remember to include calmag when you re-introduce nutes...make sure to shake well between adding things and that your ph is right where it needs to be...check it 10times if you have too...:d5::pop::smokeout:
 
was this coco rinsed/soaked with 6.0ph & also given a pre-charge? if not you may want to run the whole 3 times the volume through 3gal pot=9gal water plus 1 gal when you add nutes at half strength. usually I stop when I see the water running clear, but since we trying resolve issues and get yours back on track it might be better to do the whole 9gal it will take some time like a few hours, you not want to run it through to quickly and damage the roots...but once you finish that today, tomorrow the green should really start showing up and plant will just look more healthy and things like that.

Finished this pot. Yep, I rinsed it down to 30 ppm and pre-charged with a full dose of CalMag and light dose of nutrients. It was definitely well-prepped. I've just been testing the GH pH indicator drops against my new meter and, wow, that was the problem. I was providing plenty of CalMag, it just wasn't doing any good because the indicator drops are blue-green at 6 pH when they're supposed to be a bright yellow at 6 pH.

I'm nearly finished with the Forum Stomper, just needs a nutrient recharge now. Do you think I should go ahead and do it with the other three as well, or just start administering properly pH'd nutrients? They don't look nearly as bad, and the newest (replacement Fugue State, 5 days younger than the rest) shows no signs of a calcium problem yet.

I didn't flush the other three pots. They don't seem too bad and the trauma might slow them down more than it's worth. They're already slow enough since they are at least mildly damn-near-everything deficient from the ~6.68 pH food I'd been giving them since Day 1. Indicator drops turned the sample a bright yellow, not at all gold (5.5), and not gold (6.5). It should've turned a dark gold with a hint of blue at that pH. A pure, bright yellow like I got should've been, accounting for a reasonable margin of error, 5.8-6.2. Unbelievable.

Cleaned up the tent and fed all the plants a properly pH'd solution for the first time ever. Hopefully things will improve now. I had the impression the indicator drops were adequate because GWE's guides say they're good enough and that they've used them successfully before. I realize they make their money off Amazon affiliate links, but there's just enough bad information there to sabotage otherwise solid guides. I won't be going back.

Time to turn it around. It might take a few feedings to get the pH back on track, though. I'm not going to test the runoff pH since it wouldn't be an accurate measure and will probably just freak me out. Next time there's an issue I'll get a decent soil meter.
 
You will be alright! Patience and ph are the most important things right now. And a positive attitude, tell those girls how much your love them, they will feel your vibe.
@Unique is a good man and a great grower!

I appreciate his swinging by and you tagging him for me. :grin: I wouldn't be surprised if the plants have had a more positive outlook throughout their starvation than I have had--maybe they should be encouraging me. :p Nah, I'm feeling pretty good about the outlook now. I just hope my mistake has disrupted or delayed the cycle and that they'll vegetate a few days longer than they otherwise would have... According to Mephisto, it's possible. I should know soon--if signs of sexing are late, they'll probably flower late as well. That's how I hope it works, anyway...

There's a saying that the poor tradesman blames his tool. I'm totally blaming my tools (pH indicator drops). A different saying has always made more sense to me: 'use the right tool for the right job'. I should've had a meter from the start.
 
I started with the drops too, money also plays a part! But now you know and will do well moving forward. We are all here to help and share what others shared with us.

What day are you on now?
 
Thanks man. White Crack (the pot where the thermometer/hygrometer is) and the suffering Forum Stomper are on day 15, Sour Crack (the biggest and, according to Mephisto, shortest cycling) is day 13, and Fugue State is day 10. I document the younger ones in my offline log as "SC (-2)" and "FuSt (-5)" to make the offset clear (and yeah, two different "FS" strains, pain in the ass to notate). Fugue State has the best chance of turning out fairly normal I think, but Sour Crack seems really rugged and tolerant. White Crack's calcium woes slowed down a lot when I up'd the CalMag a couple days before I got the pH pen.

In a month I'll probably be wishing their development was stunted even more--the tent is going to be a little packed... Three pots in a triangle next time for sure.

just see how they respond to correct ph, they may show a tad bit of damage to ends of leaves once they start getting correct ph.. but the green will start to darken and they should start thriving with the correct ph.. that makes a huge difference in coco..a couple days on the other's and you'll know if you should do the same with them or not....I think you'll be fine though...:thumbsup::smokeout:

that one you flushed is really gonna take off for you.. your really gonna notice a big difference over the next few days...I think the flush just helped get the ph stable the same day vs over several waterings, I didn't want you loose much veg time I'm certain that flush will put you right back on track... if the other's seem painfully slow or like they not doing much...Everyday there Should be notice-able growth, if your not seeing that then you may want to go ahead and give them a flush also, but you won't need go 3times the volume on them even if you can put 2 ---6.0ph gals through them, then 1gal of nutes at half strength them ones should bounce back the same day...You want to be seeing notice-able growth daily... auto's grow so freaking fast I swear sometimes you can actually see them growing...

BTW, good job on the flush... you won't regret doing that... That plant is really gonna take off for you now.. I'm sure of it.
 
Day 16: Big improvement overnight to all plants. No new calcium damage that I see, and two of them are thickening stems and have some tannish banding. That's two days after I added a second circulation fan and really got the wind whipping. Despite being smaller (but older) than SC, WC has the first obvious 5-tipped leaves among them all.

I also moved the pots as close together as possible and moved the humidifier into a corner. The light is 16" from the tallest plant.

I take pics with a 4100 k CFL, so photos are going to look a little yellower than reality. I need to find a 5500 k I have somewhere around here, or buy a 5000 k...
