I use my high 7 ph tap water without altering it. I don’t have any problems. I used to believe I got away with this because of low ppm tap water but I recently trashed my ppm meter for giving me crazy readings. So I’m less sure now but still getting away with it so whatever. Good news is that jacks at full strength might leave your pH in a good place. Takes me from high 7 to mid 6. I use liquid fish tank drops to test mine. Had a ph meter once upon a time as well but that also found its way to the trash.
I have a hunch you could just use your tap unaltered up until feeding and then ph should be okay with fert. Added. If you have issues you may need to get some ph down and treat before watering.
i had read that in most cases tap water would actually be better than treated/filtered water cuz of some of the minerals so had planned on just using that. So the final answer as far as feeding is wait the 3-4 weeks right? These are supposed to be ready to harvest in 8 weeks (autoflower)…and does it matter if i just leave the lights on or should i do the 16on/8off?
I would run 24-0 for the first week or two at least. Then you can back down to 20-4 or 18-6 for the rest of veg. Then a lot of people flower them under 1212 but a lot of people also just stay 20-4 or 18-6 for flower. Both viable options. I wouldn’t run 24-0 for whole cycle. You could being they are autos, but I haven’t seen a happy plant that gets no rest ever.
Yes dont feed right away. Autos are extra sensitive to nutrients. Feed when the cotes start to yellow.
Yw. You want as much light as she can take and still give you the node spacing you are looking for. Seedlings don’t want much light at all. Vegging plants don’t need a lot either. They are light whores in flower. So basically you adjust lighting based on how the plant is growing. If you want short plants with tight nodes you hammer em with light. If you want more stretch you give less light.
If your nodes are super long shes asking for more light.
I don’t get into the whole…okay my plants are at week 5 so they 18000 lux for 18 hours to hit DLI bla bla bla. I just read my plants. Too short I raise light. Too tall I lower it.
Light green she’s hungry. Dark green and waxy she’s full.
I’m simplifying it. But if you read some journals around here there are a lot of number guys. That’s not my style.
So to your questions, it depends when you want or need both switches on. Not until after seedling stage would be my best arbitrary suggestion.
To me it would be parts A and B…and maybe the clone stuff too cuz it says for new seedlings and root development. Each one says the amount to use per gallon but i obviously don’t need gallons of water for these 2 plants so would i make up a couple gallons with the nute measurements and use it periodically or divide up the measurements and just make a gallon?
