heavy leaves

Is each segment of affected leaves a bit curved? Reused and leached out growing media? If so a possible zinc deficiency, but that’s kinda rare. Just my best guess, Good luck!

thanks for the advice guys 💪

Bruce bugbee has lecture grade videos on the 9 cardinal rules of growth, they are free and priceless in value if you seek to grow. 90% of all indoor cannabis problems are environmental. We don't grow shit.....the code written within the DNA provides the blueprint, nature does the rest. All we really do is provide optimal enviornmental conditions for growth. Good luck !

If your making 65rh in veg going to be 80 in flower.

Alternatively keep humidity below 50 if you can if you want to play safe. Providing high rh is great as it allow the plant to absorb more moisture from the air but this means less water from rootzones. Anything over 65rh and the air will become so heavy the plant will start to close its stomata (lungs) in order to prevent drowning essentially. No perspiration = no photosynthesis. Also to take note the rh at top of a grow can be 20-30rh higher. Measure everywhere.

Your VPD is 1.25-1.5 range... depending on what chart you look at that is either fine or slightly high for later stages. Your RH% would be better off below 60% or even near 45-50% to help reduce microbial risks, but you'd also want to reduce temperatures a bit too. VPD is relative, and would be similar at cooler temps with lower RH. It's a fancy way to understand the rate at which the plant will uptake water, assuming it is healthy and happy. ("transpiration" not perspiration, but close enough) It's pretty hard to give a specific answer to the issues with the plant, given the info here. First, I'd stick to a more consistent practice when irrigating. Water fully.. entire pot should be wet. 10% or more runoff (waste) for soilles and limited runoff with soil. Wait for pot to reach a particular weight -- the safest to start is when the top 1" is dry. Learn the weight at that point and it'll be roughly the same volume of water required. Don't try to pick a volume. Let this process dictate. Then, water to appropriate runoff. Soilless has fertilizer iin every irrigation. Soil is more often fertilized every other or every third irrigation. The concentration you give is the primary factor here. Because of how you have irrigated lated, that adds a wrinkle in diagnosing any leaf symptoms too. pH can cause any and all problems, so make sure that is in check first. Starting at tips like that could be potassium deficiency. The heaving clawing is usually a sign of toxicity, but could also be due to recent watering habits if you've been watering too frequently. If soilless, i'd suggest a simple 1.3-1.5EC mix and follow the above irrigation procedure for soilless. Ship should right itself. React to anything crazy, but get it on a consistent feed for 7-10 days and see how it goes befoer reacting too much. If soil, it's a bit more cat and mouse. Consider what you have added or not added lately and general progression of plant. That will usually point in the proper direction. I can tell you calcium nor magnesium (these are 2 mutually exclusive necessary nutrients) fix the leaf symptoms shown in these pictures. In fact, high levels of calsium or magnesium can lock out other nutes. This is where knowing what you have added helps. There is no silver bullet. You just want to find a happy mix that works well and consistently, then play mad scientist when you have a good baseline. Find a leaf symptom chart with an image search... as you see symptoms, study it. It will speed up process of learning.

P.s. as a general rule of thumb rh over 50 things get wetter. Rh under 50 thing dry.

or are they not getting enough light? do I try to bring the lamp closer?
