Hi guys!!
As suggested i'm starting now my digital diary. I'm at the moment at Day 42 since I inserted the seed into the Jiffy to germinate.
Medium:
Hydro (DWC)
Size of Grow Area and number of plants:
0,6 x 0,6 x 1,6 M grow tent(ProBox Classic) with one plant
Lighting:
150W HPS
Extraction:
100mm Extractor by Garden Highpro (107m3/h) on top of the tent and a 15W fan on the bottom bring air from the outside to the inside of the tent.
Normally I let the door of the tent open when the lights are on to prevent high temperatures inside the tent. Normally w/ lights on and door closed the temperatures reach 32ºC. I don't know if it's normal or if it's ok to leave the tent open.
Pot Sizes:
25L
Nutrients:
Try-pack Indoor by BioBizz
Mills CalMag
Vitalink pH Up/Down Easy 25% Essentials
Other Equipment:
PH meter - Milwaukee PH600AQ Digital pH Pen
EC meter - Milwaukee CD611 Digital Conductivity Pen
Air Pump - Marina 100 (85L/h)
2 Air Stones (10+15cm)
Plan for the grow:
I already done 2 rounds of topping (1st round - 1, 2nd round - 8), one week after the 1st round of topping I started doing some LST and preparing everything to do SCROG. Already mounted an adjustable wire net 20/30cm above the top of the pot w/ 7cm2 squares.
As I mentioned on the post about nutrient deficiencies, I'm having a problem at the moment w/ my baby.
Apparently was Magnesium Deficiency so I bought Mills CalMag and added 5ml to the reservoir. The EC before was 0,6mS/cm2 and after inserting the CalMag and 2ml of BioGrow raised to 1mS/cm2. Don't know if was a too big gap between levels. Don't know as well if I inserted enough CalMag. I believe I have approximately 12L of water inside of the reservoir.
Great start to the diary!
Get some pics up of the problem youre having so we can see it. Then we can try and diagnose it and get you back on track

I've posted as well photos of the topping and fimming that I've done and as well of the roots so you can tell me if it's everything ok w/ them and if they are normal.
Thank you guys.
I've never done DWC and only on my 3rd grow, hope you sort it out soon. In the same size tent though!
Macky should short you out or someone on here should know.
I use a chart that is like a poster with lots of pics of different leaves with deficiencies, I pulled 2 off the net which may be useful? I keep it in my phones note pad.
Also Macky's pictures are really useful on this website. Very easily understood and they give you lots of information at a glance keep it in my phones not pad.
@diy-rik Thank you man.
I have one picture like that as well. But sometimes is hard to figure it out alone, w/ no pro help.
@bs_monteiro @greenbeard had a good chart for EC I think. Maybe he can help ya out with it too🙂
I want to ask you as well a EC/Feed Chart as well. Now I'm guiding from this one but I dunno if this is the best one.
Thank you once again.

They always look happier together lol. Looking good man, nice work mate
@macky Thank you very much man. Oh and btw, can you help me with the EC/Feed chart, if it's the most adequate or not and can you tell me if the root system is normal like this on?

Ph marks still showing, keep diligent on that ph level BS, it’s super important to control that in any hydro situation. Keep it up and this lady will reward you with her sticky bounty before you know it mate.
@monkeydo What are the pH marks? Normally the maximum that the level reaches is 6,2/6,3 and then I lower it to 5,7/5,8. Do you think is that too much?
@bs_monteiro those light streaks on those leaves look to be ph stress, at least to my eye. They show up when the plant experiences rapid swings in ph mate. If you can narrow the ph reading window some that would help. I grow in coco so it’s a form of hydro like dwc and ph stress can show up there too very easily. Plants thrive on consistency. While a small ph drift is normal and even healthy for the plant it should not drift quickly or be allowed to drift to far. The ph scale is logarithmic, meaning going from 6.5 to 5.5, the solution is 10 times more acidic. That’s a lot for a plant to handle if it changes quickly and our plants let us know when something is bothering them if you know the signs to look for. If you can narrow that swing your plant will appreciate it. It does not look like she is in immediate danger mate so don’t panic. Quite the opposite, you’re learning fast and doing well. Consistently is key in growing high quality Cannabis and that’s what we like to grow at Percy’s. The best weed we can get anywhere is homegrown 😉
@monkeydo wow!! Thank you very much mate. Very inspiring!! I will be more aware of that. 😉

@bs_monteiro looks good so far man. Always loved hydro.....maybe one day I'll try it
@colacody Yeah I'm loving it! Much better than soil, in my opinion, and I think in certain way it's easier to control everything.
