I thought it might be lack of light but I remember growing dwarf tomatoes in a setup with less light. Those didn't do great but put on fruit and stayed compact.

and the drop test says I have pretty high ammonia/ph so I'm thinking that's the issue?


Drop test:
PH: 7.7~
ammonia: 1.5ppm
No2: very low near 0? /edit I just noticed the no2 jumped up in between test/images so thats high too
No3: 2.5ppm

^tiny tim tomatoes they are suppose to be alot more compact.



I'm pretty sure my main issue is to much fish goo. I hoped the combination of the grow bed/pants and 5 gallon bucket filter was enough for the fish goo but it doesn't seem to be doing the trick so I'm going feed them less and start doing small water changes.

possibly - plants do not like ammonia, and it affects growth.

May the fish sh*t and the plants grow.....

The leaves seem to have yellow spots as well, could it be a manganese deficiancy? Tomatoes are quite well known to devour nutrients........

White spots on plant leaves and very very hard water could just mean it's winter!

Ok it's been a few weeks the plants seem doing better as in slowed down in the stretching and bushed out more.




I'm not sure if it's the:
5%~ weekly water change + sponge filter bucket dumping
skipping one day a week of fish feeding
limiting/keeping track of the amount of the fish food

But one or all of those seem to be doing the trick. The tomato's are still taller then I expected but seems to be bushing out.




As for the yellow spots on the leaves I think that's damage/thin spots from water droplets? When I open the door in the morning there tends to be humility.

Sounds like you need to get some air movement so that the water won't condense on the surface of the leaves. A small fan should help.

What type of light and what wattage were you using back then, and in what sized area?... and what are the LED's you're using now?

I would guess calcium deficiency at this point.

I've got a small clip on fan (6 inches?) in there. I'll try moving it closer to the plants.






Same lights as before I just had them turned off and used the camera flash in the first post.

An unbranded 7band(?) 300w (150 true watt) LED
A DIY 40x1w red/blue
A DIY 12x3w pure blue

so 226~ LED watts over a 3.5ftx3.5ft grow area <- I know people suggest 20+ watts per sq foot and I'm just below that

*Last year~ it was just the 2 DIY's and a two grow bulb from the local store probably half-2/3's the watts/sq ft.






I'm thinking of getting one of those cheap/small dehumidifiers for $30-50 just for the grow box.
