It seems you are well on your way to mastering the art of hydro.
Your plants are looking much better than when you first got them. After looking at the first set of pics I wasn't sure those clones were going to make it. Just yesterday I got a hold of purple Kush x 2 and a Great White Shark Clone from the local collective. I wanted to put them in DWC but it would have involved washing the dirt off the root ball and although I've done that before I figured I would grow them out for 4 months and then take clones and use the clones I just got as mothers. I smoked some dried buds of the purple kush when i got them and it was pure purple grape tasting goodness. Purple strains have their own following I suppose. Like some people like Haze I like the purps and am always on the lookout for new blue and purple gear to add to my quiver. I already have 2 hashplant mothers, and just started flowering a 3rd in a Smart Pot under a HPS 1000 Sun Master, a Warlock mother (the lock in Rocklock) and I am growing 5 plants total in DWC. Warlock is an amazing strain and the only reason I got the clones was the guy who had them had too many and gave me 2 of them. Thank god he did because they are amazing plants that grow very fast and look like they have very good genes. Once you've been growing for a while you can tell when a plant has crappy genes from too many crosses or whatever. Once you get a hold of a strain with good genes it will outproduce the other plants its grown with even if they are treated the same. There is a saying. A slow horse and a fast horse eat the same amount. One other Sativa/Indica cross I am growing is Carnival which is a strange strain crossed in Spain. The leaves turn almost white when flowering and is reported to have 22% or higher THC. Even the stems of the leaves and branches have THC glands on them LOL. It has a very unique fuel smell, and usually stay away from Spanish breeders but this plant looked more Indica so I gave it a try. The roots on that plant are amazingly dense and big. This is my first time growing Haze and it is HUGE and bushy. Looks more Indica than haze and the branching is very unique and uniform. I like DWC and made some home made waterfarms by taking the drip ring and collar and putting it through a netpot and also adding airstones. I also run a GH Waterfarm but I think they are not that great. Black is a better color for a pot because it seems to cut down on bacterial growth and also you don't notice when it get's dirty. My waterfarm also needed to have twice as many holes punched in the bottom because they do not come with them drilled wide or enough holes and when you get later into flowering your Water farm can actually overflow. So, if you do get 1 of those beasts drill a ton of extra holes in it. I would recommend building your own from 5 gallon buckets (5 or 6 bucks a piece, sometimes cheaper on sale) and netpot lids (also cheap) and airstones (3 bucks a piece) and some tubing and check valves (5 or 10 bucks) and a air pump with two airlines (I like to use 2 airstones 3 bucks a piece, and an aquarium air pump about 14 dollars) so for about 20 bucks you can build your own and buy the kit which comes with the drip collar, its called the Farm kit for about 24 dollars. That is totally optional. Not sure the drip collar even helps that much. So for about 40 dollars a unit you could build your own water farm and it would be just as good if not better because you get a bigger zone for your roots. Fill it with 2.6 gallons of nutes and away you go. I want to read up on this Dutch Master Gold Range Zone. What is in it exactly? I will have to check out their website. I mostly use Advanced Nutrients or Gen Hydro and Fox Farm to veg. I have found some nutrients don't mix well with young clones getting out of transplant shock and the FF Grow Big has been a good one that all strains seem to like. For flower I have been using Connoisseur but that may change next grow. I think growing hydro is a lot easier than soil once you get it set up but you have to be very careful not to add too much nutrients. It's always better to be on the safe side and give them less and add more if needed. Also, that was really smart to get the RO filter. I want to get one of those myself. I need 1 badly as a matter of fact. I am on well water and the water comes straight out of the ground with no filter at all...so yeah. I should probably get a TDS meter also. I only have a PH meter so I cannot test my EC or PPM. That's next on my list but I just got set back so much by Christmas, buying a bunch of stuff, a dehumidifier, a pellet stove, and a bunch of presents for my family. Hope you get some good smoke off those plants and keep posting pics. Cheers.
Ya I think these bubbleponic systems are prone to it but they can & do give explosive results. I would be honored to help out, if I can & can tell you for sure Dutch Master Gold Range Zone!!!!!! RO'ed water is a big plus, & like to super oxygenate the RO'ed H2O 18-24hrs before nutes & re ph. I am here & you can ask away anytime. ~H~
the Dutch Master Gold Range Zone has a total nitrate nitrogen(N) of .08%, Soluble Potash(K2O) .15%, Sulfur(S) .06%, Water soluble Copper(Cu).1% Derived from Potassum nitrate & Copper Sulfate @ rate of preventative 5ml/5 gallons or if issues aggrressive @ 12ml/5 gallons. They also have a beginner nute for clones call Ducth Master Gold Range A.P.S., I have not tried it but I am making a Aeroponic Cloner & plan on trying it, the also Have a non hormone based clone dip called Dutch Master Gold Range Replicator. I am also using their foliar spray Liquid Light & wetting agent Saturator with great success. They even got a product to turn your hermie back to female called Reverse!
I used the Advanced Nutrients Sensi Grow A & B with great success @ the end of Veg & will be using it until I have used it up. I then will switch over to the DM Gold Range Grow A & B, not because I don't like the Sensi Grow but because I have had so much success with their other products I want to see what a pure Dutch Master Gold Range Grow would look like! A meter is a good thing, I have a Hanna & Oakton both Ph & PPM. It sure make thing easier!!
All 3 Hydro stores in my area carry @ the very least Dutch Master A.P.S., Liquid Light & Reverse!!! Hum, I wonder!!!!LOL!!
