Indoor Growing Scrog

Experimenting: Upped fertigation frequency to 10 mins every 2 hours, Vivosun pump at max, 1/4" tubing.
Day ~23. After 5 days of this, plants are happy, and might be growing faster than previous less frequent schedule, but hard to tell.
FloraNova Grow, EC 1.2, pH 6. Overwatering with rockwool might be hard to do?

(At day 23 you want that EC to be around 2.4 or 1300ppm, it's difficult to over water rockwool however I'm sure it's possible.)

This INFO above is wrong, i'm getting myself confused.

When the seedlings first sprout, I'm on 0.7ec then gradually bump it up to about 1.0 by day 10. By day 14 I’m at 1.3ec and will keep it there through the first half of flower.

I'm getting my ppms and EC's all mixed up.

Every time I've gently raised EC past General Hydroponics recommended 'Light Feeding Schedule', I've had nutrient burn. I don't know what I might be doing wrong. I'm going to follow your grow with interest in this regard since you've been successful with your EC previously. :thumbsup:
 
Earlier ones were DWC, but last one was rockwool. Had to back off the nutes
because of leaf tip burn, and probably too much nitrogen too: very dark green leaves
that curled. Back to the drawing board to mull what I might have been doing wrong otherwise.
In the meantime I'll get through this grow using GH's 'Light' schedule and see how that
works out. Thanks for your thoughts on this!

I know it may be obvious but to give so much EC use an adequate light power, Deano has one of 125w at 100% at 30cm in each plant, We don't know the final DLI but for so much EC it has to be high

I have two Aray 2's in a 2x4. Mine are about 1 yr old. 120-125 watts each at 100%.

DOA, did you mean 2.1 EC, or 1.2 EC for your seedlings?
Yes i meant 1.2 and not 2.1 for the grow, 0.7ec for seedlings. I really must check my posts before uploading. I have amended my other post for you to reflect this. :thumbsup:

Some have argued that we should all just agree to use EC and discard PPM. I've confused myself many times, trying to keep them sorted! This fellow explains why we probably should use EC, including the reason for the different PPM scales: The Americas have a lot more calcium in ground water than Europe does. He also explains what happens when plants are fed too much nutrient. See the 'EC vs PPM' section ...
