Hi,

Been looking through the curtains at the site for a while, great place, lots of info and finally decided to give it a go.

Have a small problem with a couple of our plants, think it could heat stress, maybe a nute deficiency as well and was hoping that someone could help.

E-indoor or outdoor Indoor
E-soil, soilless, coco, aero, or hydroponic Soil
E-specific medium 10L Pots
CSL-Soil type/brand Bio Bizz All Mix

SCL-Anything you have added to the soil Bio Bizz Bio Grow Organic Plant Food - After 2.5 weeks (have had 1 feed with this)
SCLR-Soil or slab runoff pH Unknown
E-Water source Tap
E-Source water pH Unknown

E-Age of plant 3.5 weeks
E-Type of fertilizer
E-Rate of application
E-Lighting source and distance from plant 400W HPS - 38cm/15inches
E-Air temperature 81 deg F /
E-Air % Relative humidity 35
E-Lighting schedule 18/6
E-Type of ventilation your room has 4" Fan

I know I need to get a ph testing kit and will be doing so ASAP. Looking through other threads in this group, the yellowing on the bottom leaves looks like it could be linked to heat stress when we switched from the fluro to the HPS and those were some of the only leaves around at the time. They were under the fluro for about 2.5 weeks and have been under the HPS for about a week now. Have a 4â?� extractor fan in the tent (Bud Box 75x75x160) as well as a fan blowing air across the top of the plants.

Iâ??m sure all you people know what itâ??s like on your first grow, would be very grateful if someone could put my mind at rest as to what could have caused this. None of the new leaves that are coming through are discoloured, only the bottom leaves on a couple of them.

Thanks.

It does look a little like heat stress but your temps aren't up high enough to do that. You might back the light off further for a while.

Thanks for the feedback Killerweed, when the HPS lamp went in, we didn't have the fan at the time and the temps were getting a bit high. Since we have put it in though the temps have leveled off.

You think these leaves will recover, let the plant do what it needs for them or cut them off? Everything else that is coming through seems to be fine, just those few early leaves.

Also, does anyone use the bio bizz nutes? Are these safe to use every feed (2-3 days apart when soil looks like it needs it) or is is best to use them 1 in every 2/3 feeds?

Thanks.

I'm not sure they needed nutes just yet. It's usually better to give it to them slow in the start, roughly 1-2ml per litre probably every other watering, maybe even every 3rd watering (water, water feed) then building up to the 4ml/litre full dose. Though there are varying opinions on feeding schedules. The plants will "tell" you when they need something and then you get a feel for it.
I use BioBizz (Grow and Bloom) and I think they're good nutes.

The HPS may be a bit close but I think as long as your temps are OK that is probably unlikely to be the issue.

Also do you have any ventilation other than the 4" fan? Extraction/filtration? They like fresh air.

You might want to get a pH tester to keep that aspect in line too. Get a digital or if you are on a budget the manual indicator tester kits are not too bad. If you can afford it, the blue lab truncheons are known to be a great piece of kit.


Perhaps someone who is a bit more tuned in with this kind of thing will pop into this thread, I am still very much new to all this.

Hard to tell from just a pic of low leaves.
Could be nothing more serious than leaves which had been receiving little light being cannibalized by your hungry plant for the N stored thereing when the incerased light intensity from thenew HPS triggered a growth spurt.
Pics of whole plant = more useful.

Many thanks for the feedback PJ and Stinky.

I have a carbon filter hooked up to the extractor and an intake hose, good circulation going through there as if I hold a thin piece of thread next to the intake vent, it gets sucked in. Should be plenty of fresh air being taken in.

I've moved the lights up a tad as the temp monitor I had seemed to be giving funny readings. Got a new one in there and the temps around the plants were varing by about 10 degrees F with this second monitor. It's sitting at about 80 degrees F now.

Thanks for the tip on the ph tester PJ, will be look in to that ASAP. Have been looking at all kinds of devices and from reading other threads, it seems a wise decision to invest a bit of cash in to a decent ph kit.

I will get a few full pics up of the plants next time I have a chance, just sorted them out and all the new growth coming through is nice and green. Yellow/brown colouring of the bottom leaves haven't increased since my original post, so fingers crossed it was either a bit of heat stress or as you say Stinky, lack of a bit of N and the plant had been sucking it in from them.

Thanks again people, help is much appreciated. Will get pics up ASAP.

Cheers.

Hey guys and gals,

Just wondering if someone can confirm for me that this is a male plant (first 2 pics) I've taken it out of the grow room as from all the other pics I've seen, they look like balls. I like the 11 fingered leaf in pic 2 as well, are they normal?

Added a couple of pics of the other 3 I have in there, all confirmed females which I'm very pleased with as this is my first grow, none feminised seeds and have had a couple of small misshaps along the way. I guess I done right in getting white widow for the first grow as they do seem to be very forgiving!!

Anyway, if someone could confirm that the first two pics are a male plant I would be very appreciative.

Cheers!!

It looks like a male to me. But let some others chime in first before chucking it.

[MistaJ]

Thanks GK, I'm pretty sure it is a male, what looks like loads of little nut sacks all over the place so he's now sitting in my kitchen. No chance of pollination as the grow room is in a complete different building.

Cheers for the reply.

Your new growth looks healthy. Don't overwater in that big pot too early, and you're good to go. I see no current problem with that plant. The damage is only on a couple fans and does not appear to be spreading.
