Hey folks,

I read through all 37 pages and have a couple of questions that I didn’t find through this thread. Does growing with these lights cause one to increase feedings? I’m an Organic growing and will be using Coot’s soil recipe. Will I need to make more teas? Or should the volume of soil need to be larger?
another question is should I only give enough water that is needed and not anymore? I think last time I was dealing with over-watering or at least there wasn’t enough drainage. I was using fox farms and amended with perlite... it seems like Ocean Forest loves to hold on to water. I have scrapped fox farms and perlite. Also if my soil is well amended with calcium do I still need to give it cal-mag?

One Last question I have the double slated HLG 288 V2 lights. It pulls 273w and goes up to 80,000 Lux I don’t or ever have turned it up all the way but I’m growing in a 16”x30”x60” I’m wondering if it is overkill for my cabinet?

I have six seedlings in which are at 2 weeks old today and sitting at 10k lux. What does the range need to be with vegging plants.

I understand these are a lot of questions but with my last grow I just couldn’t figure out what was going wrong. Apparently I had too much calcium which was keeping potassium back... it’s been a whole production and I’m hoping this round will be easier
Any and all help is much appreciated

Hey Tankerous - like the name.
In my experience, growing under LEDs can seem to require a plant to consume more Calcium, and perhaps Magnesium as well, though its important to try to keep the two separate in strategy.

If you have a solid organic mix and enough of it (often its recommended not to go smaller than 7 or 10G for a full term plant), you shouldn't really need to add more top dressings, teas, etc than would be required under any other light - to my knowledge. The plant, being in control in a LOS scenario, will be able to, using root exudes and soil microbiology, adjust the mineral intake to whatever end is required. As long as the mineral balancing is within reason, and the required nutrients are present, you'll be on autopilot.

I have a similar light, a DIY 2x QB288v1 on a HLG-240H-C2100 in a 2x4 - so a bigger area - and for veg i usually run up to about 200-220 watts, but if I flower in there, its turned up all the way.

thank you I got the nick name from my dad because I’m a cantankerous person and my name starts with a D. Right now my seedlings just entered the veg phase and they are in 1gal bag pots. I used a similar soil mix as far as the base goes but not the full nutrients. I’ll be mixing the coot’s mix here in a couple days. I think I’ll veg which ever plant I decide to flower, for a couple weeks in the final pot.
