First Grow (hopefully Fat) Banana (Auto)

02.06. No water today, probably tomorrow in the morning with nutrients start of the week: - height: 51cm max (3cm/day for the last days) - plant 1: buds fattening; bit pale on top, probably needs some nutrients. (I'll get some Epsom salt as my water doesnt contain too much magnesium) - plant 2: starting to flower - plant 3 not quite in flower, but catching up I think that the second ventilator was a good idea. Humidity stays high 60%+, still very moderate temperatures, around 25°C in the box I will reduce the light cycle to 18/6 for a test and probably increase the light to 80% (212W) later this week xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 03.06. I did mix 9L of light nutrient solution PH 6.8 and did add 12g of Epsom salt to add a bit of magnesium However, the epsom did push the EC to 1.22 and I was too scared and unsure about the right amount of Epsom salt, so I only did apply half of the solution (1L per plant) and then did add 1L of tap water PH:6.2 - will see how the plant react and then there will be the other half in the next watering or another light nutrients without the Epsom The longer night time looks good. When the lighhts went on the plants already did look pretty good. Usually they were quite a bit droopy and had to wake up first plant 2 is stretching a lot. She easily did outgrow plant 1 in height: 53cm atm. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 04.06. No water today plant 2 is still growing, plant 1 more or less stopped xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 05.06 Did mix another nutrient solution without the epsom salt and fed 2L to plant 1+2 without drain in the morning PH: 6.6 EC: 0.68 Coming back from work plant 3 was very thirsty and I gave her 2L of that solution with a few ml of drain... probably have to water her together with the other two now. Plant 1 had a few sick leaves. Brown spots, leaves felt like dry paper. One leaf somehow had a single finger completely dry and crisp. Mostly old leaves at the bottom/sticking to the wall were affected, so I am not overly concerned and just did remove those leaves. The tops of plant 1+2 still are very light greenish. Not sure whether it is because of the fast growth or whether something is missing/off. Lets see how they react to the nutrients and I also did order some real cal/mag... dont trust that epsom salt stuff, mainly because it also contains quite a bit of sulphur and I am very unsure about the dosage as it does push EC a lot... I also finally did increase the light to 80% (212W). This will be the final power. According to the SANLight data sheets more would only make sense with CO2 supplement on 80x80... xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 06.06. no water today the two sick leaves at plant 2 got worse, i did remove them, Made a picture of them together with the leaves that I did remove yesterday besides that, plants did not get worse at least. Buds of plant 1 get thicker, maybe even a hint of trichomes, but not sure about that. plant 2 "only" grew 2cm today, still not a lot of bud development plant 3 had some bud development, maybe trying to catch up to plant 2? xxxxxxxxxxxxxxxxxxxxxxxxxxxxx 07.06. I gave 3L of nutrient solution to plant 1+2 and 2L to plant 3. PH:6.3 runoff plant 1: 250ml EC: 1.26 PH: 5.7 runoff plant 2: 200ml EC 1.16 PH: 5.7 - I think my soil PH is too low. I will water with higher PH next time(s) - EC doesnt look too bad I guess? plant 2 does show magnesium deficiency. For short term treatment I will use a epsom salt foliar spray trying to avoid bud sites in the next dark cycle. But in general I guess I have to fix my PH plant 1 did start with trichome production. At least one good development. welkl besides the fact that I did not get new sick/dieing leaves besides the yellowing xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 08.06. No water today I did mix 0.5L tapwater with 1tsp epsom salt and did use it as a foliar spray at beginning of the dark cycle. Only did spray a little at a few leaves. Not sure whether it had an effect considering how little of the 0.5L I used, but it did leave some residue on the leaves after drying, No fan of epsom salt as foliar spray. Luckily my CalMag did arrive today. next watering probably will be just tap water with calMag and high PH. At least not more signs of deficiencies. I also did rearrange the fans a bit to add some variation in the airflow and to match the growth week closure: some problems with plant 1+2... still didnt really figured out what the problem is. Current assumption: soil a bit too acidic and mag deficiency plant 1 slowly develops her buds and also started to produce trichomes. plant 2 did grow 20cm this week! If she keeps growing I'll get a height problem too... However, her bud sites start to swell a bit, so I hope she is done stretching soon. plant 3 was a weak mutant in the beginning, but now she is my best looking plant - even though she is still lacking behind a bit overall not a very good week. The crazy growth of plant 2 made my canopy uneven and I worry about the yellowing of plant 1 and 2.
