Don't know what to do

I'm starting to worry about my plant height. I am only 4 days into flowering and I have less than 6" to grow before my plant hits the light bulbs. If I put a screen there, will that be okay? What will happen to the plants as it keeps growing into the screen? Also, some of my leaves have brown spots, and some are wilted. I cannot tell if this is nutrient burn or heat stress. Pictures posted. Thanks in advance.

How old are the plants? What kind of light, it looks like daylight CFLs (switch to warm white CFLs if it is)? Have you looked into ScrOG yet? Tell me about your water and nutrients.

The plants are about a month old, from germination. I honestly don't know what kind of lights I am using. I bought this system on eBay, it just came with lights and nutrients. My nutes are in little baggies, G for Grow, and F for Flowering. I use distilled water.

Ugh, start over after this. Have a system you actually understand. For the moment, it does look like you're still using 6500k. You need to switch to lower spectrum bulbs. Consult indoor growing/CFL forum for more information. Additionally research low stress training or LST. Might work, good luck.

I understand the system. I just don't know the type of bulbs and nutes I am using. My plants have been doing well, except for these burn marks. Does lower spectrum just mean lower wattage? I have looked into LST, but I am scared of breaking the plant.

i would like to say that is some kind of nute burn , and something else i noticed is your water rez is clear . that is a big no no, roots need total darkness also algae can grow because of the light penitration. hope that helps.

I agree with Grizzly. Keep the net pots but get a light tight container. Get a Rubbermaid container. Also, put more hydroton in the net pots to keep light from getting in. Light is not good for root growth.

You want 6500K for Veg and 2700K for Flower. It should tell you on the CFL light package. Get higher wattage bulbs too.

I am a newbie but am growing a successful grow, thanks to all the readin I have done on RIU. I went through the same process as you initially.

Good Luck!

Thanks, I'll look into lights and a different basin. But the roots don't seem to have a problem growing, the roots system is covering the bottom of the container.

I suspect the unknown fertiliser.

If your growing quality herb your going to have to put in some $$ and time reading as well as experimenting, what works for one grower may not work for them all.

I suggest a change of lighting, as others have said, and a change of ferts. I have grown in clear tubs (does not affect roots but promotes algae growth that eats all your ferts before the plants do).

I'm guessing your nutes are chemical based and so you may want to consider a H202 regimen to keep algae and fungus out of the clear reservoir.

You had better start on LST or ScrOG, you do know these plants grow to be 4ft - 9ft tall if not topped or trained right?

I can see how the unknown nutes could be a concern. But the plant has been growing beautifully with no problems. And I did figure out my lighting. I have 2 6500k bulbs and 1 2700k bulb. So I need to replace the 2 65's for 27's for flowering yes? So should I just put some H2O2 into the basin every couple of days to solve the algae problem? What is the difference between LST and ScrOG, they both involve bending the plant right? I'm scared to do that, what is the easiest way to go about it? What does it mean to "top" a plant?
