Over fert or lights?

spelltwister · Dec 7, 2009

Hey all,

Just moved this plant from a 430 Son Agro to a 600W HiLUX bulb. The humidity also dropped < 10%. I was wondering if my leaves are spotted from over fert or new lighting + humidity.

Thanks!

Nope, more like ph problem. Check the run off and let me know what it is. Are you phing before you add nutes to water or after.
Remember the nutes will lower the ph, so its a good idea to do it after you have already added the fert to the water!

I usually check my pH before and after so I can see how much the nutes really affect the pH. I balance the final solution to 6.4-6.8. I will buy more of the calibration packs to make sure my meter is not off. That would be terrible!

Thanks for the reply ;D

I had that in the last few weeks of flowering because i watered with tap water for the flush.

I didnt see any issues in growth or anything so if its at the end of the plants life then whatever... :leaf:

that's a little high isn't it? i'd go around 6 if i were you

Is 6.4 - 6.8 high? I thought the sweet spot for soil was about 6.5, but I could be mistaken. Anyone have a better idea about this? My plant is just about to begin flowering (about 9 weeks old). I'm waiting to see if the clones take or not.

Thanks! I went out and bought some calibrators again and the meter was off! I would have never thought of this otherwise. THANKS! I don't know why I can't +rep you :/ But you deserve it.

ya around 6.5 for flowering is a good point to stay at

not at all. 6 would be waaaaayyy too low. in soil 6.8 is the perfect number. this will allow the maximum uptake of of nutes. i wouldnt get below 6.4 or above 6.9

10% humidity? thats fucking low dude. I killed 3 plants by just having it at 20%. Plants are far easier to deal with when the humidity is higher. If my grow room is at 100% humidity they can take having 90F temps believe it or not. If your leaves dont have a shine to them/are crispy and brittle they need humidity.

Over fert or lights?
