is this a lack of Mag or N???

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

thanks for the tips man...today is the first feed (except the one that had the problem..in tht case 1ml of fish mix had been injected 5 days before..seemed that the problem stopped in a way..maybe, as said above, she finally took care of herself) and the first flow day...so i am plannig to start with a ml of fish per 1 and a half lit of water on both (per each). i noticed that the fish mix has higher percentages in Mg that is why i thought that it would be much more usefful than the grow (biobizz) the first two weeks (which is more needed...right?) of flow.

i intend to change it (the fish mix) during the third week of fllow with the grow which is lower in Mg but higher in the P and K (Fish mix: N:5 P:1 K:4---Grow: N:4 P:3 K:6) and go along with a combination of grow and flower from that point on....Am i in the right track (hope so)?

it one thing though that i am not sure and that is the amountsof food needed. Can you give me an examole (considering that i am workimg with biobizz)?

for instance: i started with 1ml of fish mix the first week (curent week) and the second one i am planning to stay on 1ml fish (which i am going to change during the third week) AND 0,5ml of bloom (thought it would be good for boosting the flowers). The 3rd week: 1ml grow AND 1.5ml of bloom + (if needed) a little bit of epsom salts (completely irrelevant that i dont know shh....t obout how to apply it?,,,dont think so..but alll in time) and so on...am i thinking right or should i do something different?

i've never used biobizz, but here's their schedule

i'd suggest using about 60% of what they say to use to begin with and work up from there, the estimates manufacturers give you are almost always enough to burn the crap out of all but the hungriest strains.
i add 1/2 tsp of epsom salt per gallon of water every watering during veg, then i switch to a product called sul-po-mag during flower. its basically epsom salt with some K added

Looks like magnesium deficiency. A solution of epsom salts can be a cheap fix

thanks for the valuable info's guys (and for your concern...feel more secure). is there another way to add more K in a more natural way (wish i had the sul-po-mag that you said)? i mean that special extra addition (if needed). I know that wood ash is one solution but it raises ph so i dont want to get down to this.
