It looks like it doesn’t matter where the ph range 5.5 to 6.1 is because you would always be locking out something, Is this correct? Or set to 5.5 and let it drift to 6.1? I’m a little confused

I will make a fresh res then with 222, I have probably shocked my plants jumping straight to bloom amounts I have heard if you follow the directions it’s too hot? People usually half? And thanks for the advice this is the first I’ve heard about 2 2 2.

Rockwool cubes, I ph down after adding nutes to 5.6, in veg I used 4 parts grow, 2 parts micro, 1 part bloom at various ppm though veg it worked well In flower week 1 (on day 6 now) I do 3 parts bloom, 2 parts micro, 1 part grow till I reach 900 ppm I added 200mg calmag a few hours ago so now at...

I added some a few hours ago to see if it will help, I was told Flora 3 part had enough cal mag in it so I didn’t use my cal mag incase I burned the plants but had it on standby, Thanks for your reply

Hey guys, I hope you are all well, I have started to get yellowing starting from the bottom up, this is my first grow and I’m in week 1 in flower, Please have a look at the photos and tell me what you think, thank you

I’m curious too, will you be posting results soon?

Ok I will take all this in mind, thanks for taking time out of your day to help it is appreciated Bye for now

I have read the Rockwool sits on a spreader mat, I didn’t find out till recently that an nft table is supposed to have drainage channels, I made my own nft table that doesn’t have drainage channels I should of thought that this should of been a factor in my problems instead of being a noob, I...

It is rw on a spreader mat I would have to raise the rw under the spreader mat as I wouldn’t be able to separate the rw and spreader as the roots attach the 2 If that makes sense? And I will always check my Rez temps from now on Thanks for the advice it is appreciated.

Ok I will follow your advice, is there any way I can raise the rw cubes? Would this help? Is never thought that water temp was important, I’m learning though, it has always felt cold to the touch. I will order Hydroguard now, I also have hydrogen peroxide on the way to help with flushes.

I’m running LED cobs 12 35w running at 700ma right now, when the plants are bigger I will turn on the rest of the lights (24 altogether) and turn them up to 1.4a They may be a little close at 10 inches above the plants but I was told that LEDs can be close as long as it doesn’t bleach the...

Yes I soaked the Rockwool first in 5.5 ph for 24 hours, did they need to soak longer? Would syringing 5.5 water into the rw be a good idea? I mean like squirting a few syringes full of 5.5 water on to each rw cube to flush them?

Oh I see, I set my res at 5.5 and when it rises to 6.4 I will lower the ph again usually once every 2 days

Sorry I don’t understand change the Rez and clear it? You mean change the Rez and flush then clear that water away then add new water? Also isn’t 200 ppm a little low? Or is this temporary? Ph is 5.5 never stand there? I am just a little confused with what you are saying. Thanks

I have air stones running 24 hours, I will turn them up a bit to see if it helps, thanks

Yes I put the Rockwool in 5.5 ph RO water for 24 hours and changed the water half way through.

60L Rez with air stones, flora 3 part, 800 ppm , I change the Rez weekly, 4 parts grow, 2 parts micro and 1 part bloom till I reach 800 ppm, Should I change the Rez twice a week to see how it goes? I changed it yesterday.

Hello I’m new here, I hope everyone is well, My plants are 5weeks old from seed still in veg, I made my own nft tray and I’m growing in rw on a spreader mat, I put the plants in the tray at 3 weeks old so they had a nice root system ready so they have been in the tray for 2 weeks now. I started...
