Welcome! :) My question is it too early to start giving nutrients? When is it recommended as something is wrong with shark attack already but the new growth appears to be OK, as you can see by the pictures the lower leafs on the shark attack looks kind of brown grey.

You give us no information with which to work with. Anyway, that is not a nutrient deficiency. A plant that young should not be fed. It does look like a pH issue, get a pH meter, meassure your water and adjust accordingly: 6.5 is ideal for soil, but keeping it between 6.0 and 7.0 is fine. Don't think of giving nutes, let the plant feed itself from the soil and then, trasplant to a bigger pot. In case you care, LED bulbs are much better at growing weed than CFL.

At what stage do leaves get darker ? This is confusing I overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more. I've had tips burning probably from light too close. I find that leaves are pretty dark but it may be because of the strains. When leaves do get darker in flo ?

Dark tips it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.

Seeing some top bud leaf discoloration Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity
