2 Plants. Different Defs??

I've read too many Plant Deficiency, Problems, etc and I feel lost. Im confused between Mg, Fe, S or Ca Deficiency. Need a hand.
Plant 1 (Unknown strain, 100% Sativa)







Plant 2 (Unknown strain, 100% Sativa)

what nutes have they been fed? and how often? soil?

No nutes whatsoever. Soil with mixed manure.

what kind of manure? and what was the ratio to soil?

70% Soil
30% Manure
Veg Compost

looks like your PH is off, due to the twisting leaves...which is causing a lockout of some kind. most common is calcium or magnesium...but it is also looking like zinc, and yellowing from the tip inward could be a few things...i want to say it is an immobile nutrient lockout, which one though man is kinda hard for me to pinpoint...i believe the nutrient locked out is immobile, which narrows it down slightly to like 5 different deficiency's. i would flush with PHd water, and hit her with some cal mag plus...plus has chelated iron in it, so it would knock out 3 of the possible culprits.

i would also make sure to flush with the cal mag plus...like 1/4 strength recommended.

I don't have access to products like cal-mag or miracle grow. Can I replace those with dissolved calcium and magnesium tablets on a ratio of 1 100mg Tablet / 1 Gallon????

Hmmm. Not so sure that would work. But if you were to try it, you should grind that stuff up super fine. and I mean GRIND. Then add it to like 1 quart of boiling hot water and mix heavily. Then add this to the remaining water. and then cool to 65-68 degree's or what ever floats you boat.

Hold on here. You do not have access to cal/mag or MG? You are not able to get mail? What kind of soil do you have? Where did you get the manure? You did not save up your own turds did you?
Really, what are you growing with? And if those are unknown strains, then how do you know they are 100% sativa? You know how hard it is to find 100% sativa plants? or 100% indica for that matter.

do you have access to molasses?? this is what 1 table spoon of Brear rabbit unsulphated molasses contains:
60mg calcium
24mg magnessium
1.44mg iron

i have crushed up B vitamins to promote root growth before and i does help so your idea will work... as long as you crush them to dust(use a credit card like the drug addicts do)! crush your 100mg calcium pill and use only half of the powder... dissolve it in some water a cup of water then feed your plant that. and i guess crush 25 mg worth of Mg and put it in your special cup of water with the calcium too. viola homemade cal-mag!! dont snort the powder lolz

DirtySnow has a valid point there. Black strap Mollasses.

Thanks for the input. Here's an update.
Plants are lime green.
Plant 1






Plant 2 Complete stunted growth





Plant 1 n 2

We need information. But this started 3-4 weeks ago. So it is time to fix the issue. More info. please! Some people are saying give it cal/mag. That might be, but it also could be 4-5 other things. And why can you not get any cal/mag or MG? What is up? You stuck in prison or something?
Help us, Help you. hahaha
Also, where did you get your soil?? What Brand, or did you just go dig up some dirt out in the back yard?

Soil from a farm.
Temps 22 to 29 C.
Vent is good (2 220V fans in|out, 1 inside).
Light is 120W LED,2x45w CFL for now.
Using 1/4 strength of this:

burn tips are signs of a nute burn, but you also have a magnesium and/or zinc def, they look similar by nature.
