Potassium lockout on flower. How to fix?

All your plants have been pushed with Nitrogen(burned tips), which is perfectly fine up until now where you should cut back N and increase P and K and sit back and watch the flowers explode :) All your plants definitely needs longer than 1 week before ready for harvest, at least 3 weeks longer, if not 4 or 5 weeks longer. Plants are looking really good for a first grow 👍

Riega y mide el ph y el ec del drenaje de su maseta. Según los parámetros de la mención hay diferentes respuestas para su problema. Según mi opinión tiene problemas de ph y eso puede estar bloqueando algunos nutrientes necesarios para el crecimiento de su planta. Ponga en práctica lo mencionado y vuelva hacer otra pregunta con los resutaltados de la medición.

Im not seeing potassium lockout. I am seeing a bit of over feeding though with burnt tips. Seeing your giving them grow micro and bloom I don't think it can have issues with K unless its getting locked out. I'd lower the feeds concentrations and if you are not getting runoff, get some to help flush out any buildup. aorund 15% the pots volume. water in slowley.

So always add silicon to the water first, give it a mix, then your plant food. Some advise waiting up to 20 minutes before adding your fertiliser but I've not had any problems myself adding fertiliser right away after a good stir in-between. The dissolution of silica is strongly pH-dependent. Potassium can be derived from silica through the process of creating potassium silicate, a compound that contains both potassium and silicon. Noticed you added every week, and it's your first grow, I wouldn't have known to add it first on my first grow either tbh. Silica can bond in funny ways if salt minerals are added to water first. Alkaline nature of silicon will likely cause precipitation of other nutrients. This can also cause a large pH shift in the growing medium, further limiting the availability of other nutrients. Step 1) Start With Silica. Related Products. ... Step 2) Add your base nutrients. ... Step 3) Add your cal-mag. ... Step 4) Add any other additives last. ... Step 5) Finishing by pHing your nutrient solution. Good luck pal.

just watering it if u're gonna harvesting soon u've got planty of leave she won't starve

In TA ferts, stopping "grow" nutes actually reduces potassium WAAAAY more than it does nitrogen. I wouldn't deviate from the established ratios unless you're also using some sort of PK booster. You're much better off reducing overall concentrations(aka EC) than tinkering with the ratios. I'm not convinced it's an overfeeding issue. Runoff data would confirm if you need a flush or not. Probably not getting enough runoff and building up salts in your coco.

"Rinse conditioner" is a great way to get you to spend money on a useless marketing rip off product! Plain water does everything that you actually need to cleanse your plants........aka "flush". In my opinion, you do not have a potassium "lock out", which is almost impossible unless your pH is way off, you actually have a nutrient burning issue from feeding waaaay too much. Blue Dream, with its Sativa genes, does not need anywhere near as much feeding as an Indica leaning White Widow strain. Both of your plants are showing signs of being waaay over fed and now during this stage of flowering, the use of "grow" fertilizers should be zero. No need to flush, just reduce your fertilizing. Too much fertilizer during flowering will produce excessive leafing at the expense of flower growth.

Thats not potassium, thats calcuum and too intense light.

This is a good example of 2 strains requiring different nutrients. I’ve grown WW, knowing that it is sensitive to nut burn I will feed it at a lower ppm than any other plant I’ve ever grown. I cannot use that same nut formula for other plants in my grow, they will eat it up in a couple of days and start to turn yellow because of the lack of basically everything! Or you’ll end up feeding them twice as much to stay as healthy as the WW. A simple one off correction will not solve this problem. It’s your whole concept of feeding and what type of plant you’re growing. In this situation the Blue Dream needed a higher ppm than the WW in nutrients, or it needed to be fed more often. In any case, being so close to the end of flowering, any drastic changes may cause more harm than good. I would not increase the ppm to the nuts, rather give it an extra feeding every week or two.
