I agree with Cbalderson using a product like hydroguard or Uc roots is almost essential to happy health hydro growing... They are products that create a more stable and healthy environment for your roots.. Also consider blacking out your containers and even maybe the top part as well.. In my experience with LED they can penetrate the claypellets and shine light into the reservoir, very bad. You want your water to be in the darkness depths of hell basically. Just some food for thought but yes I highly recommend using a rootzone enhancer... It keeps your water's PH more stable as well, your ph will always fluctuate but I found after finding a sweet spot of UC roots to water. My water is much more stable requiring very little adjustments and in turn I use less of the ph up and down.. I check ph daily you should too, it's a good excuse to look at your plant. Iv'e had great success with hydro so if you have any more questions leave a comment on my diary. Good luck and happy growing :)

@paparazzi Dump the reservoir Remix your nutes and Extra CalMag and ph it to 6
You'll probably need to keep adjusting the ph back up to 6 periodically as the plant takes up water
I have a plant currently growing Hydroponically that suffered the same issues as well as a Phosphorus deficiency I managed to get the plant back to full health by keeping the ph at 6 as much as I could .

Check roots for root problem. This is the most common thing in hydro and will trigger nutrient defeciency like brown spots and burning of the tips etc... I personally recommend using a supplement called Botanicare Hydroguard for root problems because I’ve used it successfully to get rid of a terrible case of Root Rot. If you are sure it's calcium defeciency in hydro, calcium is best absorbed by the roots in the 6.2 – 6.5 pH range (in hydro, it’s generally recommended to keep the pH between 5.5 – 6.5, but calcium specifically tends to be best absorbed above 6.2)

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.
