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?

Did my homework First table is 1-1-1-1 relation Second table is with adjusted factors to match this ratio: 122-99-171-68 So the factors are 0.6 - 0.15 - 0.2 - 0.5 which translates into 4 A/1 B/ 1.33 C/ 3.33 D. Seems legit? Below the pictures of the calculator. Put 3.78 ml to convert to...

Let me say it I consider these instructions pretty useless Pretty self explanatory: Seedlings : 300 - 750 ppm Vegetative: 750 - 1200 ppm Flower: 750 - 1500 ppm This ranges are fucking high in my opinion Then, it says how to put each nutrient: Basically shake and put 5 ml / 2 l water (which...

This is C. Let me find the instructions and translate them

It is a sealed room so that is not an option, I lowered it to 700 but i can go to 400

everything is stable as a big rock, havent seen any drift in pH since many weeks which is really bad as normally ph should increase

Took your advise, i renewed the solution. 30ml A, 10ml B, 30 ml D 320 ppm, ph at 6. pray for me

Also considering switching from chlorine to h202

Look at roots, I think this is the culprit. And it seems to get worse where root touches the water, any new root that pops out turns to brown quickly. Water has 1-3 ppm free chlorine (measure by chlorine test) Any suggestion? Tap water is 130 ppm, im thinking of buying distilled water and...

Yea it really does. Look, same strain, same nutes, 560 ppm, 6.2 ph, no CO2.

Sure, in Veg is A+B+D (C is for flower) in equal part each

Thats true, but some deficiencies also show tip burn

Nutes are no known for you as I live in south america and it is a local brand. Water fluctuates between 18 and 22c. Cooling with chiller

Look my post on 20/Aug, it was showing deficiency without nute burn, that got worse with time and finally tips started to turning brown
