What feed schedule you using these days? I'm a complete moron for not figuring that out lol. You're a life saver.

So I haven't fed the plants in 2 weeks, been adding almost a gallon of water every day slowly starting to dilute it more in preparation for flush. PPMs read (on my pen) at about 800, a new full strength mix read in at about 950 for me. Has been about 2 weeks since i checked, just did another...

I also forgot to answer any of your questions lol So when I'm saying to closely regulate micros (basically everything besides N/K), it's basically because the micros have relatively sensitive mechanics in solution, especially around some of the other ions needed for the nutrients. By that, I...

That could be from anything tho- trichmore count seems about 3x denser on some of these phenos, if there truly was a P deficiency then the overall trichome count would be limited, and not allowed to express itself in varied concentrations throughout the different phenos (unless one pheno was...

Let me know if you can't find the PDF for this paper, I can PM you the file (I got it from JSTOR i think). The paper talks about both soil and hydroponics, so it kinda flips between them, but is really good at describing the differences (basically cation exchange and ability to hold insoluble...

I'm also not disagreeing that the plants may become more P hungry during flowering- but eventually they do match that chromatography reading (roughly), and this is where im really relying on my phosphate test kit. If they get really P hungry, I can check it and bring the levels back up to 30ppm...

Attaching a larger group photo, there's almost no clawing lower down and no tip burn. Not sure about bud size yet tho! That's definitely a factor I've been wondering about, so far I have at least one 3" wide nug on the far right plant. I'm getting a lot of popcorn buds below, but I think that's...

So in hydro, generally fulvic (low molecular weight) acids are considered more useful than humics. They do still have use in in-organic hydroponics as chelators. Basically all "non-organic" hydroponics mixes have chelated micronutrients in them. Chelators themselves are almost always organic...

Alright guys, it's been a few months of me running around here talking about 'low P', dishing out the theories and research I've been tracking, etc. Finally wanted to post some results. I'm about 2 weeks from harvest, and 90% of this grow so far has been on a custom low P high N diet the entire...

Thanks! Yea, most likely a bit hot on the N. I did just start the heavy feeding period maybe.... 2 weeks ago. But honestly, the 'black' one has been that way for about 30 days. The other ones don't look as dark. Going to be slowly watering down the solution for another week or 2, then flush...

looking good!

Buds are getting super fat now. This one is almost 3" wide on the black beauty ('H1') pheno (Hula Haze, Blueberry x Haze). I'm really liking the way that plant grew, and the bud size is amazing so far. If the smoke is good, this will definitely be my star pheno. Got a few clones going, hoping to...

how dead are the plants? You can try to trim some leaves and keep em half going until harvest- at least enough to keep the roots alive and defended.

ph update. Things have been fun in the ph world, but i think the plants have been fine so far? There's definitely far too little water for the plants, so I think that's ultimately the cause of my swings and such. I just jack the ph up every days (using pure potassium hydroxide solution now) and...

Glad to see some Chinese interest! Very cool. I'll mostly repeat what was said here: * Lower your temps maybe (20 C is fine, but it does invite some pathogens) * Use air stones (for aquarium) if not already. * Most importantly- beneficial microbes! Voodoo Juice, Great White, Hydroguard- any...

budz

Hah, ok last updates for the day. Finally got pictures that weren't.... orangified by the HPS. Starting with, the black beauty (yea, anybody know if this coloring is bad btw? lol): They're all wayyyy too close to the light now, I think I have to start slowly training a few buds away from the...

As far as the next grow, this is what I'm thinking for upgrades: 1) COB LED sealed array- this will also act as an air exchanger- the LEDs will be cooled directly with outside air, and vent outside, with (hopefully) a set of shutters that will allow air exchange within the tent. LED intensity...

buds are thickening up really nicely. My ppms and water level are both... dropping like mad- I'm dosing with nutes almost daily now. Keeping a really strong emphasis on N, K, Mg, SO4- and last week I finally saw a halt in vegetative growth. This will be my first official experiment regarding the...
