Nutrients and Dwc


#1

Trying to plan ahead for my next grow,first time trying DWC,at what point do I start giving the plant nutrients.do I wait until 4th or 5th set of true leaves like when growing in soil or can you give it nutrients right after germination


#2

It is the same for al mediums and methods. Cannot give nutrients until 4-5 nodes of true leaves

i currently have no hydro shops around me and perfered to shop in person so i bought everything while i went on vacation and brought it back i have only had one grow and it was a 5gallon net pot dwc grow with some very generic nutrients for my first grow and i had very little problems with my first grow other than i used all cfl bulbs and it took a little time but got roughly 40 grams out of my plant but this time now that i have 1 successful grow and understand more i have built my 50 gallon fishtank into a dwc that will basically hold 20-25 gallons of water and the tank is 4ft long 16’‘x18’’ or so i have 4 air stone tubing and a 4 port air pump, clay pellets and 4’’ cubes…i have upgraded my lights and have a 300 w led and a 180 w led put my old cfl 200-300w bulb…my grow tent is something i built and am going to be 21/2ftx5 ftx 4ft then i can add 3 ft to it if i want but how many plants can i grow and i also bought RX Greensolution part A&B grow and part A&B bloom some liquid seaweed and some flora bud concentrate anyways what is the mixture for this has anyone had any problems should i do a scrog grow this time i also ordered amnesia haze i havent yet started my grow but am going to start within the month just want to do plenty of research before i start. I also own a digital tds meter but have never used it?? and a digital ph meter that i do use…dont really want to spend any money on a RO water system can i buy 5 gallon jugs of water at a fish store? and just PH it??? Do i use both part A&B at same time? is there anything i need to think of or do before also temp has always stayed at 72-75 and at 40% humiditiy i never had a issue there? last time i ran it a few problems but were caught very eary and fixed only problems i had was i needed to add hydrogen peroxide and epson salt last time but it was never more than a few leaves that drooped or got light spotting but it only lasted a few days

You can mail order our nutrient system specifically designed for cannabis, and it works great in DWC.

A lot of regular forum members, like @yoshi, have used it with great success.

You can even use stuff from a regular store’s nursery/garden sections, even miracle gro.

It is not the absolute optimal mix, but it is how I started in DWC, and it would work well with tap water that isn’t too hard, not much higher than a 0.1EC/50ppm/tds NaCl conversion, and then, of course, add the magnesium and calcium, as stated in the link, or add it with a Cal-Mag supplement.

happy growing,

Cookies93 yes you are to suppose to used the A & B in grow formula , and also the same when you get into flower , you used the A & B bloom together , it’s how the nutrient line has formulated the line you have . But if you want to get bigger buds and more of a yield than 40 grams , ILGM booster nutrients is amazing stuff and it is very easy to follow , the grow is like black liquid gold for plants , it simply works awesome , and the bud really give your plants that real purgent smell , and the THC Mass really does exactly what it says , they get fat , and very full of trichomes (resin crystals ) super sticky . Robert nutrients is great stuff , I order 2 at a time , but you can check out my haze I just ran with ILGM booster nutrients and advance hobbyist additives , and the amnesia haze did twice more than what I expected , since I’ve never growed auto’s until now . I’m still waiting on this stubborn blueberry , but it’s a mammoth for an auto I think , but it’s a Johnny come late , which is reall good , now it has the whole space to itself , when I growed them in the same small tent .
