I don't see any effect in Mg reduction to be honest. Almost 1 week since.

I raised the temperature to 84°F, with leaf temperatures ranging between 83–85°F. While the improvement is really slow, there seems to be some progress. Here are two pictures for comparison: the first taken on 11/22 and the second today. What are your thoughts I reduced to 450pffd yesterday

Gonna try w/ some cuttings for testing, ty

I've succesfully run multiple runs with this coco & this nutes reaching 800-900g/m2. I moved to another location and cant make it work since april. I tried reverse osmosis water to discard the water but didn't help

Those 3 marked plants have a special brand of coco which is pre-buffered. The rest and worst ones are made from coco bricks and buffered by me. These 3 are growing faster and stronger, though they also have some deficit signs. Not as strong as the rest And this one is from a greenhouse...

Good point. However, i would have tu use less if using penta since it has more Mg in it. but still isnt such a difference (8%). I dont think it really matters. Those quantities are for 750L = 200 gal of solution

No salt buildup, checked with https://bluelab.com/usa/bluelab-pulse-multimedia-ec-mc-meter and by runoff

Kept it fully saturated, same problem. And when did it people told me it was overwaatering lol

I also grow in coco coir pots outdoors. Will try with a small batch.. Still i dont see how a higher amount of Mg will result in Mg deficiency, i think i should see a Ca deficiency in that case as Mg is competing with Ca.

Im applying chlorine to reach 400mv ORP as oxidezer. And regarding the expiration. I tried using new salts, no success. This is the formula These are the salts

Hi guys. Sorry for the long delay. Im still battling with this. I suspect this is Mg deficiency pH is at 6. I tried these without success Fungicides Chlorine at nutrient solution at 400mv ORP Trichodherma Different ECs Osmosis Water Different source water Desinfect whole water system Last...

Hi Most of them are looking like these. R/O Water Ec 1.8 pH 5.8. Water temp 18/21 Celcius. Ambient temp 24C. 65-70% humidity Any opinion? I tried many different watering strategies, no improvement. They are drinking but can't make symptoms go away. I suspect FeEddha is expired (bought it...

Hi, Im experiencing what i bet a nutrient burn in my plants. I make the nutrients by myself, i wasnt having any problem in the past but it seems something is going on with the coco (It is reused coco) since im using the same water in aerocloner and plants are fine Few days ago did a flush and...

Hi folks I've succeded with a 12x12 sealed room with 1200PPM.. Using CO2 tank, dehumifier and AC Now i want another room and i was considering doing ventilated to save costs associated with dehumifier and CO2 equipment and electricity I live in a dry area so my plan is to as follows: Using...

Hi guys Im on week 4 of flower. Im using this nutrient solution: Is it potassium deficiency? I pre-treated de coco coir Any suggestion?

Can i replace Iron DTPA for Iron EDDHA ?

If i simulate with those number the relation 1A-1B-1D i was using this are the results So this appear to be very low P, which should't be a big concern in veg but also low K Looking for K deficiency: https://www.growweedeasy.com/cannabis-plant-problems/potassium-deficiency...

Holy shit, it seems those % were really bad and that the seller doesn't know the difference between quantity and concetration. So, apparently these are the good PPM for each component I play a bit with some salt components to try to recreate the salts they use to double check the PPM table...

what I mean is if the amount of calcium and sulfur that results from that combination is OK (orange column)

Is that amount of calcium and sulfur ok?
