Three strains. One problem

I currently am running an indoor grow with 5 plants and three different strains. One of my GDP's is obviously deficient in some macro-nutrient whereas the others are not. If i want to correct the problem on the single plant alone, should I foliar mist with the missing nutrient on that single plant. Or how do you all suggest going about correcting deficiencies you see in one plant in your garden?

...try to post some pics

Here's some shots. What do you guys suggest?

...how long have you had them in those pots? ...have you fertilized them yet since? ..if so, what have you fertilized them with?

I am in day 25 of veg. Started them in the pots you see in the pictures. No transplanting. I am using AN's three part base nutrients with the addition of humic acid and superthrive for veg. I have fed them once on day 16. I am planning on feeding them at the next watering.

if i had to guess id say they want water more often. that soil looks super dry and plant could be suffering from that in addition to lack of nutes

My two bubba kush's and two trainwrecks look great. I only have a problem with the single GDP shown. Do you think the others are thriving because their nutritional needs are being met, besides the one GDP who may be lacking due to its predisposed nutritional necessities.

so the curling is due to under watering? I watered 2.5 days ago and the soil still contains moisture:/ Main question though. When growing multiple strains with multiple needs, what is the best way of going about feeding and catering to each plant
