sounds very sane to me. for what its worth, i also found 120ppm N to be kind of a sweetspot using calcium nitrate, lower in flower. i did used maxibloom also in a dwc once, ran in to slight Ca problems too using RO water but it did the job well otherwise. when not using RO i have plenty Ca in...

i tried to get a idea of what ppm you are running. you wrote "The mix I've been running for the last few years start to finish has been 120-40-180 NPK 90Ca 50Mg 3Fe. I ran 1/4 line" somewhere. that would be about what the studies say, low P, moderate K.

thanks for sharing your experience. i do also think that the "Cal Mag" problem can be related to your K supply. "But can't find the overall nutrient ratios there" me neither, just had another look, cant see any infos given on Ca Mg ratios. they prob not supplied K as a sole nutirent either...

most "eye opening" to me is this one (seems my links above are all a bit f... up, sry). https://www.mdpi.com/1643862 "The improved physiological state under 60–175 mg L−1 K enabled higher biomass and yield production, but K supply above 60 mg L−1 K did not affect yield production (Figure 2)...

btw. tell me your water valus and ferts avaiable and i can try to figure out a mix fiting above ranges from the studies.

really depends, for my recent grow. i just do soil grows atm with organic dry fertilizer. my tap is EC 0.7, 110ppm of it are Ca (CaCo3 so 70ppm avaiable Ca), only 9ppm are Mg, so some Epsomsalt is sensefull (while not needed on every watering in soil). maybe 0.2 to 0.5g a liter (for me), raising...

„Potassium concentrations exceeding 120 ppm in the fertigation solution caused a decline in cannabinoid and terpene content. Balanced Ca and Mg mitigated the antagonistic effects.“ 3:2:1 is about ideal, but its ok to go higher with the Ca:Mg ratio as far i understood. so 3:3:1.5 is ok too as...

i might try to stay a bit on the lower side for K and see. Ca is a given for me when using tap water, i can only play with the Mg there.

yes, i think i observed quite some K toxicites also.

just had a quick look, but seems all studies supporting above given ranges. correct me if i am wrong pls.

thanks, i will have a look. "new" is of course relative, to my feeling things moved a bit in the last good 5y. keypoint is somehow, much P and K isnt what we may looking for, hard to say for me, always gave a good amount PK.

It looks like there are new studies made on cannabis i have missed so far. Am curious to hear your opinions, especially for K. A little compilation. Scientifically-Based Optimal NPK Levels for Cannabis Sources: Caplan et al. (2017–2018, Univ. of Guelph), Bernstein et al. (2020–2021, Israel)...

Not much damage, its just the lower leaves who got slighty eaten. I wouldnt even worry if it where thrips in the garden, well i would worry to bring them inside to my tents of course. Glad its no thrips therefore, thanks. I like the praying also haha, for sure not caused by too much light...

Brain damage auto Got huge for a auto Thrips?

thanks, you see well, its a 3 Plants in 3 Gallon textile pots. they are in the smaller 86x86x170cm tent. just set to 12/12. maybe its just the cuts (was a old mother), but theyre throwing tons of budsites and stay quite compact.

These are my Ethos Candy Store RBX. Its time to flower then.

about 300km.

i might should give Barcelona a try one day. hit me up if youre going to germany things are developing, havent seen exquisite hash but quality of buds got way better allready.

havent followed it in the end. i bought some nets and found a source for dry ice, so i basically could give it a try.... but, i simply smoke my bud so far will see hen i give it a try.

am still here and growing :D. using the same "old" lights till today. i might should update a bit more here or start a new thread.
