GH Calculator - PPM Levels / Add Backs - Autoflowers

To add onto what Chow_13 said as I agree with most of what they are saying. The VPD chart integration would be key if the environment was swaying a lot in temps or RH, but if its not I don't think its going to make all that big of difference. I would also think it would be good to have it broken down into 3 or 2 parts per week. for small and large or small regular and large sized plants in your space. this would help account for the variance in feeding amounts. Or something that would be a live chart and you would input your res/runoff numbers and it would suggest what to do. if you wanted this to be used as a standalone reference for all growers vs yourself. Not everyone is going to have their environment nailed in as tight as you are so the feeding guides will need to be different I think. Could also note if you have a regular sized plant but a super hot room you would want to use the lower or smaller feeding guides as the plant will transpiration more giving its environment. An Ideal chart would be one that you could enter in your temps, RH, light ppfd and other variables and it pumps out data on your optimal feeding schedule. but given the work involved in that I think what you got going on right now is banging. I don't know how much more you can add to it other then feeding levels. It looks fantastic and as any grower will say you cant rely on a feed chart alone, need to listen to your plant and be flexible then adjust to what its needs are and what its showing you. The user @nobodybuds like to calculate his feedings down to the T in elemental values vs compounds. Given that Nitrogen is calculated as its single element in fertilizer ratios and Phosphorous and Potassium are calculated as their compounds based on how they used to measure things with ash. 4-4-4 is not 4-4-4 in elements. I feel if you reached out to them in DM they might be able to help you tweak this into something truly wonderful. They are like minded from my small experience with them. But honestly its already a fully functional working model to me. Good Luck!
