More research tells me that it is, in fact, heat stress? Can 80' ambient temps really do that?

Anyone got a real answer? My mother in the dwc tub is doing the same thing. Definitely not heat stress as it's a whopping 12" away from the 4 bulb t5 veg light...

As an update, I got super OCD with the PH. 5.8 in, 6.2 out They get fed every 24h with the following schedule Day 1: Nutes Day 2: EWC Tea Day 3: RO Repeat They're looking super super healthy now.

Yeah I think the problem is I was watering the guys that have reached the res and the guys that haven't on the same schedule. Will try the following this week: Guys that haven't hit the res = twice a day Guys that have hit the rest = once a day, feed every other day I'm going to make sure my...

Thanks for the replies guys. What do you fine folks think about a once a day watering, feed every other day? If I go this route, should I still be feeding nutes? The formula mentioned above is approx 50-75% of what it says on the label (per product). Per a different conversation I had...

In 3 days the res would be dry I could get by with 24h

If so do I need to flush or....? These guys are 3 weeks into veg, 16oz hempy cups, 3:1 perlite/verm. Fed twice a day with the following formula (I've been thinking of switching to feed once/water once per day ie every 12 hours) 1/4 tsp superthrive 1/2 tsp calmag 1 tsp sensi-a 1 tsp sensi-b...

maybe, but i'd rather learn from somebody else's mistakes :lol:

No worries, your reply was helpful, thanks.

Anybody have any comments or a link?

Yeah I bet the nute burn is from the leftover MG perlite in my perlite wick cloner... Sorry, can't get a more gangster macro shot from my POS camera

So what is this stuff? I have no other obvious signs of mites and it doesn't look like PM. Didn't notice the problem yesterday so I assume it happened within 24 hours.

AFAIK, you'll be doing that until the roots hits the res, about 7-10 days. Yes, you are not supposed to let the water sit there, that's why a. you water until runoff and b. you flush it every once in a while. Basically, your res can't go dry until the roots hit them.

Been to ALL the big box retailers and have not been able to find any vermiculite AT ALL. Friend says he got his bag (MG probably) from Home Depot but no dice there either. Maybe they don't carry it anymore? Anyway, I know there's alot of prop215/sb420 guys here, so maybe one of you guys...

I did a mix of AN Sensi A+B/Superthrive, now only Sensi A+B Not root rot, this shit. http://www.icmag.com/ic/showthread.php?t=55259

DR120 is spec'd @ 3'11" x 3'11" x 6'7", so about 120 cubic feet 4" CanFanHO is rated @176 CFM, but that seems so low... I'll make a journal when the time comes. Just been playing around with mothers and clones so far, pretty good success with this perlite wick cloner so they'll be ready soon.

Hi guys, just wanted your opinion on this stuff before I buy all this stuff. Planning to grow hempy, 2 weeks veg -> flower, 3 or 5gal pots? Already have a 4 bulb T5 with veg bulbs that I'm going to use for vegging (also for mother plants). About to pick up... Jardin DR120 Cool Sun 6"...

As a followup to this post: https://www.rollitup.org/dwc-bubbleponics/191950-doh-got-algae-my-dwc.html Algae's been pretty dormant for the past 2-3 weeks. LOTS of 3% h2o2 in the water + spraying the roots multiple times a day with h2o2 water. Temps have been pretty good as of late with...

Update, I think most of them will make it. They most certainly don't feel dead (yet) See pics. No intervention on my part, just check the res everyday. Been about 4 days since transplant.

hey man, I'm in the same boat. https://www.rollitup.org/newbie-central/197924-noob-question-re-perlite-wick.html
