Spring25 - Auto Apricot & Apple Strudel

Gundermann Everything going well so far. Both plants are about equal in height for now.

Gundermann The tomato plants grew too big and had to leave, so now the girls got their tent for themselves again. I think about starting some LST soon. Up until now i just did some light watering in response to the condition of the soil. I am probably starting proper watering during next week.

Gundermann The girls got their first real waterings with tds and ph controlled tap water (6.2-6.3 pH, 19-21°C, 300-320ppm). pH needed to be reduced with some pH-, yet I managed to slightly undershoot my target of 6.5. Also the LST has begun, so far both respond great to it. For now i just usw some hooks to weigh each stem down.

Gundermann The Girls are doing pretty well so far. They reacted great to LST and grow substantially each day. Therefore I should soon be able to use the scrog net to support plant training. I am uncertain whether I should defoliate them at this point (or ever). Also the Apricot has suffered some tiny yellow tips on several leaves and spots on a single leaf. This was probably the result of reducing lamp height to 30cm for a day. As soon as I spotted the symptoms the distance was restored to about 50cm. Day22: both plants received 1l of pH-adjusted tap water (6.5 pH, 20.1°C, 296ppm) Day26: both plants received 1l of pH-adjusted tap water (6.5 pH, 19.8°C, 432ppm)

Gundermann Both Girls are doing good and started into pre-flowering on day 30 (Apricot) and day 32 (Apple Strudel). So far I am content with the results of the LST. By now I do not have much horizontal space left within the tent, so I moved the scrog net into place shortly after last weeks' entry. Apple Strudel ist doing really well so far. She ja growing fast and showing no signs of any stress or problems. The Apricot on the other hand has some minor problems. For once the branches of the previous top of the plant have eben growing into almost a knot, which I was able to fix by removing a single, albeit a quite large, leaf. Furthermore the Apricot again showed some yellowing and curling of the leaves' tips. I again increased the height of the lamp to combat the yellowing. Still I am uncertain if there is something else i should do, or even if this isn't light stress at all, but some deficiency. This could be the case, as the soil I am using is supposed to be pre-fertilizied for 4-6 weeks. I am thinking about starting fertilizing soon, but I want to do it only when ppm readings drop below suggested levels. Day 30: Both plants got about 2,5l of pH-adjusted tap water (6.5pH, 20.8°C, ~385 ppm). Run-off showed 6.3 pH on both plants. The Apple Strudel had a TDS value of ~980 ppm, the Apricot was at ~1300 ppm. I found some hidden salt buildup from prior use on the bottom of the Apricots'pot, I am hoping its removal will bring the Apricots TDS value back in line with the Apple Strudels'.

Gundermann Disclaimer: The fertilizer values are not accurate. Also I am not doing a real ScrOG, but a autoflower adjusted version using only LST and no defoliation. Both plants are well into flower by now, therefore i will count this week as the first of flowering. On the FastBuds shop page for both strains the expected flowering time is given at 8-10 weeks. As i am not certain if this means total growing time or the actual flowering time, i expect at least another 7-9 weeks from now until harvest. The Apple Strudel has been growing beautiful, I only had to reign in a single branch to even out the canopy so far. Even though the leaves have grown quite dense, no leaves have been removed and I am optimistic that will fix itself by just continuing to grow. The Apricot on the other hand seemed to have gotten a little bit stunted last week, but recovered this week in terms of growth. Also some of the leaves have gotten more yellow and even papery in the tips and edges. Initially i attributed this to light/heat stress. The last few days some of the affected leaf tips started curling upwards, which made me think this might actually be a potassium deficiency? It seemed to have at least slowed down by now. Additionally the Apricots' leaves have grown quite dense (because of which I removed a single large fan leaf before), and I hope that this will now fix itself when she finally stretches some more. As these two are Autos I want to keep any defoliation to a minimum. I have to confess I might have effed up. Because of last week's runoff dropping below 1000 ppm, I decided to cautiously start feeding. Somehow i then continued to feed both plants with all together 1g of Hakaphos Grün (20-5-10(+2)) and 3g of Hakaphos Rot (8-12-24(+4)). But not enough. I actually repeated this mistake yesterday, as i wanted to provide some potassium to the apricot and just realized i wasn't a feeding day. As the most recent run off ppm readings have been quite high (2400 & 3600 ppm) I will stop further feedings until the TDS values have come back down, even though both plants seem actually to be ok. I did some more reading and by now I know for a cautious start I actually should have used a combined 1g per litre at the most at this time. On a positive note my setup has been upgraded with a oscillating fan additionally to the existing static one. Also the LST-clips i ordered weeks ago finally arrived. Day 36: each got 2.5L of water (6.5pH, 22.4°C): 1L fert.-solution (~2360ppm, 3g hakaphos rot, 1g hakaphos grün) + 1.5L water (~380ppm). Apricot runoff at 6.4pH, 2005ppm. Apple Strudel runoff at 6.5pH, 1039ppm. Day 37: Pistils are here. Day 41: The Apricot got 2 L water (1g haka grün + 3g haka rot, 6.5 pH, 21.6°C, 2630ppm) + 0,5 L water (6.5 pH, 21.4°C, 344 ppm), the runoff was at 6.2pH , 2460 ppm. The Apple Strudel got 2 L Water (1g Haka grün + 3g haka rot, 6.5 pH, 21.6°C, 2440ppm) + 0,5l Water (6.5 pH, 21.4°C, 344 ppm), the runoff was at 6.0 pH, 3290ppm.

