A shot of cal/mg would do her some good. It's also high in nitrogen.

I put my moisture/light/pH thing in the soil and it is high in alkaline. We have a lot of Alkaline in our water here. Soil is made out on my growers farm. She has grown for 30yrs now. Never had these problems till this year. What can I use to compensate and bring the ph down?

Hi Growmies, Two weeks ago i noticed that there are some yellow stripes appeared on the top leaves. The PH fluctuates in DWC can this cause some micro nutrient deficiency but I don’t really know. Do you have any ideas what could be? Thanks

Yellow streaks between leaf veins
All three of my plants have light green/yellow streaks in between the veins on the leaves that have been present since about week one (week 3 currently). Could this be a magnesium nutrient deficiency, PH issue, or perhaps just overwatering?

Top Leaves are becoming yellow from the inside out.
Hi, anybody know what the problem is with this plant? The top leaves are becoming yellow/white from the inside out. Also the leaves have a different shape. The plant is in open soil and I give her water and sometimes some veg nutrients. Thanks in advance. (Last picture)

Stunted leaves
One of my plants is having a hard time - it's technically growing as fast as the others but it's leaves are half the size, slight discolouration and cupping. I suspect Mg, PH or overwatering may be the issue. All variables for each plant are exactly the same.

A few of the leaves started to get yellow spots along the veins. I was pretty sure it was nitrogen deficiency so I upped the nutes a little. Over the next day or so, 2-3 different leaves started to curl down at the tip. Is this too much nitrogen?

What to do? Where am I at now actually? I’m lost and slightly discouraged
When should I add happy frog fruit and bloom? This is my 3rd grow and im 0-2! I have a overfeeding problem but I’ve learned to be corrective and precise with ph and ppm and be pest preventative as well (heavy handed waterer as well..im trying). It’s day 5 of flower and I’m lost

Crispy Yellow Leaves
Inflow EC=1333 w/ PH=5.8 vs Runoff EC=658 w/ PH=6.0. Insufficient nutes due to light intensity? Perhaps my PH meter is inaccurate? Light is 42 inches from canopy or ~600 PPFD. RH 65%, Temp 80 F.
