Leaf Curling and yellowing on three week old plant, how to stop this gettign worse?
I am getting leaf curling and yellowing on my 3-week-old Hulkberry plant. I suspect nutrient burn, even though I am using what was recommended by my local grow shop and also RQS's website. I have reverted to water only and raised the light higher. Anything else?

Nute Burn? Or something else?
I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated

Is this nute or sun burn? What should I do to save my babies ?
I upped the nutrients to week 2 of veg state (biobizz) and put the light to 50% intensity. I put the light at 6 inches above recommended height (which is recommended on the Mars Hydro website for beginners). . IS THIS NUTE BURN OR LIGHT BURN?

Brown yellow leaves?
Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

Surplus or deficiency?
Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Day 20 Flower. Leaves curling
Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?
