Yes that's fine. Just dump your old nute and water solution and top up with fresh water, add nutes to desired ppm. All you have to do is keep an eye on your ppm!

Hey beachwalker! I'm just stating what i do. Don't know if it's wrong or right but has never caused me any dramas. I look at the water as my medium, if i was growing in soil i would have soil covering my whole root system to allow as much nute/water uptake as possible. That's just my thinking. And have had no issues doing this.

Could be a number of things..... have you got good air exchange? (Fresh air being drawn in and air being pushed out)

No b
NO but some say that an 18/6 light schedule is better for plants that aren't as healthy....? I veg under 24 hours with no probs.

too much light can make leaves drop. cobs can be intense. what wattage and high do you run them
when did you calibrate your ph meter and is it a good one or just a cheap $10. nothing wrong with the cheap ones just need to calibrate them often
ph perfect from advanced nutrients suck if you ask me granted i only used that product once but i dont really know how your adjusting the ph considering it stabilizes and self buffers it self also i dont think its made for dwc
you must be using allot of ph down to change your ph

Running 4 Cree cob 320 watts full blast also just changed over to advance nutients perfect ph I have one question on the ph perfect part my autoflower does not like high ppm the bottle ask for 4 mil per liter I have 2 10 liter buckets one for the plant and one to fill in water and nutients the ph is good but the ppm are over 1200 my question is if I cut nutients in half will the ph still be perfect or will it be off I'm thinking 4 mils is way to strong but I want the ph to be right, can I just add water to raise and lower ppm without worries about ph being 2 high or 2 low.

320 watts of cree cobs is still strong but @ 18 inch i would not see it being a problem. i am no expert with advance nutrients but i do know using it at half strength 2ml per letter the buffer dose not work correctly and yes at full strength 4ml per letter it burns plants if used every feeding hints why i say its not made for dwc. id bet all my money the nutrients it self is the problem but that's just my option. i only used it with coca for one grow and even feeding full strength ever second feeding it would burn my plants. i have not used it for dwc and honestly id never use a self buffering product in my dwc . i just use a part A+b nutrient and calmag. i flush my rez once a week or every two weeks depending how much they drink and top up though the week when needed
once you have topped up your rez by half its time to drain it and start with a fresh new mix

this is my option and its going to be rude sorry
fuck growing autos because 1 its waste of electricity having your lights on 24/7 or even 20/4 for just one plant. 2 you cant clone them making it shit for future grows and makes you need to buy more seeds what is more of a waste of money. 3 if you mess up you will get a crap harvester because they got stunned. 4 i don't see autos being a good plant for a noob to grow (not saying you are a noob)
the only pros i can see about growing autos is if you only have 1 grow room because you can put lots of plants under 1 light at different stages of growth with out needing to change light cycle

I don't know how you used ph perfect? I grow in dwc and have been using ph perfect perpetually for about 3 years and am now pulling over a pound under a 600w hps consistently. So cant be that bad. You always get the advanced nutrient haters....... yes they are overpriced and I only use a few of their additives but in my opinion its worth every cent in the end.

i did say its my option. if it works for you that's good
What kind of water are you using? If its tap water there could be limestone in it causing the ph to rise.
Try using distilled or RO water in one of the buckets and see if the ph is stable.
This video demonstrates the differences between tap and distilled water and why they resist ph change.

Sorry man, just saw your post! Yes you can cut strength in half and ph will still be fine. Off memory when i first started using it (when i had a ph pen lol.) the ph wouldnt hold at 5.8 for that long...? DONT try and adjust ph. It is chelated. Basically meaning that the plant can absorb nutrients at a much wider ph range! Just top up with water when plants drink and keep an eye on the ppm. If the ppm drops then simply add part A and part B in equal amounts (dont mix the 2 nutrients together. Put one in your res then the other) till you get to your desired ppm strength. If you top up with water and ppm is still high then you will need to do a res change. Wash bucket out, give roots a gentle rinse and fill back up with fresh water and add ph perfect to desired ppm strength and repeat as time goes on. Depending on strain and the water you use, you may have to add a very small amount of cal mag but the base nutes are fairly enriched with cal mag imo.

And yes the 4mls per litre is very strong i very very rarely use full strength. Also works on ro/distilled water or tap water. But you'll find plants will have more vitality and grow more vigorously with ro/distilled water. This is just my experience. Have been using ph perfect in Dwc for about 3 years! Hope this helps

Yes it works perfectly fine in Dwc. Experience is better than guess work. Sorry to sound like an arse hole but we're talking dwc not coco. You don't top your res up with full strength nute mix, you top it up to desired ppm. That way you replenish what the plant has used.
