Day 3.5 of flowering! Flushed the res's and changed the nutes to Dyna-Gro Bloom nutes at a ~420PPM and a pH of 5.8. I also switched to the HPS bulb. Here are some pics if anyone cares :mrgreen:.

Here's an update with on the girls. Day 42.5 and Day 1 of flowering. There still seems to be an issue with two of the plants. Still not sure what it is or if its even a big problem! :mrgreen:

@burnin Not sure if there is a water softener hooked up, I'll have to go explore and find out. @burr Will definitely look into getting some drain tubing installed. Also just switched the girls to 12/12 and was wondering, when is the optimum time I should switch the nutes to bloom fertilizer...

Just took some more pictures of the girls and they seem to look fuller and healthier (hopefully). @Burr, do you suggest I should start flowering them in the next few days? I want to make sure they aren't being stressed when I flower them AND to maximize yield in the room I have.

I just added more nutes to the res buckets and now they are all at 400-420PPM. I also added 1 teaspoon of the DM zone per 5 gallon bucket. I will update on how they're doing either tonight or tomorrow with pics. :mrgreen:

@burrr Do you mean at the 320ppm level or 150ppm level? The inline fan that is connected to the 600W HPS hood is drawing in air directly from INSIDE the tent. I originally had it drawing air from outside the tent but had to switch it because it was the only way to keep the temps 15 deg cooler...

I'm flushing every week to 1.5 weeks. The nutes are Dyna-gro grow and the only additives as of now are pH up and down. I'm waiting on the Dutch Master Gold Zone to arrive (hopefully tomorrow). Here's the link <http://www.dutchmaster.com.au/?language=english&page=product&product=ZONE>. There...

I would like to make this thread my grow journal for this grow so if the Mods could move it to the right area, I'd appreciate it. As for the girls, I've ran into some problems...again. I can't figure out if they are being over-fertilized or they are nutrient deficient this time. They have...

Here are pics I took half an hour ago. As you can see they are finally doing better a the roots are finally starting to protrude through the net pots. I have been top feeding them once a day with water with ~160ppm of nutes at a pH of 5.8. I will start feeding them 2x a day, today, until they...

Nutes should arrive tomorrow, will feed them and update with more pics. Thanks!

The rockwool is staying moist without me watering them at all. With that in mind, should I water them with pHd water with no nutes or with nutes at 150ppm?

So far I have flushed the RW twice (today and two days ago) with distilled and pHd water. The ambient air temperature is hovering around 77 deg F. and I'm still waiting on my res thermometer to arrive. @forget, I will do a full flush when my nutes arrive with my thermometer. I JUST ran out...

I went to Home depot, Walmart, and Petsmart to look for a thermometer to check the res temps but they were either broken, cheap plastic for aquariums, or didn't have them. Will probably have to order one online. I also purchased some air tubing to get the air pumps out of the tent and to suck...

Thanks for the info, I JUST dropped the water level down below them.

@mike The conversion factor is 0.5 (from http://www.tdsmeter.com/products/tdsez.html) so the EC is 180? (360ppm x 0.5). I added the Epsom salt because I thought it was a sulfate and/or mg deficiency from the research I was doing :?. I will check tomorrow to see if I can find a cheap window...

Firstly, thanks everyone for your input. @mike, I don't have an EC meter unfortunately, only TDS and pH . I just finished diluting and lowering the water level in all buckets. They are now ~1 inch below the net pots and about 360PPM. This includes superthrive and the Epsom salt I'm assuming...

thanks for the input guys, going to drop the pH to 5.8. Here's the link to my other thread if you guys are bored https://www.rollitup.org/marijuana-plant-problems/502700-you-wont-solve-my-600w.html#post6926648

Here is the setup of my FIRST DWC grow: 600W HPS light. Five, 5 gallon buckets. 2 SDA530 air pumps with air stones (1 supplying two buckets, the other supplying three) Humidity fluctuates from 25%-45% Temperature fluctuates from 79-90 F All started from feminized seeds 18.5 days ago...

I've been looking all over this site and the web for answers (for the past couple days) and can't find a solution. I'm using Dyna Grow "grow" with attached feeding chart and it says to have a pH of 6.5-7. I thought that was a little high for a bubbler setup so I've been keeping my pH to...

Are these ready? Growing under 400HPS light.
