1200-1300 ppm - i've heard varying values on "max" ... if your vpd, light and fertilizer are not dialed in to match it, it won't matter -- it won't be fully utilized is the better way to say it. Further off that stuff is, the less effectively it can use all that extra Carbon.
think bugby has some video on it?

How long until harvest?Hi. I changed the light cycle at 01.12.2023. So it comes to nearly 60 days of flowering now. How long should I wait until harvest? They look pretty good for me but maybe could grow more yield. The strains are (from left above) Pineapple Chunk, Gelato, Mazar Extra and Sensi Skunk.

BioThrive Fertilizer Water pH & PPMI tested my BioThrive Bloom+CaMg fert water for the first time ever today; I've been feeding 4.5 pH & 340 ppm fert water solution; Soil pH is 6.7-ish per the Rapitest meter. Should I add pH up solution to make the fert water 6.2pH? What if the soil pH increases over 6.7?

How close to harvest?This is my fourth grow and every time I'm doubting myself when I should chop her down.Can I get your opinions? All microscopic pics are on the buds and not the sugar leaves. To me it looks like I'm close, about a week? If I'm off a lot in my time can you explain why? Many thanks!

Soil pH not adjusting even after watering pH water.So Far I've been 6.5-7 pH water, & organic ferts BioThrive Grow, Bloom & CalMag. The soil pH doesn't seen to go any below 6.5; even though I've been feeding 5 pH water to make it lower. Why is this happening? What to do? Does organics in the soil auto-adjust the pH all by itself

When to lower light intensity?When is the right time to lower light intensity? I'm on 5th week of flowering, should I keep my lights on max or reduce the power/increase the distance to plants? I have around 1000W of Led's at 35-60cm distance from the tops. I see no burning/bleaching or anything like that.

Estimating wet bud weight from dry bud weightThe harvest report for the diary asks for wet bud weight, which I didn't measure. (I think it'd be hard to provide that number if you didn't wet trim, right?) So, what's a good conversion: using dry trim weight to estimate wet trim weight?
