Why are my leaves so droopy and I’m getting some discoloration. I’m using a light meter and setting my light to the recommended setting for the particular week. I am watering twice a week and I am using Jack’s 321, silica, Regen, and fish shit. I’m also using reverse osmosis water. I’m not sure if I’m getting a Calcium deficiency or I’m under watering
What size pots are they in, and what kind of soil? Twice a week sounds pretty stingy on feeding/watering. Without knowing more about your particulars, I’d say they should probably be thirsty around every other day.
Typically, with a pure water source it’s advisable to add some calmag to your feedings. The more details you can give us about your grow, the more the community will be able to help you.
4 gallon pots and the two on the right are in cost of Maine Stonington blend soil and the two on the left are in a mix of fox farm ocean forest and Happy Frog with strawberry fields at the bottom.
I have well water that is hard so I figured the reverse osmosis water would be good. My outdoor plants did fantastic this year with my well water so maybe I’m overthinking things. I think I’m going to go back to using well water and water a little more often. Just not sure how often to use the Jack’s 321
I’m unfamiliar with Jacks, I use Advanced Nutrients, but there’s tons of Jacks users here that will come by and help out.
R/O water is excellent for growing, you might want to consider not switching back to tap water, or maybe use 75 to 80% R/O and add 20 to 25% tap water to it as a buffer. Depending on the specifics with your water, that might eliminate the need to add calmag.
Second the advice to mix back some tap with your R/O!
Id def check your ph. Do a slurry test. 2parts soil 1 part distilled water. Stir allow to settle… stir again… wait 15 min and check your ph and ppms.
I use jacks 321 in coco. You said you were using silica. Are you adding it first? If not, add the silica first and allow it to sit mins or so. Then do the Jacks mix in order. PH the water and then add Fishsh!t or any microbes last. I wouldn’t feed until your ppms in runoff are around 1000. To me they look like a PH issue, the soil should have plenty of nutrients left, but not sure, so test your runoff ppms.
I do it in that exact order. And my pH is always adjusted to 6.5. I really think I’m under watering as this morning they looked a little better. Still not sure what the brown spots on the leaves are from though
It could be a deficiency, are you feeding them now and if so, what is your ppm at runoff? You’re using Jacks, so no need for calmag. Calcium deficiency can casue spots, but so can Magnesium and phosphorus. Are you using the recommended feeding dosage from Jack’s? It all begins with getting a ppm measurement from the runoff. Do that and we’ll go from there.
