Plant 4 seems to be growing a little bit quicker than all the rest. I snapped a fan leaf on plant 1 while I was doing some LST, not ideal but im hoping she wont miss it. Gave the plants another small dose of nutes.
So I've noticed the tips of my leaves are starting to curl. I'm pretty sure I gave them nutes too soon so I will be laying off nutes for a while.
@LearningasIgrow, To be honest... I really am sort of haphazard with my autos. Usually use them as a bumper crop when the photos move to the Bloom tent... and this is only my third run with autos included. I need to get better at taking measurements, but it'd depend on the week of flower and environmental factors. More light and CO2 equals more transpiration and thus more nutes used by the plant. I'd probably go no higher than 600-800 in early to mid bloom and ramp down. I really just read my plants and use the manufacturer feed schedule as a guide. I usually half or quarter strength my feeds as it is. I need to get a RO system with kdf filter for chloramine, but for now I am running through only kdf filters and still have a relatively high ppm to start... Around 400. So, I am forced to feed at lower strength. Like I said before, I just watch the plants. I don't have it down to a science quite yet, but still getting pretty good results.
@LearningasIgrow, PPM and EC are similar. I only check PPM. EC stands for electrical conductivity, which is a measurement of the ability of something to conduct electricity. In horticulture, EC is the most accurate way to measure nutrient concentration in solution. You don't need to measure both EC/PPM. I am in the states and PPM is more common here, but EC is more common in Europe. I am citing things I have read, and I am no expert. About autos, I have heard they require lower PPM too. I water down my feed with them too.
@Inganjawetrust, Thanks, I've been really happy with them so far. This is my first attempt at growing. I started a couple autoflowers outside around a month ago that I made a bunch of mistakes on. Ive learned a bit from them so hopefully this grow continues to go smoothly.
Everything looks great now. Isn't it amazing how well it does even when we screw up? I've been doing this forever, and a week doesn't go by without me being totally inept at least once!
