Hoping someone out here may be able to offer some new advice as I have been reading the posts here since I started growing. I have been using ebb and flow system for 2 years now, about 6 crops, and everytime I get to flower stage the plants start showing signs of every deficiency you can imagine. The ph is within range (5.5 - 6.5 adjusted every second day, approx), the nute mix is according to specs (1200-1500 ppm) so I am assuming an nute uptake issue but nothing seems to make a difference.
I am using 2- 2' x4' tables hooked in tandem, 5" rockwool cubes on a bud blanket, a 75 litre resevoir with air stone, changed weekly. I have tried numerous flood patterns to no avail. I would think root growth should be more vigorous than it is but that is a guess. I am using the same nutes in an aeroponic system with great results.
The tables hold 14 plants, each, to a maximum height of 4 feet. An interesting thing is some of the plants look just fine!
If anyone can think of anything I can check I would be highly appreciative.
Cheers!
