First Hydro. Need Canna Help

Hello everyone.

Totally new to hydro.
I'm in my third week of veg from rooted clones (5th-6th week from cuttings) and I'm not sure what amount of Canna Aqua and other Canna products to use. I started using the Canna calc after burning my first 6 girls with the packaging directions in the first week. The next batch went into a much milder solution, but also seemed to be a little nutrient hot. I've since backed off and I'm using about 85% of normal for this stage based on the Canna calc, but they seem to be in constant recovery and my leaf tips are turning up and drying. Again, bubble hydro. The plants are growing slowly. Most are only 6" tall, but my Fire OG are 12" tall. They have all doubled in size in 3 weeks. Most have good roots. Does anyone have a diary from clone to harvest using Canna Aqua? I need start to finish calcs so I don't keep stunting their growth with "guess mixtures" of nutrients. Thanks in advance!

Have a ppm and PH tester. PH has been at 6.0 give or take .2 since start. Really, I think it's the amount of chems I have been using. Started too hot based on bottle directions, but have come down since and have been better. My primary concern is that clearly I can't use the bottle or calc directions a week after clone/cut. Should I use 25% to start and go up by say 10% each week till at normal?

yes 25% and keep going up until you notice a lil tip burn or you can tell they just dont need MORE nutes...Canna is great stuff

Thanks to you both CKCKCK and Skinnyone. That seems to be what the plants want, a much lower dose I mean. I'll start out at 25% next cycle. I was really expecting much faster growth from DWC, but I'm pretty sure I've slowed them down with with the heavy nutrients. If I can get them up to the "normal" veg nutrient level in a week or so, (I'm pretty close now) can I start with full "normal" flowering nutrients when I change the lights to flower? Is it only based on PPM at this point? It seems like the recommended PPM goes way up in the Canna flowering calcs and the recommended PPM has been too high all along. Thanks again to all for your help.

You cant always go by the mfg recommended schedule.All plants are different in how much nutrient they need. Go with how you see the plants reacting. 25% then keep going up until you see a slight burn then back off. It will be the same for flowering. Patience!!

Hey, skinnyone. I need to start flowering pretty much right now. I will put in my HPS tonight and go to 12/12. When should I start the flower/bloom nutrients. I will change the tub tomorrow when my chlorinated water has cleared up some. Should I go to flower nutrients with this change or go another week or two with veg nutrients? I'm at 830PPM now with 250 being hard water. What do you recommend?
