is this a lack of Mag or N???

Hey guys

so..here's the thimg.

feeding was planned not until the first week of flow (start with a ml of grow the last couple of weeks and then, as soon as flowers start, 1ml gr and 1 blm-3rd to 4th week 1ml gr and 2 blm + some epsom salts. BIOBIZZ) when i saw those fage yelowish marks. they start form the tip and go down (the problem is in its very early stages)..as you can imagine, i was forced to do something and that was inserting approximately 1ml of biobizz fish mix (thought it would do good)...what do you guys think??

ph is 6.9

waiting for your valuable knowledge guys...thank's

need to see the whole plant?

still need to see the whole plant for a proper diagnoses. Can't really tell anything definitive from a couple leave shots. Nitrogen def will start from the bottom of the plant and work upwards as it is a mobile nutrient.

it started exactly as you said bro. the rest of her is just fine (upp until now at least). i will try to do so as soon as possible.

how old is the plant? that's one of the reason I want to look at the whole plant?

please do, it help us help u

keep in mind sometime things start and they automaticaly figure themselves out before your know, it, so take a good inspection of the leaves...

thanks for your concern guys. she is 5 weeks old (give a day or too). the ph is 6.8 and never been fed before in her life (well, yesterfay she ate 1ml fish mix....though it would do her good...wish i knew....so so difficult having everything under control).

I've got one right now, that I've never added nutes or anything, cause of the soil I've been using. Its surprising find, this might be the case for u. Some pheno type don't need nutes especially this early in the game, so do, this is just an fyi thing...

so i should add a little bit of fish (as i did)?..what are your speculations in regards with this thing...i think that she well grown now and needs somethig extra...only i dodnt know what that is.....

naw leave it alone, just give it plain ol water for a while, she might work it out on her own, just keep an eye on her

thanks man... i'll do just that. at least till the next week (flow). what would you use as a start (only have biobizz grow, bloom and fish)?..grow or fish (i've heard that you dont need flower up until you see the first signs of flower)?

Just to be honest with you, I've never been a big fan of adding nutes especially since I make my soil. I've always kinda thought let the soil be the champ of the grow as it were. Maybe its just me. I have seen people who have had good luck with them. But for me natural is always better. Like the current grow I'm doing, I have never had to add any nutes, now toward the end of this grow I've add pinches of blood meal and worm crap, but that's about it. I've handled my soil and put the things that were needed and let it go from there.

My best advice would be, let it go natural you might not have to add anything as it were, and if you do, start very very small then work your way up and go from there, everyday there will something new, and don't worry she'll tell ya what she needs. They seem to do that.

thanks for your valuable help mate....i will try to proceed like that and see..

no worries, let me know how she's doing

happy growing

looks like you just need a good dose of cal-mag

i dont know if Cal is one of the factors causing the problem but i dont think that Mg is the real problem. If there is actualy a Mg problem. leaves are turning yellow (at some point...finally) and the whole thhing is escalating (since the plant needs to consume more as it grows) as days go by. Checking is a daily procedure and i havent seen drastic negative changes. the rate seems to have stopped. If it didnt, then it is soo slow that I cannot observe it in surch a short time period.

i only have biobizz grow, bloom and fish mix so if i need an Cal addition, i am just going to mash some egg-shells (make it like dust) an dmix it with the soil. what makes you conclude to such outcome?...why Cal?

calcium is a catalyst for the plants, helping move the nutrients absorbed by the roots up into the rest of the plant, and is important for strong cellular structure.
that being said, i only said cal-mag because thats the traditional way its packaged for cannabis. you don't actually look deficient in calcium, but its hard to overdose a plant on it, and it helps with the uptake of the magnesium....which is what that looks like to me, the beginnings of magnesium deficiency.
mag deficiency can be caused by poor drainage, or low ph. your ph seems to be plenty high, so maybe your soil is a little dense?

thanks for the tips man...exactly...my soil is a qute dence (well, only in the region that the old soil was...you know...the one that has been transplanted to the new one)..but it drains quite frequent instead of having poor drainage. when i first noticed the problem i was sceptical cause i new the soil's good condition and nutrient supplements (it is not normar though to have such a deficiency at that stage) that it contained...anyway..as soon as i saw the problem i added a ml of fish mix in 1lt of water (4 days before and since the i havent noticed an expansion (at least not any that can be detected in such sort period or time).

would you use the egg sells? would you use the fish mix (biobizz) instead of their grow supplement?
and most importantly, today is the forst day of flower..do i have to do something extra (besides the combination of grow and bloom that i am planning to start with the next feeding) in order to deal with the problem (athough...i am telling you...doesnt seem to have reached higher leaves nor the all the leaves in a single branch (for instance: it has caused more fading yellow marks in some smaller leaves but it remained as it was since then and didnt spread iin all leaves of a single or multiple branches).

thanks for the help

egg shells will work, i haven't used them myself but a lot of people do.
i stay on the same feeding schedule for the first two weeks of flower that i used for veg, and slowly drop most (but never all) of the N, and start adding more P and K, during the third and fourth week, by the 5th week they're getting maybe 10-30-50, at about 500-600 ppm, and will stay there for the rest of flower. the last watering they get is always just ph'ed water, not because i think it "flushes" anything, just seems like a waste of nutes to feed a plant thats coming down in a few days
