Can you tell me what the problem might be?

First post but been reading here for over a year, and First I would like to say thanks for all the great info on here. Got threw my first grow with no problems.

Anyway most of my plants seem to be growing fine, First time to veg under florescent but seems to be working fine.
I use iguana juice for veg, only use 1tsp per 2 liters (says 3/4 per quart), and every other water, and sometimes I water 2,3 times with no juice.
I re potted about 7days ago so I have been using straight water. But some of the lower leaves on a few plants look burnt.
Just wanting to see if it looks normal or do I need to adjust anything. Thanks for any info.


Oh and if you can see the 2 plants on the left of one of the pictures,Is there anyway to keep them from stretching so bad? I keep them touching the light and they still stretch. And they are all bag seed.

to me it looks like the normal "the bottom leaves are not getting enough light" syndrome.

no biggie. fluorescents don't have much strenth in canopy penetration.

my $.02.

Thanks for the reply, I was wonder if it was a light problem, It's so hot here this time of year (98) I had trouble running my 400w hps. I have a 600w with a real cool tube, not my home made one coming with to big fans. So at flower I should have it up and running. Don't even want to try and flower under the floresents.

you'd be suprised with the yields you can get with fluoros, but it obviously can't compete with an HPS.

i hope to get my 600 soon!

I agree with Headshake...but...I'd follow the instructions on the bottle rather than skipping around, too. Advanced Nutrients are specifically formulated (so they say) for cannabis, so dicking around with their rates and schedule (or not following a schedule) can have negative results.

Takes forever for 5 gallon buckets (about what...8 dry gallons...?) to dry. Are you watering too much or too often? Cannabis prefers a wet-dry cycle. Do you have air vents drilled into the sides to prevent stagnant conditions?

You can search for the low stress twisty-tie training thread for the height issue. (LSTTT)

I'm running two 400w hps's in a 10 x 12 outdoor shed that's 96 degrees ambient right now. No cool tube. You'd be surprised what these ladies can thrive through.

I don;t mean to thread-jack... but Rusty... when you say hps outdoor, is that like in a shed or something?

Also, what is that you have between the lights and plants? looks like some kind of thick filter or something... is that to just try and absorb/dissipate heat or is it filtering specific light spectrums?

[Rusty Trichome]

Yup. A wood frame outdoor shed. Unfortunatelly, has full sun all day. Wrong side of the house, lol.

No, not a heat sink or anything like that, but I like your imagination, lol. It's a stick with screws every 2". Something I can clamp my clamp-light fixture with the UV bulb to, and I can set at whatever height I need. Seemed safer than clamping it to the lamp cord. :thumbsup:

The browning of the leaf tips is caused by too much fertilizer. One of the problems with powerful ferts is they don't tell you how frequently to use them. The manufacturer expects you to use meters and understand plants well. A soil grow doesn't require alot of fertilizer, just enough to keep them growing and not much more, especially if you're using small pots. Transplanting might be necessary. The short ones look good except for any burning you're seeing. Chances are the only way you're going to stop plants from stretching is to get a powerful light. I'd recommend a sodium type. I know they're expensive, but tying the plants or using a screen of green method to restrict their height might be the only other options. You can also try letting them grow a bit and then cut the top off and maybe this will cause them to grow horizontally the way you need them to.
