Nutrient question_

I am hoping to get some answers to a reoccurring problem that I'm having with my plants. Everything goes well until about the 3rd week of flowering, when the big fan leaves start to yellow prematurely. I know this denotes a Nitrogen deficiency but I am supplying the girls with Earth Juice (grow) or Fish Emulsion from the time the seedlings are about 10 days old all the way up to about 3 weeks in. These nutrients are both organic and High in Nitrogen. The yellowing starts even before I switch to a bloom formula which of course contains less nitrogen then my veg nutrients. The yellowing occurs way earlier than it should. I grow in home made, rich organic compost, and never use chemical ferts at all. This problem is undoubtedly costing me a significant loss in yield. Can someone please outline what I am doing wrong here? I don't have any pics atm, but as I said; My plants are vigorous and healthy green, until about 3 wks into flower. The yellowing starts BEFORE I even switch to a lower Nitrogen Formula for bloom. Obviously, the yellowing gets worse, after I switch to my flowering fertilizer (Earth Juice Bloom), but the ONSET of the yellowing starts about 21 days into bud. I don't want to run out an buy "better" ferts, etc. as I think there is nothing wrong with Earth Juice in the first place. I don't want to give them more N in flowering because as I understand it, the plants should receive less of it when budding. I have no idea WHY they do so well during veg, and suddenly a few weeks into bud the fan leaves start yellowing at a faster rate than they should. I know bud production DOES require N and am speculating that maybe the plants are pulling N from the fan leaves in order to supply the buds. Should I Increase the Nitrogen during flowering? Earth Juice is all organic, and not likely to "burn" the plants, but I don't want to "retard" my bud growth either. Can someone please help? I am sick of seeing this phenomenon in my garden :wall:

Maybe your homemade, rich organic compost isn't so rich? I'd suggest amending your soil with an amendment that contains more N while sticking with 'grow' until the end. I'm assuming you're transplanting to bigger containers a couple weeks before they flower, right? Your compost should keep them green for longer than just a few weeks.

had the same problem and was also using EJ. started cooking soil and using it as a supplement until i figured out my soil recipe and then this last run, i'm using a super soil cooked for just over a month, and water only and it is doing better than running just EJ grow/bloom.
