When do you start adding nutes

My seed has sprouted out of my rockwool cube. At what point do you start adding nutes? My seeds sprouted a very pale looking brown. I'm worried my water may not have been at a ph of 5.5. Any other reason they would be this color? Thanks in advance.

In my opinion, in Hydro, any pH between 5.5 and 6.5 is OK, 5.8 to 5.9 is best or works best for me.

Newborn Babies are born hungry, ready to eat, but they can not handle a T-bone steak or a Mcdonalds Full Meal Deal. You start them slow and gradual.
Mine sprout with two round leaves, do not count those as leaves. I wait until the 2nd or 3rd day, when I see two full leaves, and I add 1/4 strenght nutes. I wait until I see the 3rd and 4th leaf, or a 2nd node about two or 3 days later and add 1/4 again.....adding 1/4 again in 2 or 3 more days until I am at Full Strenght.

Let me make sure I have this right. The first two leaves need to be ignored. Then, when a second set of leaves comes in add 1/4 strength nutes. after three days, then add half strength. Next watering add 3/4 strength and then full strength.


I just want to make sure I understand and also I'm repping you. A big thanks.

yes, each step, add an additonal 1/4 until you are at 4/4 OR at full strenght.
