My ph is around 7.2 but im growing in living soil so i cant really add bottled cal mag. I have run bottles up to this point and im making the switch to living soil to try it out. Alot of people say good things about that style of growing, its just getting use to it on my end

I have a good amount of runoff, i have them elevated off the ground and those plastic saucer dishes under them to collect the runoff. Those dishes are full everytime i water and i dispose of it, the water cant get sucked back up due to the little stands they're on

Im using humboldts county for the nutrients with cal mag and recharge once a week. Im doing water feed water, and i water until runoff everytime but ive never flushed them because ive kept my ph around 6.2 to 6.6 every watering and my ppms are usually within range. Last night i fed nutrients and my ppm was 1690 and my ph was 6.41 on that plant in the picture i have 3 that are affected though

This is how they are looking today, definitely getting worse. I wouldn't think im overwatering because i water when i can pick the pots up with one hand which is usually around 3 days, maybe a nitrogen deficiency its starting to move up the plant by the looks of it. Its affecting multiple plants at the same time

Im in 5 gal pots, i water until runoff when they feel easy to pick up, about every 3 days

Ph of my dehumidifier water before adding any nutes or anything is around 6.6 to 6.8, thats right out of my brita. After i water my plants my runoff is usually around 6.3 to 6.5 throughout the grow

I do use my dehumidifier water for watering my plants but i filter it when it comes out of the unit with a brita, i thought maybe that was doing it but i dont think it could? It has below 10 ppms every time i check it and ive been watering with it for like 3 weeks now. Maybe im not supposed to use that ?

Definitely could be, ill try to attach better pics. I can take them out of the tent if need be for better pictures. I give them cal mag every feeding so water feed water feed. Also when i feed they get a quarter dose of Humboldts magnum(magnesium). Should i give them it every watering or just up the dose when i feed you think ?

Okay, it my first grow and i saw those balls growing in the middle of the v with no pistols coming out and got worried. Thank you for your responses

@Mr. Grow It In the first picture it looks like the leaf has a hole in it. Im on about day 30 in veg i looked at them with my micrscope and saw those, they aren't moving they just look like white dots, maybe trichomes

Its been like a week since i first started my deficiency question and i took your advice and it worked! No new brown spots, so thank you guys for that help. Some of my new growth has dark green tips that are curling but its only a few so nothing major i believe. I've been watering every 4 days roughly when the pots are dry and light. Today i noticed this... is it a pest or nothing to worry about, again thank you @Mr. Grow It

@Mr. Grow It the other day when i watered until run off i was putting in 6.5 ph and getting out 6.85 but my ppm was like 2500 ive seen some of your videos were you say its fine for that high ppm in ffof cause its organic but in reference to calmag is it okay to add it with that high of ppm ?

@Mr. Grow It okay thats great info, thanks for responding. The only other question would be should i water until runoff in my 5gal fabric containers with them only 3 weeks old and is it okay to add cal mag this early in ffof? I was worried the brown spots/ brown tips were a calcium deficiency or something. And should i cut those leaves off?

This is how they look today, definitely getting worse. I checked my light distance also but its 24in away running 2 tsw2000's on a light mover in a 4x8 tent that seems in

I was watering everyday in small amounts, basically not watering enough for any runoff but making sure the soil was dry before i watered again, roughly a quarter gallon of water everyday

I calibrated my pen and checked again, 6.85 ph and my ppm was just about the same around 2550

Okay ill start flushing it with straight ph water and ill calibrate my pen, what should my ppm numbers be at in ffof this early on ?
