See i thought it was magnesium but usually magnesium affects the older fan leaves, not usually the new growth, but then again if it is magnesium they had to have been in a deficiency for a while for it to get this bad!Magnesium deficiency View attachment 939828View attachment 939829
I have been feeding every 2 days or so with liquid seaweed, URB, and molasses I was trying to copy cali green a method of an organic grow. Will that not supply enough nutrients for my plant?so, the question is - what (and its frequency) are you feeding it with?
I am using a mixture of fox farm potting would and Malibu compost. For watering I’m using RO water. I recently bought Cal Mag to add to my plants diet. Do you have any recommendations for other nutrients?I think you need to supplement your soil with a small dose of a general fertilizer. It looks Nitrogen deficient in the new growth, althogh N deficiencies usually affect the lower leaves first. Organic soil is great but doesn't always work out... without things being broken down in the soil, the plant doesn't get the nutrition it needs. A 25% dose of a 20-20-20 fertilizer (like Jacks) will quickly show improvement if a deficiency is the cause, if not, the small dose won't really cause any more problems.
What kind of soil are you using? Are you using regular or RO water? There are a few variables that can cause problems, but I think it is just a case of needing a more balanced diet. Seaweedis great but not as a source of major nutrients.
Thank You for the last couple sentences. I never water to run off. However I do feed than water to prevent build up!!!My two cents is that you overwatered the yellowing plant. You don’t need cal-mag in soil. I’m not sure what URB is but your plan seems solid. The oven forest is good stuff and if you are in big enough containers it can take you right through a grow. Chasing deficiencies is for hydro growers. With soil the plants take what they need. However, root damage caused by overwatering can “lock out” nutrients causing them to appear like they have a deficiency. Make sure you are watering judiciously. You’ll read people recommending to “water to 20% runoff. That’s a hydro thing too. Soil should be kept moist but not saturated.
Sure. I have found since joining this forum that at least 90% of problems in soil cone from over watering or over feeding. And I have found that many people are confused about the style of growing that they are attempting. Soil and hydro have very little in common with one another. And good advice for one can be fatal to the other. Good luck I’m sure with care she’ll straighten herself out.Thank You for the last couple sentences. I never water to run off.

Agree about how many issues involve these 2 items.Sure. I have found since joining this forum that at least 90% of problems in soil cone from over watering or over feeding.

I water about a half gallon per plant would that be too much? My pots are about 7-10 gallonsMy two cents is that you overwatered the yellowing plant. You don’t need cal-mag in soil.

well. Maybe maybe not. You want the soil to be moist but not saturated. Somebody here posted today really good watering advice for plants in pots. I would think more like a pint a day average but who knows. You have to be able to tell what your plant is taking up. A lot of people use the “heft” method: learn the weight of your potted plant when it is watered and when it is dry and use this to gauge how much water it needs. its Not an exact science. Water less but do it more often. Is another bit of advice I’ve heard. You’re not looking for runoff. You are looking for things to dry out a bit before watering again.I water about a half gallon per plant would that be too much? My pots are about 7-10 gallons
Fox farms products are kind of hot right out of the bag, and combining it with compost won't cool it off any. I use tap water for my calcium ad magnesium... it isn't terribly hard, around 225 or so, I think. With the soil you have and compost, I would think you have plenty of nutrients to last you for a while. I use Promix, which is buffered to offset the natural acidity of most nutrients as well as the peat that is used to make it. It drains great but is lacking in most nutrients. Fox Farms is ready to go, but might be susceptible to a pPh swing unless it is buffered. Check your Ph... I like to keep mine at 6.5 to 6.7 in Promix, watering daily. I only feed about every 12-15 days when growing max.I am using a mixture of fox farm potting would and Malibu compost. For watering I’m using RO water.
