Fresh Pics, 4 plants. What ppm?

New pic... what do you guys think bout upping the nutes to 450?

yup..looks like its staring to have a N def. might wanna bump it up a notch

How about up to 800? assuming a Hanna meter is being used. I'd be more interested in knowing how often you're irrigating and changing your reservoir mix? What's the pH of the solution? What's the pH as time goes on? Just wondering....Happy gardening GrowIT!

i adjust the ph daily to 5.5of course im using a hannah meter! We had drippers on until the roots hit the water. We change the res once a week. How is the way to solve potassium def.?

im seein a start of wanting some nitro, if you think your getting a potassium lockout comes from salt build up from your nutes. i would go with a mild 3-1-1 for vege. around 700-900 ppm .
