Third time's the charm?

I've posted three times and I really haven't gotten any help with any of my problems that have been plaguing me. Lots of people stating the obvious that they don't look so hot, but no one offering any suggestions or helping me determine the problem. So I'm going to give this one last shot here. These plants are near 10 weeks old, and I give them nutrients ever 3rd watering. I use M.O.A.B 0-52-32 and Hammerhead 2-4-10, as well as some epsom salt once, and sulfur free organic blackstrap molasses. I use tap water, but I'm not sure of the PH. I've ordered a PH tester and hopefully my PH is fine and my problems aren't related. The first plant that will be shown here is doing significantly better than the second however took much longer. It's starting to show some of the symptoms the first one started showing around now, rapid defoliation due to yellowing of leaves, as well as crispy dried tips, doesn't look like a burn. The second plant is having its leaves turn crispy and yellowish even into the bud. It has me really worried and I'm not sure if it's going to finish, I think it's almost about time to flush and I'm not too sure how it will respond to that... Here's the pics...

Any help or recommendations would be really appreciated. Some other things, I'm growing in ProMix soil, didn't add anything to it. Temp is stable ~85. Humidity 30-40%. Good ventilation.

Please? anyone?

How much of the 0-52-32 are you feeding? You're probably using way too much of that.

Also, stop feeding epsom salts unless you notice Mg or sulfur deficiencies. It will just block out other elements that are actually deficient.

For late flowering it suggest 1-2 tsp per 5 gallons, I use a little less than 1/4th tablespoon per gallon. Is that too much you think?

And I've only given it epsom salts once or twice throughout its whole life.

I'd quit giving it the KDP 0-52-32 for now entirely, the soil probably has a lot in it. What it looks like it needs is more N.

The flowers look really good otherwise.

Should I wait longer to flush? I don't want my first product to taste like crap, I don't want to mess that up. I'll give them more of the HammerHead we'll see how they respond.

Fed them 3.5 mL of HammerHead 2-4-10, it suggests 2mL per liter of water, a gallon = 3.7 liters, I gave them about 4mL total, is this perhaps not enough? Now that I think about it I realize I only was doing 1 mL per liter. Silly me. I gave them a pretty heavy watering, so I hope that's enough as they won't be dry for some time.

Since feeding, it would appear that the yellowing has gotten even worse. I'm at a loss as to what to do. I don't want to keep adding things if I'm not sure of the problem. I really need help guys.

odds are .. your burning them ... start hard flushing add yucca extract to 24 hour old tap water give good 3 ish days of flushing water.. then brew compost tea and apply to soil without nutes in it. Top dress the soil and water it in with compost teas.

if your completely against that ... hard flush with yucca extract and water then cut your nutes 1/3 of what your using now when watering and make sure soil is draining well and airy.

and deff lay off of the epsom salt

I'm not an expert but I'm fairly positive it doesn't look like nutrient burn.

Anyone else think it's nute burn?

I now have reason to believe it is a nutrient lockout due to a low Ph of 5.5 measured by the runoff. My water ph is around 6.7-8 going in. Might this be my problem? How could I fix this quickly and safely?

That means your soil has a PH of around 5.1 which is way to low.raising your PH should help this and your water PH should be around 6.4 so slightly lower IT.if it was 7+ thats gona burn the shit outa them.give them no nutes for a week only water at correct PH and hopefully problem solved
