So here it is. These girls are 24 days into flowering. They are in a 4x8 grow tent with 2 sf4000 spider farmer led’s 20-24” above canopy. I am using organic soil using recharge 1 time a week. My water is PH to 6.1-6.3 and my temps when running is 74 degrees. At night it gets down to about 64-66 degrees. I am using CO2 at 700 ppm. I water every 2-3 days. The pictures below are 2 different plants. Showing I believe 2 different problems. I really need some help figuring this out.E9FC038A-9F1D-43D1-9E01-57A8827C8542.jpegBF1FE1AD-EBD0-4BBD-AFD2-31CD73E91186.jpeg6AC2246C-D653-485D-9B5D-1C3339764A51.jpeg5A7D15D5-F5F3-4DEA-8793-048043D0B416.jpeg80BC5AC0-99BE-45D9-9641-287FE8A3E322.jpeg

You're watering on a schedule. Plants In soil do not need watering on a schedule, they need watering when the soil is dry. Get a moisture meter for $15 and don't water u til it says so.

Your temp seem to be quite low for LED and CO2. Pic 3 is familiar to Mg deficiency and pic 5 shows some signs of cold temp. I would rise the temp, there is nice thread running right now about this topic by @Wizzlebiz maybe he can help... another thing is that the light can be just too strong and causing issues as well. Do not know about organics but pHing to 6,1-6,3 also sounds on a low side...

What PH would you recommend? I have raised the temp up. Thank you for responding

Temps are low for LED grow. Low 80s for flower is what seems to be recommended.

Where exactly are you growing this. Is it a seal room?

PH is low. 6.2-6.8 is the range. Try to go up and down that range with feedings. Meaning feed at a 6.2 and next time 6.5 next time 6.8 then back to 6.2.

Different pH values allow different uptake rates of different nutes.

He is running organics BTW. I think people underestimate the value of temp in rhizosphere as well, not sure but bio should be kept warm...

Yea thats beyond my realm of understanding unfortunately. I dont grow organic. I planned on trying but immediately it went south lmao.

I am back to nuking my plants with synthetics.

With that said its important to keep root zone temps good as well. Its not just the canopy we should be looking at imo.

This is in a 4x8 tent inside. I will definitely try the range. Thanks for the input

This is my first time with organic soil. Up until a week and a half ago it has been the best results I have ever had.

The same here, promix with synth, “the biggest music for the smallest effort” IMo.
