Feedback on my first plant

Leofsstarted grow question 4mo ago

Hey guys! Can you all give me a feedback on my plant health/setup? (First grow) It’s an American Cookies Strain on a 80x80 setup. Been feeding it with PH regulated water with nutrients, keeping the temperature around 26c with 70% humidity. Is it time to already top it? As in lst

Salam Leofs! 👋 Welcome to the brotherhood of growers! For a first run, you are doing great. 🌿 Let's break down your "Modern Engineering" plan here: 🛠️ Topping vs. LST: Just to clarify, these are two different tools! Topping: Cutting the main tip off ✂️. This splits the main energy into two new branches. If your plant has 4-5 nodes (pairs of leaves), yes, you can top her now! LST (Low Stress Training): Bending the branches down to expose the middle to light. You can do this with topping or instead of topping. Hungry Girl: I agree with @Green_claws. If she is looking a bit lime green/pale, she is asking for more Nitrogen (Grow Nutrients). 🍽️ Don't be afraid to feed her! Environment: 26°C / 70% RH is a perfect "VPD" sweet spot for vegetative growth. She loves that humidity right now. 💧 My advice? Top her once (snip the very top), wait 3 days for her to recover, and then start bending (LST) the side branches. That’s how you get a bush instead of a Christmas tree! 🌳 Happy Growing! 💚

P.s keeping your rh at 70 is great for lights on, but if you are ignoring it at night, with the 10F temp drop from lights off that 70% becomes 80% almost instantly, at night cellular respiration occurs, plant spits out water all night. Stomata will close entirely above 75 without light, zero gas exchange will occur, zero evaporation, anyone who religiously follows daytime VPD must make sure when growing indoors that there is a sufficient dry cycle incorporated into your grow, or the moisture will slowly build over time. Once a medium becomes saturated above a point oxygen modes 320,000 times slower causing what appears as oxygen lockout.

Nitrogen in of itself would not cause the interveinal chlorosis as it is. It would be far more even and work its way from tips inward. Would be more plain chlorosis than interveinal. Red, purple, or blueish stems and are a classic indicator that a plant is struggling to uptake or is demanding more P. However, the reason for this deficiency is rarely just a lack of P in the soil; it is often a lockout caused by environmental issues, with lack of oxygen being a major culprit. Once oxygen supply becomes scarce in a medium mass flow will slow dramatically. Calcium (Ca) and magnesium (Mg) are primarily taken up by plants via mass flow. Phosphorus is unique in that it can bind with different elements depending on whether conditions are acidic or alkaline. In alkaline pH7.0+ soils, phosphorus binding shifts to Calcium and Magnesium There may or may not a be a direct deficiency, but looks more like a combination of things going on. Gluck.
