Ph and R/o water using bio bizz nutes in Coco

[nuggiespl]

My mix is 50 coco "Bio juice" 25 pert, 25 light warrior. I'm using Ro water, I started at 5.8 and have worked my way up to 6.2, I just started using a tea from my local shop. The other day I was talking to a experienced grower, he said just mix nutes up and feed no ph nothing. I have been adding 250ppm of cal mag, then nutes, then tea, and trying to adjust the ph but the meter jumps all over the place, and yes its calibrated weekly. I would like the idea of just mixing nutes and feeding no ph, I did get a stable reading at 5.8, with everything minus the tea. I have noticed when adding the tea thats what I think causes the fluctation. Since Ro water has no Ph the ph is what is added to the water. I'm using the bio bizz nutes, I have searched deep and wide and think I'm in uncharted waters. Which is why I should have stuck with coco specfic nutes, but 3 week into flowering to late now.

I don't think this was a good idea. I tried it on my moms and didin't work out but nothing a flush won't fix. Unless it was from the dramtic shift in Ph that caused these ill effects hmm any thoughts. I was around 6.2-6.3, when i tried method above it was around 5.8 Thanks in advance
Thanks any help would be greatly appreciated.

The experienced grower was probably used to growing in a soilless mix with lime added, or in compost.
Start with your calmag, then add your coco nutes- it's not too late!- then adjust pH, then watch your buds fatten.

So u think i should change to coco nutes, I actually have what i think is decent bud growth for 3 weeks and 4 days into flowering. Just give a good flush and switch to coco specific nutes. I didn't quite understand your response sorry and thanks again stinky. I have been using the Biobizz recipe in the grow faq posted by latewood, I have been reducing each recommended dosage by about 1-2ml. Thanks I love this place.
