1. Four plants grown from various bag seeds
2. Plants are around 2.5 months old
3. Tallest is 25cm but they have been topped and tied down.
4. 25 liter DWC tub. Whisper 300 air pump with two 30.5cm air stones.
5. AN PH perfect 3-part, Orca liquid mycorrhiza, General Hydroponics cal/mag.
6. Solution PH 5.5-6.5
7. Tap water ppm 25
8. Nutrient solution 597
9. Res temp 15-19 degrees C
10. Ppm normally rises by 5-10 a day for the first few days after a res change then levels out and eventually drops by 5-10 daily as the next change gets closer. Usually changed every two weeks.
11. PH always rises to at least 7 everyday. Sometimes as high as 7.5. It would rise to 8 sometimes during the first few weeks but seems more stable now as plants get older/nutrients get stronger. Adjusting with citric acid PH solution.
12. No foliar feeding
13. One 130watt flurescent bulb 6400k, one 45watt blue/red LED panel.
14. Fluro is 10cm from closest plant. LED is 30cm from closest plant.
15. Space is 100cmX100cm or 9 square feet.
16. Temperature is 14-21C. Relative humidity 45%-65%
17. I saw some gnats while sprouting veggies in potting mix before setting up the DWC. Since then only the occasional moth or mosquito.
18. Beginner level. I have done one outdoor grow in soil. Never done hydro or used bottled nutes before.
I have a grow journal going with some additional info here: https://www.thcfarmer.com/community...ndoor-the-start-of-something-wonderful.95582/
The problem started with dark splotches and yellowing near the tip, but did not start on the tip like I think nute burn would. Then the leaves when crispy and tacoed. I've snipped them off now but I think I have some old pictures if you need to see them. I thought it was cal, mag or P so I upped nutes and added some cal/mag for the first time. I changed the res out and snipped the worst leaves the next day. After I snipped them one plant started drooping, see pictures, and the others started to turn more lime green. Its been 5 days since I changed the res. Some stems are tinged purple, I thought might be cold nights or P deficiency. The symptoms showed up on all plants about the same time. Also the roots look darker than normal, they always had a small amount of brown algae or slime but the root ball was more creamy white. Now they look much more slimey and some parts are very dark, almost black. No funky smell.
I will attach some pictures.
I really appreciate the time you guys and girls put into helping beginners like me.
Thanks.
Peace.
