1. Are you growing from seed or clones? - seeds 2. How old are your plants? - tomatos are 3 weeks cannabis are 2weeks 3. How tall are your plants? 8ish inches 4. What type of hydro system are you using? dwc 5. What brand/type of nutrients are you using? tomatos are agroponic, cannabis is just using general hydroponics calmag, rapidstart, and orcha so far, adding nutes starting tonight. 6. What is the Ph of your nutrient solution? 6.5 7. What is the PPM/EC of your tap water? I use r/o so 0-10 8. What is the PPM/EC of your nutrient solution? 250ish 9. What is the temperature of your nutrient solution? room temp 10. Does your PPM/EC show a rise or fall when you do your daily PPM check? stays about the same 11. Does your pH show a rise or fall when you do your daily check? no 12. Do you foliar feed or spray your plants with anything? no 13. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights") I use a 90w ufo and a 600w mh 14. How close are your lights to the plants? about 2 ft 15. What size is your grow space in square feet? 5x3 16. What is the temperature and humidity in your grow space? temp around 80, humidity around 20 17. Have you noticed any insect activity in your grow space? found a wood roach, and a big ass spider but other than that nothing. 18. How much experience do you have growing? new to cannabis.
wondering what the cause may be that my tomato leaves are dying? and why the one cannabis leave is wilting/kinda stiff, and the other one has a leave that is kinda curling up on one side.
sorry, I will post more pics later tonight, those ones kind of suck but my lights are off right now so the camera cant focus.
i dont know much about hydro sets up but i belive your ph my be to high.. 6.5 is soil ph range... i belive your suppost to be in the mid 5 range for a ph.. but wait for a hydro grower to jump in
Those spots look like they might be cal/mg deficiency. What ppms are you running your cal/mg at?

250ppm of calmag is my base, I just added veg nutes this week and im running at 520-580 ppms total.
I adjusted the ph when I added veg nutes and it seems like it helped some but the bottom leaves still have some yellow spotting, doesn't seem to be getting any worse though.
So there was only cal/mg at first, now you've added some nutes... sounds like something was deficient. I somehow missed that when I read it. Your plants are big enough to need nutrients if you want them to grow. Once a leaf is damaged it will never recover, you have to watch the new growth and how it responds. You should see a surge of growth now that you've fed them.
Nutrient burn starts at the ends of the leaf. The tips/points turn yellow/brown and it starts to recede down the leaf and you can usually see it coming on unless you torch the plant somehow. Everything else is usually a deficiency of some sort.
If you have the space and time take a tester plant and feed the shit out of it till it dies. Likewise take one and cut out its food supply and watch how they respond. Learn the plants limits on ppm's and see if its worth going to the max before you burn or if you can go with 20% and get similar results.
I've noticed that some novice growers underfeed to avoid nutrient burn and then think they have overfed and burned their plants when they show leaf damage.

yea I think I waited about a week too long to add nutes to my resovoir, and when I did I think the ph was a little to high, I got the ppm dialed in to 500-550 and adjusted the ph to around 5.5 and so far so good, not seeing any progression of the yellow spots or drying of the leaves. heres some up to date pics.
comments, and constructive criticism welcome, these are almost exactly 4 weeks from seed so let me know how they are doing, the smaller on the left is blue mystic autoflower, the bigger on the right is wonderwoman.
Looks pretty good, the stems look nice and healthy green, a little bit of nutrient issues but I suspect those will pass if you feed properly. I think that leaf curling is usually heat related.
