Lighting MedGrower does HS1 grow - Mazar (Photosensitive / DWC)

[HolyTHC]

Great bro, now your babies look good Keep it this way
You now see for yourself, bright spot on the wall now is reflecting many light Good job on these walls too
I would consider to plan some more light for flowering - maybe another HS1 This would probably double your output on same time spent

Thanks bro! Yeah it took a little more effort to install that than I first thought; a lot of measuring and taping. Also had to uninstall and reinstall the hooks to the walls. Did drill two options to hang the net to, 65cm and 80cm heights. Ofcourse the res itself is around at 30cm height already.. Any advice on which one should I choose or should I show the wall some more drill?

I did mention in the very beginning that I am going to add another HS1 for the flowering, in about 2 weeks from now. Both of these are with 80x80 diffusers, current one is HS1.1. version with holes on the top and the other one is the orginal version without the holes. Damn the new version feels much more cooler from the top when you touch it BTW.

Another question I have is that I went and got CANNA Mono MgO 7% and CANNA Mono Ca 15% for the future feeds. I have no idea how much of those should I really use and on what ratio? I bet people have a lot of experience with that product --> Any advice? Or are the instruction valid?

It's too early to worry about net. Let them grow, veg them, LST them and do whatever you wish, and when time comes, you will know what to do.
MgO i would recommend to use in foliar spray. Make very weak mix with distilled water and give your plants foliar shower before sleep (before darkness) 2-3 times a week till flowering begins.
Also you may not need to add these additives to your nutes at all. These only should be used if plant shows Mg or Ca deficiencies. For example, i'm using tap water, which already have plenty of Ca and Mg, so i even do not have these additives, never needed it. You may have it for a case of emergency, but do not introduce them till needed.
I got HS1 version 1 without holes on top and i instantly took top lid off. After full grow cycle i decided to use really big radiators for better cooling, as this factor is more important to me than compactness. Now that radiator is more than 4x of original size and is barely warm, i'd say body temperature. Also this way i completely eliminated noise from lights, now my box is totally noiseless except air bubbles in DWC But this is only my way, you absolutely do not need to d something with your HS1, it is working well as it is
All this is only my IMHO and NOT the instructions of any kind. Do your research before taking any steps!

DAY 15

Girls are doing alright by the looks of it and gaining more healthy green colour. Both showing a little purple on the stem of the fan leaves, I take it as a genetic thing for now since it seems pretty common.

One thing that I knew to expect happened though. This morning the pH had dramaticly fallen to 5.2 from the set 6.2 in one day. For some unknown reason this happens to me everytime around this phase of a plants grow. Can anyone give an answer why this happens? Anyway, I corrected the pH back to 6.2. Res was ok, no bad smells, roots fine, a bit of colouring from the nutes but nothing alarming.

Nodes are forming now rapidly and I was thinking of giving it some time still and do topping after 4th node. I would be really teased to try out the technique called Main-Lining (referring to Corgy's post about it; https://www.autoflower.org/index.php?posts/884651/) that I learned about it but I think it might take a whole extra couple of weeks to do properly.. Maybe I just leave it for now to prevent any f*** ups.

I added a new air pump also: Hailea ECO-9610 (10 litres per minute). It has 4 air outlets so I also added couple of new airstones.

pH 6.2 (corrected from crazy low 5.2)
EC 0.7
RH 58
Temperature day/night: 28.7 C / 26.9 C (DIF: 1,8)

Looks like the earlier paleness was due to your pH! Great growing bro.

Thanks for the compliment bro! It is going good thanks to all of you helping me out here. In fact I was happy to see first time having so tight space between nodes. I check and adjust pH everyday so the paleness couldn't have been due to that

looking great she will take off now bro.

Hey guys! Just a quick update on things, I will do a full info along with pictures on weekend but tomorrow is time to give a new feed and I checked pH and EC. pH stays rather stable now at 6.2 but EC has risen to 0.9.

Leaves are still fine but quite dark green in my opinion so taking that and the risen EC I think I will continue with same level of nutes around 0.7 EC. What you guys think? Sorry I dont have change to take pics at the moment... Oh yeah, I have done the topping now also down to the 4th node like I said I would.

HS1 is now about at 30cm distance and it seems to really work good there.

Cheers guys! I get back at it tomorrow with pics!

Sounds good to me bro can't wait to see them.

If you feel that nutes are a little strong - just replace some with water and add replaced part back to tank with feeding other day, when refilling. This way you can play till you find a sweet spot, which is optimal for your plant. You will see that by perfectly green leaves and plant's pose, it keeps its leaves widely open and just under perfect angle to the light, trying to get all the light it can.
Have you tried Mg shower before sleep yet?
