Yellowing getting worse but not sure it it's too far gone week 7 of flower

i recently had a PH lockout from lack of run off, so after flushing and giving them straight water for about a week I've noticed yellowing slowing down but it's still killing itself off slowly. Now I Checked the ph of the run off and it's about 7.2 and at about 2000ppm. Any thoughts on if I can wait out the last week and a half to pull them or would it be too much of a chance for the plants to turn hermie due too stress? I don't want to pull early but if it saves my Harvast then I'll do anything. Btw I'm growing GG#4 in soil

Run it out until the trichomes say they are ready. 2000ppm following a flush? Holy cow, less is more brother.

I usually do, but this is the first time I tried a scrog, but sadly I had problems so I had to cut my net. But I'm worried that they'll hermie out from the stress before the trichs are ready. And I know I always fed them because they seemed to be really loving the nutes up until 2 weeks ago.

I'm using humboldts organic line for the first time too. I know they say to issue half or even 1/4 of what the nute feeding schedule says, but I guess I just assumed that only applied for conventional nutes :wall:

You want them to yellow out at the end and about 1/3 amber trichomes. The yellowing at the end (if your flushing correctly) means the plants are final feeding from foliage, finishing the life cycle and leaving you with nutrient free fruit. One way to tell if your getting a good flush is the burn test. Roll one up, start smoking it, it should burn and leave ashes more like a cigarette and not very black. BTW, that ph is way high, you should flush them with plenty of ph balanced water.

But the yellowing is starting up top so I don't think it's doing that because of the flush. Most of the bottom foliage is healthy looking

Depending on the strain u may want to just give them a few days and chop, hard to tell but look pretty ready.

I see: leaf tips burnt, not good. That could be nutrient burn or a ph issue. This far into the flowering phase I would flush and flush until your runoff has a ph of no higher that 5.6. The yellowing of the shade leaves is normal. FYI, it will take a lot of water to flush them.

If your not in a perpetual system I wouldn't worry about them turning herm on you at this point. Let them swell and finish. Flush for a week or longer

I never say I'm going to harvest in X amount of days. The plant will tell you when it's time. Ever seen a farmer harvesting wheat in February?
