Week 1 (23-29/01)
During this week I will feed the plants with tap water and only 2 ml of Bio-Grow. I will also dimmer the light down to 30% because, being it at 20cm from the plants, I want to avoid burning them. The fan will be on 4 hours/day. By means of the inkbird thermostat I will control the heating/cooling system. Inkbird parameters will be: 23.5°C with -3°C for heating and +2°C for cooling.
23/01 D1: preparing the pots. A layer of gravel surronded by light-mix by BioBizz. Planted the three sprouts.
24/01 D2: added a support to each plant to avoid the fall due to the weight. Provided a glass of fresh water (25cl) to each of them.
25/01 D3: -
26/01 D4: watering day. Added 2ml of Bio-grow to 1.2l of tap water (approximately 40cl of water each plant).
27/01D5: -
28/01D6: watering day. Approximately 50cl of tap water to each plant. Powered on the fan.
29/01D7: -
Today I noticed that one of my plants has an orange/yellow sign on a couple of leaves (see photo with the tag "28/02"). The spots are small and the leaves seem to be healthy (so far). What the problem could be?
You've got a couple of deficiencies here... all caused by two things: the fact that you're using far too much of the BioGrow (causing a nitrogen toxicity which locks out a lot of other nutrients such as calcium and magnesium) and your pH is far too high (you need to get this down to between 6.0 and 6.5). As for the nutes, you should switch the amounts of the BioGrow and BioBloom - i.e., 1ml of the Grow and 2ml of the Bloom - your plants are in flower now and they need far less nitrogen than they needed during veg... BioGrow is going to raise the EC a lot more than the BioBloom so if you're needing to raise the EC with that switch, just add more Bloom to get it where you want it... your plant could use extra P and K as well and this should do that well enough. The damaged leaves will not repair themselves so don't expect to see that... But after a couple of days with the new pH and the new amounts of nutes, you shouldn't see the damage getting worse.
Good luck...
