Hello good people, I'm growing for 10+ years with no issues under HPS, I managed to go through the whole cycle of veg and bloom without losing a single leaf or having any sort of defficiencies, but it all changed as I recently switched to LED. Now I'm having very hard time to keep the girls healthy. Lights are only thing I changed. I'm also still running one tent under HPS (same strains, same mother) - no issues whatsoever.
I have a number of tents, same setup everywhere, in each tent I have
Thanks for any ideas
I have a number of tents, same setup everywhere, in each tent I have
- 32x 3l coco pots under 2x Lumatek ZEUS PRO 600W in 240x120cm tent
- Clones - ICE and Mazhar
- I'm running these lights at 50% for first few days and then going 100% all the time about 50cm from the tops
- Using Canna Coco and Canna Aqua Veg+Flores+Rhizo+Cannazym
- Also tried Advanced Nutriens - no changes in defficiencies
- Using regular tap water with EC 0.4 pH 7
- Regular IPM in veg - no insects
- Otherwise I do not spray them with anything
- RH is around 40-50% all the time, temps 26°C in daytime and around 20° in the night
- Watering is done by flooding (EBB flow table), by hand in the beginning when they need it and 1x a day in with flood in full veg and flower,
- I'm watering a bit more in veg and a bit less in bloom, but I never go close to wilting
- I water 1 hour after lights switch on and no more that day, so they have time to dry up before next watering
- My pH is 5.4-5.9 in veg and 6.0-6.3 in bloom, also I'm using 2 pH and EC meters for cross-checking values if one of them goes wrong
- EC - tried heavier feeding in the last run (don't have pics) - 1.7 in veg and 2.3 EC in bloom - didn't end up very well, veg was a total disaster, lost more than 50% of leaves, but I switched them to 12/12 anyway and they kinda came back to life and went green
- When I flushed few pots during this horrible run for testing my values in the pots I had EC over 4.5 and pH under 4 in my drain - not ok. In the end - yield was bit lower than I expected, but considering that girls looked like they went through nuclear explosion - it was ok, 1.6g/w
- Lighter feeding is what I'm trying now (pics below) - 1.5 in veg and max 1.9 in bloom (this is week 4 in pics), but I'm still getting this weird defficiences, in much lower scale but I still don't know what is the reason
- I'm also trying to add calmag for this run, seems that it helps a bit
- I'm also noticing, that I have violet stems all the time which is a sign of early N deficiency, but it doesn't seem to change when I change EC at all..
- Its very weird as some girls look perfectly ok and some look horrible.. same strain, same everything...
Thanks for any ideas
