Please help diagnose (Pics) - I get high with a little help from my friends

Knowledge masters: I seek your assistance

Week 4 veg
H&G Nutes
Sunshin Adv #4 mix

Only a couple leaves on 3 different strains. I initially thought it was splash back from feeds but I've found this on leaves that I don't think I would have splashed.

I want to take care of this asap before it gets worse. Any help would be greatly appreciated.

Thanks a lot!

Will need to see the whole plant.

Here's what you need to post to get quality help on your grow.
(1) Give images under metal halide, cfl or incandescent (no hps), of the entire plant and any close ups that could help.
(2) Give complete synopsis in one post telling us all the details. Now you will have a chance of getting meaningful support because most people here would like to help you. Unfortunately without this info all we are doing is guessing. If you decide to use the wrong guess you may end up potless.

Thanks for taking the time to tell me what I need o provide in order to get good information... Much appreciated!

(1) Give images: Attached
(2) Give complete synopsis in one post telling us all the details. Discoloration on leaves – pictures depicts the best
(a) substrate: Sunshin advanced mix #4

UNWT,
I see some generally dispirited plants. something majorly wrong. One shot showed a Mg deficiency but I know adding Mg will not fix everything. In those small airpots, it might be easy to toxify soil by excessive nutrients. Are you capable of checking runoff ph and ppm? Something is amiss and that would give a few clues.

Why is that? Are you not giving it enough P?

just based on the way the leaves look as compared to several "sick cannabis" guides

unwt,
That's what I thought. But plant problem diagnosis isn't that easy. My point of the question was...why would you have a P deficiency if your nutrients are providing enough? I would bet good money that your plants have a broader problem...rather then a single deficiency. I know for a fact that one plant is showing Mg deficiency. But ph could be way off which would affect nutrient uptake. Or your soil could be toxified by excess nutrient salts in the soil. Or there could be even broader issues related to environment.

so trying to boil it down to a single nutrient deficiency is simplistic. But if you wish, treat the Mg deficiency and the perceived P deficiency and see how they do.
