I don't grow in coco so I don't know a lot about it but if I recall it has ZERO nutrients init correct? So at 14 days shouldn't you already have a feeding schedule? She looks like she is hungry.

Day 1 to 7 daily watering
day 7 start with dry cycle,
day 11 watered.
Day 12, new growth a bit pale I thought they're just hungry so I feed at 1/10 strength cal, mag, iron and nitrogen.

No vertical growth, horizontal growth very small like 1 cm
Day 14, started them in led 48x3, really pale and yellowish new growth, checked coco run off, ph at 8.7
flush with RO, the run off went down to 7.4
watered them with 6.4 RO water with 1/10 strength maxigro
im hoping this is just macro nute deficiency due to high PH
am I over reacting with this high ph run off?
I really got worried when new growth are really yellowish

Yup, I will flush again tomorrow, I will start her on regular daily feeding, gradually increasing, now that they're in LEDs hope she'll blast off with the nutes

Your LED image seems really red. Do you have the veg AND bloom switches on? (I use the Mars Hydros and keep both on at all times.)

Yup, my bad.I was confused at first didn't know left from right. Now the grow is switched on, during veg you turn them on at the same time? More light spectrum? Does it help whe you use the bloom lights with veg stage?

I've read that it can't hurt. More spectrum. Also the lights fan only works with the veg button on. Not sure if you noticed that or not.

.......Now the grow is switched on.

That should help a bit. Good to hear.
