You must have been reading about soil grows, because 6.4-6.6 pH is perfect for that. Hydro is a totally different animal. As I said previously, it's one of the most important variables you must learn to control when growing in water. Keep reading, the light will come on and then you can ask questions and try again. Dont get discouraged, everyone makes hells of mistakes on their first few attempts, but it will come.

And if anyone did suggest you to keep your pH in the 6.4-6.6 range for hydro, they were incorrect. Your plants can uptake very little, if any nutes when pH is that high. Here is a chart for you to reference when you try again. Remember, a pH of 6.5 is 10 times higher than a pH of 5.5, not 1 point.

It shows you the proper pH for both hydro and soil.

I start with 5.5-5.6, and once in flower I go up~ .1 point about every 3 weeks ending at~ 5.9-6.0. For the strains I grow, that seems to be optimal. Your strains may very well be a little different, but not by much.

Remember:
pH correct and stable.
no light on roots or getting in rez.
rez temps no higher than 72-74.
Start light on nutes and work up, makes life much easier, and avoids stress to plants.
Give them ROOM to grow. Dont try to grow 12 plants that are crowding each other, 4 plants with room to grow will equal same yield/watt +/- very little.
Address any problems you have yesterday, hydro is not real forgiving.
Keep NOTES, detailed !
Learn to keep mother(s) and clone.
If possible get a real pH/TDS meter/tester.
Also, get a R.O. system.
Purchase Cal Mag and Superthrive, learn what they do and how/when to use them.

Keep reading and asking questions. There any many knowledgeable growers here who can help you get things on track.

No matter how you decide to grow, best of luck:thumbsup:

bongerstonerd00d Reviewed by bongerstonerd00d on . ?on how constant of a drip? I set up a drip system and it didn't work out well.Think root rot ruined it.When removeing the hydroton it had a clearish slime down around ther area where the roots used to be.So I was wandering how constant of a drip and if any one knows what I did wrong.The ph was constantly going up so I was adjusting alot.Oh and I also used a little bit of blackstrap. Any ideals of what might of caused it? Rating: 5
