crinkle leaves and very little root growth

[hillbillybuddha]

I posted on here a few weeks ago because I was getting very little growth and twisting fan leaves.

I ended up lowering my PPM's and watering less. But I'm still having problems.

PPM's @ 550 CNS17
Water Temp between 64 and 69 f
1000w MH
Was PHing to 5.5 but just raised it to 5.8 because H&G Roots Excellerator calls for that PH.




Leaves are twisting, yellowing, and crinkling. Also, I not noticing any root growth. I'm now only watering my 6x6 inch Rockwool cubes once a week and they are still pretty heavy with water after 7 days.

Their normal growth seems very slow as well. I'm almost 2 months into veg and my girls are only about 14 to 16 inches tall.

Two days ago I added H&G Roots Excellerator.

what type of soil you in? Looks like lockout from wrong PH, and salt buildup. how often does it get watered?

lock out from ph i would set the ph to 6.5 in soil then you wont get lockout if you do adjust the ph to get the relevant element

I was at 5.5 and I'd let rise naturally but Roots calls for 5.8, so I set it at 5.8

I'm in Rockwool. I water when I can lift up a cube without a steady stream of water pouring out the bottom of the cube. About every 7 days. (Which means the roots aren't taking in the water)

What's your humidity level? Having similar issues from a hot/dry climate.

Just wanted to follow up. The Roots Excelerator seems to have worked. Got roots coming out everywhere and the Rockwool blocks need to be watered at least once a day now.
