Looks like you have overwatered the plant, maybe also incorrect pH

Over watering, too much nitrogen (curl), and possible micro nutrient deficiency or lock out. PH?

Problem in 5 Week of Vegetation
Now in the 5 week of vegetation. The plants are Tropical Gelato cuttings. Everything was great until recently. They looked great. After another light fertilization, the condition of the plants continued to deteriorate. Soil PH value is between 6 and 7. Can Someone help?

Yellow leaves question.
Good morning growers, I have noticed some yellowing of the bottom flowers on my one of my plants. Everything else looks extremely vibrant and healthy. Does this look like a watering or nutrient issue? Or is it something I should not be too concerned with ? Thank you everyone :)

pH maybe?
Check out the Northern Light leaf, is this single leaf thing to do with pH? Was I a little bit too soon with the Nutrients for the small plant?

Defoliate yellow leaves?
Should we remove these large yellow crusty leaves near the soil? The plants are at about day 38. I've heard people say you shouldn't defoliate this early in flower. Should I be concerned about these leaves dying off or is this normal?

White developing on leaves
Hi all. Very much a newbie question so apologies for poor knowledge. Just stared 4th week of flower and opened the tent to see the leaves on one of the plants developing white hairs. Is this ok? Or something to be concerned about? Many thanks. 👍

Whiteish damage
Anyone know what kind of damage this is or if its anything to worry about? A few spots like this on some leaves but not much. definitely doesnt look like mold or anything like that up close, its more like that part of the leaf has shrunken and whitened.

Wondering if the amount/type of yellowing leaves is normal at this stage? Seems like maybe a nutrient defeciency (maybe burn? I dunno!) but given the stage of flowering not sure what should/can be done at this point. Have been providing ~1/2 dose bloom nutes (9-16-16). Thanks!
