really perked up, but the color didnt improve. Reckon I could've been underwatering instead?

Ya probably underwatering then. I use promix so I let it dry out and water whenever the pots are scary light without leaves drooping. I'd wait for other people who have experience with coco to help with watering habits but ya it looks like its just a watering thing to me.

Bro, It needs watered daily, its coco and perlite, it HAS to be watered daily. Also, your PH MUST be 5.8, because it climbs in Coco. AND, its to much light in the sun.

Its just hungry.

AND, it needs mag.

1g epsom salt per gallon of water

AND, you cant dechlorinate water, only thru a filter, sitting it out does nothing, or boil it.

alot going wrong here, your lucky you can fix things before they get worse,

All about learning, not scolding you man,

Canucks uses a promix im pretty sure, which is OK to let dry out a bit, but coco WITH perlite, best to water daily. If it was just coco, 1-2 days without water is ok, top dry, but dont let completely dry.

Scold me if thats what it takes lol. Nah but Canucks uses Mococo (just like Canna coco).
I water daily, but not a whole lot at once.
I only had them in the sun for pics. Theyre usually under a 240w light.
I also use cal-mag every other water or so (should've listed it)

ok, i thought so about the sun, just transplant, and calmag everywatering, its important. photosynthesis relies on mag especially, and 3 weeks into Flower, stop the cal, and just mag, ( 1g pergallon water) every watering.

flush every other week, with a good watering, phd

great luck bro, grow on

Turns out that roots grow way faster in coco. They were root bound. I transplanted anyways. Worth keeping or should I start over ya think?
