It’s been a while since I posted. Just thought I’d share.

Indeed you did. I think we all learned that lesson at one point or another. Those fertilizer charts are developed using optimum perfect growing conditions with maximum lighting and then the sales and marketing department add 30% to boost sales. You really should get an EC and pH meter. It will...

Burnt and nutrient lock out! Post some pics under natural light. Just to clarify, you’re giving a Tablespoon (Tbsp) of Grow, a Tbsp of micros, a Tbsp of Bloom, and a Tbsp of Tigerbloom And a Tbsp of Calmagic? What is the EC of the fertilizer solution? I’m guessing 3 plus. According to my...

I’d guess thrip too, as jjgrow420 said.

Start by bringing your temperature up to 78-80. They look like then need fertilizer. My experience with FFOF soil is it runs out of pH buffer around week 7-8 and then the pH drops off a cliff. With FFOF you can get away without pHing your fert solution early on but it’s not good practice...

Roger that. Thanks, appreciate the input.

Rather than daily inputs, you might want to consider using a WiFi temp and rh data recorder. There are a lot of them out there that download to any device. I use SensorPush

I was just reading the Seedmans blog about making and using lactobacillus to increase terpenes. Has anyone tried this? https://blog.seedsman.com/improve-terpene-production-with-this-recipe/

There is a separate VPD chart for flower and bloom. Are you using the bloom chart. Mine bloom chart shows 1.5-1.6 VPD for 78F and 44%rh. Just at the edge of the acceptable green zone. fYI my chart is set for 1.5 degrees F for leaf temp differential. LEDs.

What are your temperatures?

I use a 12/12 schedule and add far red light end of day (EOD) for 5 minutes pre and post lights out to jump start the sleep cycle. In my experience, 12/12 with far red EOD is shortening the flowering cycle at the expense of some yield. For typical 9-10 week strains probably not worth the yield...

If you’re going to go by trichome color you have to check the ones on the calyxs not the sugar leaves. And so you have to wait for them to swell up in order to check them. She is going to put on a lot more weight in the next 2-3 weeks.

You need around 30-35 actual watt of high quality LEDs per square foot for flowering. So that light should be good for flowering 10-12 square feet.

Roll it up in baggy and drop in random places, play grounds, school yards, park benches.
