Damn that's crazy! I've used tapwater now in three different cities and haven't had any issues at all. I've never deviated from the box either except up-and-down the amount of base depending on strain, plus I use Silica which is a natural up so maybe that's why I haven't had any problems...interesting. Hell I don't even dechlorinate anymore.
Ahh, love the ones that fade to black like that! Beautiful!
With promix, you don't want to let the pot dry out but to go from wet to damp. The top of your medium should never be dry looking. Also, you shouldn't ever need to flush promix, but if the ppms or ec is too high then run some lower number nutrient water through. The runoff in Promix BX can be deceiving as sometimes later in flower the ppms/ec reads much higher than what is actually available.
What i've been doing so far in my flower rooms is water 3.5litres every wednesday, while every sunday i would feed about 980ppms with 3.5litres, currently i brought it both down to 3 litres per 3g. it never gets a chance to dry out and the guy at the store told me that it should be drying out. but he was thinking i was in HP. atm the last feeding i did was about 980ppm with 3litres. should i be waiting a day until its pretty dry then feed it with 400ppm?
Promix should never dry out, especially to the point where it looks light brown. Dry Promix has the nutritional value of cardboard. I know when BX dries out it separates from the side of the container, which can actually damage your roots. To combat this, I was taught to add vermiculite which actually keeps it from separating from the side when it dries out and evens out the texture. That and perlite which helps it dry out quicker.
ah ok well ill probably wait til this weekend too see how heavy my pots are. usually i would be watering in 1 hour but there all pretty heavy even with the pots i only add 1 litre every wed/sunday. ATM im using sensi grow A+B, from the looks of my veg plants there super green with no problems and i barely need to give them nutrients since i dont get any run off. i think im going to continue doing the 1 litre per 3g if it starts to get dryer and yellower then ill up the nutrients by maybe 200-400ppms.
simple, feed 6- 800 ppms of veg nutes EVERYTIME you water until about week 5 or 6 of flower,Ph shouldn't matter, it should change as it dries. then you can use some boosters if you want, but it looks like you might also have spidermites
im using Sensi Grow A + B and im going to check for the spiders, i feel like its just nutrient deficiencies just because i screwed up on that room
resist doing what? watering only 1 litre?
Will the spidermites go away after im done the harvest in about a week n a bit?
so basically i gotta spray my entire tent after the harvest?
Yes. They're weeds. They're st their best when they're pushed. Reaching for water and nutrients. Otherwise they get lazy. You want to promote vigorous growth. For that you need to make the plant work for it, not continually feed it. This is really a basic principle you need to grasp. I'm on my 3rd grow and I still have to resist the urge. If you really let the plants starve for water, they'll droop but I've never let them get to that point. The pots will be very light ( and individual plants will feed at different rates) and the top layer will be fluffy and light and dry.
how long does it take for it to dry off? i feed them sunday and there still extremely wet, i may go to the store and get a couple small fans
so i looked under my infected leaves of my plants and i havent seen anything that resembles spiders, not is on the bottom of the leaves anywhere that i look, i might have seen a egg but that was only on one leaf.
