Leaves Yellowing (Week 4.5 Flower)

So I thought I had a yellowing problem under control, however it seems to be worsening. Here's my details, this is my first grow

6 DJ Short Blueberry under a 600w HPS
Soil is a 50/50 mix of Fox Farms Ocean Forest and Happy Frog
Vegged from clone for 4 weeks, today is 31 days into flower on an approximately 60-65 day strain
During flowering I've been watering at full strength with Tiger Bloom and Big Bloom. I've been PHing the water to around 6.5
I water approximately every 3 days, with every other watering being a full dose of bloom nutes, and the other being PH'd water with molasses
My soil PH is approximately 6.2, I have an analog meter, digital too expensive for this grow

Any ideas?

n deficiency.

Thanks for the quick response. I thought the same thing but I've fed them Grow Big three times now in their flowering period, I had assumed that would take care of any N deficiencies

Have you been flushing?

I'm using the Trio too and I'm having trouble keeping up with N deficiencies. Honestly, I'm just not very happy with this line of nutrients. In your position I would give them a 1/4 strength feeding of N for another week and then just let it be.

It's just too late in flower to keep feeding N, but if the plant didn't have enough stored up they ARE going to go yellow and I don't think there's a whole lot that we can do about it. The only good thing I can tell you is that you don't N for flowers. Yeah, you'll lose leaves, but you'll still be growing buds. Try to give them a little bit, but after 6 weeks it's never done anything positive for me. After that point I've actually found that the yellowist/lightest plants that I gave up on feeding N actually had bigger buds.

In response to lovemug

Not really. Like I said up above, about a 6 day watering schedule.
Day 1 1/3 gallon per plant with a full dose of Tiger Bloom and Big Bloom with 2 tablespoons of molasses per gallon (Water PHd to 6.5)
Day 4 1/3 gallon per plant of Brita filtered water, 2 tablespoons of molasses per gallon (Water PHd to 6.5)
Day 7 1/3 gallon per plant with a full dose of Tiger Bloom and Big Bloom with 2 tablespoons of molasses per gallon (Water PHd to 6.5)

etc.

This past molasses only watering I did up the water amount to a 1/2 gallon per plant, that was two days ago

Im using the full line up including the Sludgehammer for scheduled flushing. Im about 7 weeks into flowering and am liking the results. I was only using the liquid and trio. The microbrew and kangaroots seem to be the same thing but they are only 40$ every year mayby for a grow my size so i dont mind spending the extra cash, i get plenty of meds using them.

Fox farms has crazy salt build ups and is a pain in the ass sometimes but for the cost i love them. I wish i could afford to start running Advanced nutrients but its not in the budget.

If you continue to use Fox farms i suggest you atleast pic up the trio and Sludgehammer. With sludgehammer being your top priority. If you do have heavy salt build ups preventing your plant from taking up nitrogen i dont think there is much you can do at this point in floweing. If posible i would flush them and hit them with a dose of grow big.

Anybody think that my soil PH of 6.2 could be causing a nutrient lockout?

Here is a pic of my flowering room at week 5.5 weeks running the full line up plus Advance nutrients bud candy. I am definatly getting a lot less yellowing than when i was not running the new Bush Doctor line Fox Farms came out with.

that does appear to be a nitrogen deficiency. i wouldnt worry too much about it, as you said you are about 5 weeks into flowering. many plants start to turn yellow later in the flowering stages.

According to this View attachment 1928394 might as well. I had similar problem to start with, ignored it and it only got worse and worse with other deficiencies showing up, but that probably was down to me not giving my plants any micro supplement. I wouldn`t be too concerned if it`s just yellowing at 4.5 weeks.
