100% nutrient lock out. Using these kinds of nutes are ment for hyrdro setups or soiless. They work better in a rez or irrigation line of soiless mediums. Soiless is ment be constantly moist and high frequency watering. When you let a soil media dry down alot with these types of nutes it creates higher concentrations and nutrient salt build up on roots. I would cut back on the nutes alot and try some foliar feeds. I would agree that using a rich organic soil along with these nutes could create unknowns. Its normal to let a plant stress around week 7 but you want it to stress from being root bound, starved of nutrients or lack of water. Not from nutrient lock out. Diagnosing individual deficiencies is a hydro or soiless thing, which can be adjusted but soil is different. Just my opinion.

It just needs more food. It's in peek demand right now. I see signs of N K Ca and Mg deficiency. There's no way you locked all those out at once with just mild symptoms.

If they were my plants I would go to 100% of what your food recommends.

They're gonna be fine. Totally normal for the plant to sacrifice the fans for the flowers.

^^ agreed

Dunno about the lock out as I don’t know enough to call it either way it needs ca/mg & food

And apparently any herbivore poop is awesome. Especially the Chinese bat guano.

Guano is what I use albeit mine isn’t Chinese
I used to use rabbit poop as well but it can be very strong when it’s fresh it’s better dry
Also depends what the rabbit’s has eaten

N def starts from the bottom up, if anything it looks like there is a P (which is rare in soil), Mg, and maybe zinc iron def but usually Iron/zinc looking def is nutrient lock out in my opinion.

with all respect sir, i think you dont know what your talking about. If you knew even the slightest bit you would know the amount of nutrients he fed are on the lowest end, also you probably dont have a nutrient lockout when feeding minerals and your runoff ph is almost fu... neutral that late in the grow, theres no buildup how can it with that tiny amounts. But you also probably dont even have an idea what a low or high amount is.


also "these kinds of nutes" how you call them,. simply mineral fert., ist not "ment for hydro or soilless", its used for everything, just the dosage differs.

i just looked at their feeding plan ones more and counted together what they tell you, so from week 3 of growing phase, following the protocol you end up with 12-8-20, or 120ppm/80ppm/200ppm...thats actually reasonable and the potassium is a bit higher than it has to.

From week 3 of flower you end up with 10-20-20, which is higher than you need to both on potassium and phosphate. Just keep the base recommendation of 12-6-12 in mind. So theyre a bit high on potassium and phosphate, but nowhere close to a lockout scenario. You gotta go really stupid on the doses to get a nutrient lockout on a healthy plant.

And with nitrogen theyre on the lowest still reasonable spectrum. So i wouldnt cut down on N, but in bloom you can easily cut down to 50-60% of their recommendation. Meaning, keep blend at 100% but only use 50-60% bloom.


But this company is just awful. 40 ml product/ gallon and they also want you to take 40ml of other supps per gallon. 80ml of expensive but very nutrientpoor soup per gallon of water, wow.

just do yourself a favor and go with a regular cheap mineral fertilizer. It really makes no difference. Plus a little calmag, only when you dont know if your tapwater contains enough. Where i live, the tapwater has enough, it has actually as much Ca and Mg as a mineralwater out of the bottle.
