Gorilla Cookie Problem

Zuzumanstarted grow question 1y ago

I've been growing plants for eight weeks now. Some have yellow leaves, others have yellow-purple leaves, and many leaves have brown spots. I don't know what the problems are. I'm using Advanced Nutrients Grow, Bloom, and Micro. Grow: 1.5ml/L and Bloom: 3ml/L in 3L of water.

Leaves. Color · Dark-purple

Are you bottom feeding? I'm running into this same issue right now with my grows. It's gonna be salt build up in the soil throwing things off I'm pretty sure. When you use bottom feed method, you need to run some water down the top once a week or every other week to prevent the salt build up. I did not do this and hit issues going into flower also. Looks a lot like this. Feel free to check out my question on potassium deficiency to see the pics. I haven't answered the questions yet, cause no one has given the correct answer and I figured it out through some testing and trial and error. Slurry test showed everything ok. So when I feed it a bit it started to look better I thought, but then tips were burning. Light flush was ok at first, then ph dropped to 4.5 on run off. Salts were dissolving and releasing. Flushed enough to get ph to read 6.4 on run off, but ec dropped to .5 ec. Let dry back and it was worse first day, salts dissolving still not fully flushed, but not changing the second day. Added potassium and magnesium as that's what they appeared to be lacking from liquid fertilizer top and bottom and next day tips were yellowing worse and burning. Added ph'd water next watering from bottom only and plants had very little change to next watering as mine has been slow progressive since flip to . I only have a month or so to go to finish so I'm just gonna ride it out on mine with phd water from bottom. May not be what's going on but looks like it to me. Without more info, that's my best guess. Best of Luck, Happy Growing!

Could guess all day long without a diary, got allllll sorts going on, ec is out of whack means water is not flowing, waters not flowing nutrients ain't moving. Degreening all over.with no obvious starting point is micronutrients which can be common at a high pH of 7 +. Medium has tendency to get a bit wetter during flower, phosphorus requires oxygen to uptake so make sure we are not oversaturated in rootzones, since transpiration is down its all dependent on evaporation until transpiration kicks back in. Ignore purple 💜. Don't blanket feed, feed based off EC. Salts buildup until the ratio gets skewed, once skewed ph will mess things up, pH affects moisture retention by influencing the structure, texture, and porosity of the material in question, whether it's soil, skin, or other substances. When things get too wet or too dry calcium becomes a problem when things get too wet oxygen can become scarsce preventing Phosphorous uptake. For all we know the only problem you have is your running a high rh and you over fed a little. Small problems exacerbated over a period of time. Wish you luck with recovery.

Looks like a nutrient lockout to me, this happens when the pH value is outside the range in which the plant can absorb nutrients. The ideal value for young plants is around 5.8 and rises to 6.5 during flowering. If it deviates too far from this, the plant goes into lockout. If you have the opportunity to measure the runoff, do it and check the pH value and also the EC value, which should be below 2. If the values are not in range, then correct this by watering with pH-adjusted water without nutrients at least 2 times with intervals of 2 days. After that, give it water with adjusted pH and CalMag. Once the runoff is good, you can start fertilizing again, and I would generally always water until water comes out the bottom so that the excess nutrients are flushed out and don’t salt the soil again. Good luck!

100% sure what the problem and 100% how to fix it please listen. Your soil is to acidic the ph is down below 5 maybe even below 4 Take the plant to a bathroom and run like 10 gallons of reg tap water thru the soil if your tap water is between 7 to 8.5 or so that will work it will pull the ph back up in the soil then after wading out the soil with plain tap water make sure to give the plant a few cups of water with nutrients and ph that water to 6.5

Hi, don't get so worked up! I've already brought plants through that I wanted to throw away, and I had a good yield. Give her more nutrients and check your pH, and it will be fine. Check out my last grow.

In the photos, you can see that the plant is suffering from several problems at once: 1. The general yellowing of the leaves and slow growth indicate a nitrogen deficiency and possibly a lack of other macronutrients – especially during the flowering phase. 2. Brown spots and burnt leaf edges can be caused by: • Incorrect pH level - if the pH is off, the roots cannot absorb nutrients, even if they are present. • Cool temperatures (especially at night) can slow down metabolism and disrupt the uptake of potassium and phosphorus. • Waterlogging or poor ventilation: this can lead to fungal infestations, especially in high humidity. What you can do: • Check the pH level of your solution and the drainage water (ideal is 6.0-6.5 in soil). • Make sure that the nighttime temperature does not drop below 18°C. • Check the roots for rot. • Ensure good ventilation. • If possible, lightly flush with clean water and adjust the nutrient supply.

Hard to say without a diary, it's a bit of a blind flight like that. But this looks like typical problems in the late flowering stage. Magnesium deficiency usually shows up first like this, light green between the leaf veins, purple stems, later rust spots. It could also be a bit of potassium or phosphorus deficiency, depending on how long this issue has been going on and how much you've been fertilizing. As long as your pH level is fine and you keep giving flowering nutrients with a bit of extra magnesium, I wouldn't worry too much about it.
