Hey az, I'd recommend going with a weaker dosage with every watering.
Thanks, I've been using 1/2 tsp and things are
much better. I can't believe how much time I spent fighting what I thought was an acidic soil. But, I learned a lot. I never thought it was overfeeding because when I used GH I got immediate burnt leaf tips when I fed too strong. Since I wasn't seeing that, I assumed I was feeding an appropriate amount. I didn't realize other (less synthetic?) cause different problems. Makes me suspicious of assertions all nutrient NPK is the same.
I'm also taking this feeling of a "reset" to back away from high PK in flower. I'm mixing equal parts of Sea Grow Flower and All Purpose Veg to get NPK 10-21-21 (1-2.1-2.1 ratio). That's between common recommendations of 1-3-2 and a PK ratio of 1-2 (sometimes recommended because it's what Advanced Nutrients does.).
I'm going to try this before experimenting with higher PK (booster) strengths. Next test will be to try Sea Grow Flower & Bloom (1-6.5-6.5 ratio) in late flower. Then earlier in flower. I can also experiment with Hawaiian Bud and Bloom (1-10-3.4 ratio) to bump up the PK ratio toward 3-2.
So many people say boosters aren't necessary. This seems like a good time to start fresh and see the difference myself. I don't think I would have considered this if I hadn't struggled with acidic soil (overfeeding) so long. Got me to thinking how just because it says "Flower Bloom" on the label doesn't mean it's the best ratio for flower. When I saw the 50/50 mix landed between two commonly advocated ratios, it was another lightbulb turning on in my head (along with the overfeeding lightbulb).
I'm finishing up an autoflower and four photosensitives that struggled with acidic soil (and my remedies) using 1-2.1-2.1. I'll probably use a booster on them at the end. But, I have an autoflower seedling that I've started at 1-2.1-2.1. I'm looking forward to seeing how this one turns out.
Also water with pure ph'd water once a week.
What is the purpose of water-only feeding. Someone (mick941?) said it helps the beneficial microbes in the soil rebound, consume residual nutes that could become detrimental salt buildup? But, I don't understand feeding slightly less nutes all the time wouldn't be the same thing?
For example, I water every 2 days. Once a week water only will be feed-feed-water. So, instead of feeding 1 tsp per week in that on-on-off fashion, why not feed 1/3 tsp every feeding? It's the same amount of nutrients each week.
If the nutes are detrimental to beneficial bacteria, there'd be a third less harm to the soil all the time.
I'm just trying to understand why water-only is preferable. However, sometime I'd like to try a teaspoon once a week, or a tablespoon twice a month. I know some people who'd like to grow weed with the ease of a houseplant. I'm curious how Grow More Sea Grow would work with infrequent feedings. Seems overfeeding doesn't hurt the plant. Stuff sits in the soil waiting to be used. I'm going to try it sometime soon.
