[IMG_7263] [IMG_7264] [IMG_7265] [IMG_7266] First-time grower here, looking for feedback – I have two photoperiod plants growing in a 2x4 tent with conditions around 75 F, 70% RH, and .8 VPD on an 18/6 schedule, started in happy frog soil. I’ve been lightly watering every 2-3 days with pH bet…

Welcome my friend! First thing to understand is the soil has enough nutrients pre amendment to last like 4 weeks roughly, you shouldn’t have to add any nutrients to it for about that long, do you have pH,ppm meters? I would suggest only giving her pH water 6.3-6.5 for a week or 2 and see what happ…

Thanks friend! Got it, that makes sense. So no calmag too even if my water is RO? Yeah, I’ve got the Apera PC60, but I’ve only explored measuring pH so far. Thanks for the suggestion. We’ll see if she pulls through.

I’m not sure about ro water, so maybe one of the following can help with that. @Lostgirl , @OGIncognito , @merlin44 @Serf @Storm , @SausageMahoney Hopefully one of them above can help better, again welcome to the forum!

Thanks for the tag @DanB I have never used RO so no help.

[image] RO water pH question Watering Add calmag to your RO to get it up to 250-300 ppm. It then becomes PH stable and can be used to adjust your soil. PH unstable water will become adjusted by the soil instead. Does this help any. Im not RO savvy either. @…

Seems helpful. Thanks! Sounds like I should add calmag and get familiar with measuring ppm.

Yes fo sho. Ppm and pH dialed in will eliminate a lot of issues. Welcome to ILGM. We are all here to learn and help.

My biggest mistake is overwatering. They can tolerate being thirsty better than waterlogged.

150 ppm of cal mag will make your water stable and give an accurate PH reading. You can’t read ph of RO as the meter will jump all around, but the water must have bicarbonate added to it to give a steady PH.
