Hey guys,

I'm a first time grower and my THC Auto Bomb's have started looking pretty sick.

Here's my setup

6 Foot tall grow tent
250 Watt HPS
No fertilizer soil & cow manure
Plants are autoflwer's Feminized THC Auto Bomb's
Not using nutes, just PH'd Water

The leaves are turning yellow and dying

Hey mate, Cheers for the quick reply! Ok N deficiency ay? How do I check the soil run off? I have checked the Ph of water and Ph down'd it to 6 - 6.5??

soil runoff is measured simply by watering the plant enough to have a bit of runoff come out the bottom and measuring the pH of that water, or buying a soil pH meter (would be easier with these size plants imo)....i would attempt to get a measure on that before giving it nutes, as it could simply be a lockout and nute feeding would burn the plant. also i'd keep your water closer to 6.5 than 6.0 because cow manure is naturally acidic/increases acidity over time, so the likely cause of this is lockout due to low pH problems. i had the same issue on some of my recent plants and i just raised the pH of my water to 7.0 no nutes and problem solved

Wow awesome info there mate, really appreciate it. I just ordered a PH meter so I will be able to check it when I get that. Thanks mate :)

Hey guys, quick update, I tested the soil runoff ph and the big one is 8.0 and the little one is 6.7. They seem to be getting worse as in more leaves dying?? Any other ideas guys?
