Fed up until harvest. Cut nutes back significantly the last couple of days. TBH, I've been under fertilizing a bit, so there was no need to flush. Next go around I'm going to up the feeding schedule at bit.

It's very old cut of Grape Ape (aka Grand Daddy Grape Ape). When it's cool in the winters, she gets really purple - almost black. Unfortunately, not the biggest producer, but what she lacks in quantity, she makes up for in quality. :eyesmoke:

Looking to replace Kool Bloom Dry in my feeding schedule (2-45-28). I'm seeing P toxicity and K deficiency in my plants so replacing Kool Bloom Dry with something more balanced is an obvious choice. I got a sample of Lotus Boost 1-15-30 and things perked up, but my local hydro shop hasn't...

I think you may have a few issues going on. I don't really see iron deficiency per se. I'd let her dry out and then flush and start with a balanced feeding schedule.

J/K.... :P

I think I may have pulled her down a little early.....

It's not easy. I've been doing this a while and still run into issues. Recently I flushed thinking I had a lock out - the plants didn't like that at all since it was deficiency, but at least it was pretty apparent after the flush. Do you know your EC? Are you using the lower or upper range...

If you're just using Big Bud as your bloom booster, then maybe it is underfed. I was referring bloom boosters like Kool Bloom Dry with PK #s in the 30s, 40s, 50s..... Nevertheless, I've seen similar results when using bloom boosters - the lower yielding plants can't take as much PK. Given...

That's the Blue Dream turning "blue." However, it's ~2 weeks ahead of schedule. Are you bombing it with a PK/Flower booster? If you are, my guess is the bigger flowering Hemp is using up the additional PK and the smaller Blue Dream isn't using as much PK, so you get the narrow leaves and...

Iron deficiency. Foliar feed them some iron. Looks like they need nutes in general. I'd foliar them with a broad based foliar (Dynagro Foliar comes to mind) and some iron (Cyco Dr Repair or Fertilome Iron). You need to put those guys on a nutrient schedule. Don't go too crazy with nutes...

Bigger leaves will droop. You'll see alot of guys cut them in 1/2 to avoid that. If you took the clones during lights off or just before lights off, they'll droop sometimes (strain dependent).

If you're ordering from Amazon, just get some fine dolomite lime. Espoma lime will bump that PH back up in a hurry. I just top dress the pot with some. No need to go overboard. I used ~1-2 table spoons per 3 gal pot when I encountered a similar situation. Worked almost immediately...

I like to run MH and HPS in veg. I change the bulb depending on my needs and/or the needs of the plant. If/when they make affordable LEDs with adjustable spectrums, I may jump on board.

Looks like over fert to me too. Are you using a bloom booster with really high PK #s.

Beneficial's didn't help me. As a matter of fact, I'd say they made it worse. Switch to hand watering soil or some other media or a drain to waste system where the water reservoir is depleted in 2-3 days.

I also abandoned hydro because I could not defeat the dreaded slim. I even replaced everything including cleaning tools and it still came back. I think it's in the water. I was conducting experiments to try and isolate the problem and ran plain water in a reservoir with h2o2 and it showed up...

Tiniest bit over fed. I'd probably go plain water next feed and then 50-80% nutes on future feeds.

I'd say genetic/mutation, it'll probably snap out of it...

Now I want to try air pots....

I'd reuse that one. Personally I find fabric pots to be messy and I never really saw any gains vs plastic.
