I have just started growing hydrophobic 3 weeks ago. About two days ago some of the water got on one of the leaves causing a yellow spot on the leave. A day later(yesterday) I noticed the tips of a few of the leaves turn yellow as well as a few yellow spots on the surface of the leaves. I keep the ph level at 5.5-6.0. Any advice on What may be causing it and how to stop it from continuing? Thank u! IMG_7369.jpeg IMG_2075.jpeg IMG_0806.jpeg I
Yellow tips indicates over feeding with nutrients. Have you used any so far? "Don't let the past remind us of what we are not now." 1000 watt Scrog Journal
Do you have a ppm, TDs, or ec meter? What kind of hydroponic system are you using? "Don't let the past remind us of what we are not now." 1000 watt Scrog Journal
Aha! Here is the key to growing hydroponically in a dwc setup. Ppm TDs or ec meters basically do the same thing differently. You really want one of these for your setup. You can get one that works for about 20-30 $ It measures the amount of total dissolved solids (TDS) or the electrical conductivity (ec) in your reservoir. TDS meters display this information as a value in parts per million (ppm) With one of these meters you can figure out exactly what amount of nutrients to feed your plant and take all the guess work out of it. If you get one, and you should, you then start taking daily readings from your reservoir. Say you add some nutes and then take a reading. The ppm displays as 500. Then the following day you take another reading. The ppm value will shift up or down a lot or a little. If it were to read higher than the previous day you have too much nutrient in your reservoir. If it were to decrease you could add a bit more nutrient to the res. Next to a pH meter the ppm meter is a must have tool for hydroponic dwc growing.

So I just got a ppm meter bad water was at 341. Is this good? Is there a specific number it should be at?
Check it again tomorrow. If the # is higher than 341 add back more water without nutes. Recheck afterwards and then check the next day. If it's less than 341 add back your water and a bit more nutes. Check and recheck the next day. "Don't let the past remind us of what we are not now." 1000 watt Scrog Journal
