Deficiency???

[Cbdt8i]

Hi all. I've been coming to the forums now for about 3 months. Im a rookie but I know there are a lot of the different deficiencies when it comes to cannabis and pH problems. I have 2 plants going right now that are autoflowers. One is a blues Auto and the other a toof decay both from Mephisto genetics. I think I've narrowed it down to a couple problems. Either a magnesium deficiency, phosphorus deficiency, or potassium deficiency I'm not sure. I did stunt them both for about a week with a little over-watering in their first week. The toof decay was hit hardest.(in photo) I also thought it might have been nute burn because the oldest bottom leaves turned yellow and died off, yellowing started from the tip. Any help would be greatly appreciated. Also if I could getsome pointers on what to do to fix the problem. I do have some Cal Mag so I'm thinking of starting there if that doesn't help maybe adding a little dr. Earth's. I also checked the ph of the soil. Its 6.6-6.8. So i know its not a ph problem. I feel like i should add some cal-mag(which i havent done). Then hit it with some dr earth tomato and herbs, only because i feel like it nay need some nitrogen???

OK I see you checked your soil ph, but what soil mix is it that your useing? Have you checked your run off ph?

Looking at the pictures it sort of dose look like a call mag problem, but since the spotting isnt all over I have to say that dead leaf as well as the discoloration your plants are experiencing is most likely to stress of the over watering, ( please note this is dose depend upon your soil mix and if your useing any thing that has a delay in your nutes witch is most liquid nutes)

Im using fox farm ocean forest soil. I also added some perlite, mushroom compost, earthworm castings and i took 1/2 cup of dr earths tomato and herbs and 1/2 cup of dr earths bud and bloom i mixed it all together. I started in solo cups with nothing but ffof soil for about 10 days and transplanted. I know i should of started in the final pot but i didnt. I also found that i should have only used this soil in the bottom half and plain ffof on the top half. I def will next round.

oh! I would say that is due to the transplant and that makes Alot more sense lol, good choice of dirt imo and as long as your nutes are powder and mix In per gallon iv never used Dr.earth products but usually with any nutes with auto feed them at half or even less then the recommend dose for a normal plant, you can up or down the feeding as you see your plant respond good or bad, ( it seems like Dr. Earth is a mix you put Into your soil? If so it is a time release thing and that's also not good for cannabis plants imo)

.... this color break, is it on all the leaves, from day 1? ( positively not Mg defc. BTW, not the right symptoms).... If so, this isn't a nute issue, it's genetic,.. we see this fairly often here, sometimes the plants performs OK, or not,.... clears up, or not,... and a more remote rarity but shit-show grade FUBAR is a viral infection,... that is hard to determine, requiring the right kit to test for a specific virus, there's no "broad spectrum" test that covers several kinds at once,...
