Plagron light mix Question!!

Hi guys i have 2 babies in light mix under a 150watt hps and some cfl/t5s .
I have only been watering with phd water and im just wondering if anyone uses this substrate and if so than when should i start my veg nutes?
i have biobizz grow, and on their schedule it says i should start after first week,and the packaging on soil also suggest the same.
Babies popped out of ground on the 27th and im not sure if i should start the feeding because they seem happy for now but i dont want them getting deficiency's.
Any insight would help me out greatly !!!

Plagron is lightly nuted so you shouldn't need to feed it anything for another couple weeks. You shouldn't need to feed it before the cotyledons turn yellow as that is what it feeds the plant till it establishes a proper root system.

sorry for only replying now man , this sites notification system is kinda dodgy i find people answer me after 10 mins and it wont show unless i go to the thread itself.. anyways thanks man i kinda new the cotelydons need to yellow of but im getting my third set of true leaves and well i ended up giving about 1/4 strength grow nutes.. it is bio so i was like theres no way ill over fert them .. they seemed to like it and are happy so far..

Just cause its bio doesn't mean you cant burn burn it. It just takes longer, Good Luck

it will be fine for a couple weeks if you have in a large pot. I use 5 gallon smart pots and the same brand of dirt.

Ok thanks well heres a pic of the 2 of them both 15 days old, ive just moved the light z bit closer today and they sem to love that..