Gundermann Week 7 was a mixed bag. On the positive side the Apple Strudel had quite a growth spurt and reached almost 60cm in height. She looks quite nice and I hope she continues as is. As the tent is getting quite crowded at this point, the photos do not do her justice. She also shows some signs of nutrient burn which is probably true and I hope to have leviated. Also most of her leaf stems are red by now, which kinda worries me. On the negative side the Apricot continues to have problems. As the yellow edges have stopped increasing it seemed my diagnosis of light/heat stress via LED was right. Yet now she shows some discoloured leaves with rusty spots on them. For me this looks like a cal deficiency from what I can tell by using online resources. Nutrient burn would have made more sense to me, but most recent ppm readings discouraged this. To be honest I am quite confused by what the problem is and how i could fix it. I posted a question regarding this here on gd, but unluckily it got caught in the server hiccup and didnt show for 2 days. So any advice is appreciated. I considered flushing and finally decided on doing a mini-flush (or if you like: half-arsed it), which meant that i gave them more than their usual amount (which is determined by runoff) and instead of allowing the runoff to soak back in, I dumped all of it. Hopefully this provides at least some relief to them, as a full flush would be difficult because of the constraints imposed by pots, net, tent- and plant size. Besides those problems the Apricot seems to be somewhat further into bud development than the Apple Strudle and is already showing increased trichome development. Day 45: Apple Strudel got ~3,4L Water @ 6.5 pH, 19.4°C, 391 ppm Apple Strudel runoff @ 6.2 pH, 1200 ppm Apricot got ~2,8 Water @ 6.5 pH, 19.5°C, 331 ppm Apricot runoff @ 6.3 pH, 1470ppm Day 48: Apricot got some leaf yellowing combined with irregular rust spots. Could be a cal deficiency? Would be a little bit weird because of local tapwater being quite hard. Afaik it is quite unlikely to go overboard with calmag. Therefore the Apricot got 0,5L water with 3ml biobizz calmag @ 6.6ph, 984ppm, 21.4°c. With this little water, there was no run-off. But this volume was about the difference the Apricot was short of the Apple Strudel, so it should even out somewhat. To be honest I also would prefer to water both plants at once, without having to check ph and whatnot every other day. Day 50: Apricot continues to show symptoms. For me this still looks like a cal deficiency (at least from what my online searches tell me). The Apple Strudel starting to show some sign of overfeeding. She got some brown spots on leaf edges, which could be nutrient burn. Would make sense in regards to my accidental overfeeding last week. Apple Strudel got ~4L Water @ 6.5 pH, 19.0°C, 356 ppm Apple Strudel runoff ~0.6L @ 5.9 pH, 1510 ppm * Apricot got ~4L Water @ 6.5 pH, 18.8°C, 352 ppm Apricot runoff 1L @ 6.5 pH, 1180ppm *These values worry me somewhat. I do not understand how the pH could drop below 6 at all, and the ppm value is still quite high. Especially as she didnt get any CalMag.
