Need help - First Indoor Grow - Flowering

[Ozymandiasza]

Heya,

This is my first indoor grow. I grow under 2x100W LED UFOs (Samsung and OSRAM deep red) in a 80cmx80cmx180cm tent. Unfortunately, this plant started it's life on my balcony so it was over-vegged. The lights are right up to the ceiling, so can't go any higher. It's growing in a 13L pot. The strain is "Cheese" (clone I got from a friend) and I've had 0 problems with the grow until this.

The leaves seem to turn yellow and the get this brown tinge to it. I've looked through many resources and barring the yellow leaves, I've been unable to find a solution. Only certain parts of the plan seem affected as some branches have excellent colour and healthy leaves.

Any help would be much appreciated.

Hello, it seems there are a few things going on..severely red stems everywhere, looks hungry but I'm sure some longtime growers can certainly help.
What are your temps lights on and off, rh, watering schedule....do you add any supplements ....etc.
Good luck

I know I am not much help on this, but may get this rolling for you with the bump.

Unfortunately, of all things, I don't currently have a temperature and humidity meter. The 4" (280m3/h) in-line extractor fan runs 24/7 with a smaller fan near the intake also running 24/7. Nothing extreme in terms of heat/cold. I water her about once a day with enough to get close to filling the pan at the bottom. The water never sits there for very long though. I also spray light water over her about every 3(?) days. Since she's become sick I've been lowered the water amount to let the soil dry more since she was drooping. I've upped the nutrient content with an extra 1.25ml/2l as well.

Since this is my first indoor grow, I've already learned a lot.

Thanks for the bump

Ok...if you are in soil, that is A LOT of watering. Try the pickup method..when soil is dry and NEEDING a drink, first lift pot to get a sense of weight. Then, a good water with some runoff, not a lot. Ensure ph is 6.3-6.6 , allows uptake of nutes. Not sure what nutes you use, but less is usually much better...say half strength. Feed, feed, water, repeat when plant requires water.
Use your wrist, the underside is more sensitive. This can tell you how close to place your lights....if you think it's too hot after a min it is too close.
Have a fan blowing on it to help with circulation and cooling.
Good luck

Well, it's a start.

Your post inspired me to go buy a temperature and humidity meter, as well as a soil pH meter. It really is needed...

Readings: 28C (82F), 52% humidity
Soil pH: A touch above 7.
Soil Water Content at Root Level: Moist.

I wouldn't trust that meter one bit. You get what you pay for with stuff like that.

I agree, however, it is better than nothing.

Hi Ozy,
I think Freddi has you on a good road to recovery. I just wanted to ask you about your water...just using tap? Hard or soft? I'm a believer in getting Ca and Mg nailed (in consideration of H2o)...first and then I add in whatever else I need or want.

Yep, just tap water.

Yep, just tap water.

For plant use...you need to know more. Look online for local water district reports. Under 250 ppm can usually grow ok...higher and people run into ph and Ca problems.

Hard water freezes into cloudy almost milky ice...that'll give you a clue. Look at an ice cube...
