Mag Def?
PricklyPetestarted grow question 3 years ago
Does the yellowing between the veins on these lower leaves look like a magnesium deficiency?

InspireMeanswered grow question 3 years ago
I agree, looks like mag. Be careful when removing leaves as if the deficiency is not corrected she will start taking nutrients from another leaf. Causing more damage to the plant. I'd leave them on for a a little longer in future. You can cut the dead bits off without issue, if you like.
Hope this helps 🙂

Thank you @InspireMe and @hashy for your feedback, it was very helpful. I did some further research and agree with your opinions that this is Mg def.
the pH is 6.5 so I'm quite confident that they just need some Mg.
Fed Cal-Mag a couple days ago for the first time and I think the spread of the yellowing has slowed. Should be back on track soon, thanks again!

Looks like magnesium deficiency. Is your ph in range.

Can anyone tell me what's going on in week 2? I transplanted and each plant seems to be yellowing on the lower leaves. Not very happy.
Was dry when I took it out of the dixie cup and watered with 1/4 strength veg nutes and a root stimulator.
It seems to be curling in as well.Week 2

well it looks like i'm facing nitrogen deficiency.
the leaves are pale on both plants and also plant 1 has very small tiny leaves and leaves turning yellow.
So i think it's nitrogen? i will put 1 ml more of coco bloom A to correct.
if anyone has another opinion let me know.Week 6

Ok, so I’m starting to see a deficiency. Yellowing between the veins at uppermost leaves. My ph is on par. I’m maintaining my grow per normal with one change. I added Carbo load at 2ml/g.
Could that be the problem?
I think I’m going to flush today and dump my tank. Restart.Week 14

I seem to have some yellowing on fresh growth starting to occur. I'm not too sure how to prevent it. I have started to do some LST and find it to be successful and a lot of fresh sites have appeared and wonder if this could inhibit it by stressing the plant?Week 4

Pic week 7 (2/3/19).
Last couple of days started getting this discoloration on a few.
Had deficiencies in past but were usually spotty & random which ended up probably being calcium def...have added CalMag this go.
This is spaced specifically in between the veins. Please&TY.Week 7

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!Week 10

I have uploaded a few more pictures - getting worries as the yellowing is continuing. Any ideas?
pH was 5.6 on Saturday when I first mixed the nutes), and then with the air stone has come up to 6.5 or so. I've added a small amount of pH down to temper this back down.Week 7
