First time grow. Need some help

Hello fellow growers names Eddie. I'm finally doing my first grow after months of doing reading on this site. Ran into a problem hoping you guys can help.. I have gdp tenns that I bought about 2 weeks ago and have been doing great till today. Here's my setup. 4x7x7 room passive intake with a 1000w mh lightaircooled hood with 340cfm inline fan hooked up exhausting the hot air out. Left one side open to suck in all the old air out and cool the hood at the same time. All 3are in FFOC. In 5gallon pots. Temp never exceeds 78f. I water WITH ro water with 1ml calmag. 1ml Hygrozyme 1drop of superthrive per gallon every watering, now the tips are bent down but still looks realy healthy. My friend mentioned N toxity. Since calmag has 2% N and FFOC is loaded already. What you guys think?

Here are some pics... Sorry there not that great

Happy growing

sorry if I'm posting pics wrong

Your running RO water so those tips are not from chlorine or chloromide, that soil should have all the cal it needs for the time being.

If it were mine, I would drop the calmag and superthrive. (I only use that when doing a transplant.) Just use your ph water and see where that takes you.

they look good to me, plants look healthy but are showing obvious signs of being a little thirsty...Since it looks like your growing some clones, dont be afraid to water them more often. Are you using a peat moss mix? Moss commercial grow shop mixes are different mixtures of peat moss, shpagnum, etc..these hold a lot of weight in water and as such contain high amounts of oxygen...the rate of transpiration in your medium highly depends on air movement and plant growth...remember root rot should only be a concern when you "trap" water, sometimes the result of using heartier dense soil. With a peat moss mix give them water and do it often. Dont confuse this with more nutes, keep your feeding schedule as recommended..

I just watered them last night with the same solution. Always at 6.5. Should I wait till next watering or flush it now. Will drop the calmag and St
Until the soil gets used up. Any othe input?

i would not use Super thrive every watering either.

Its not serious enough to warrant a flush. I would hold off on that for now.

I would maintain a feed-water-water rotation in regards to when you should use nutrients. The droop you are seeing is the plant needing moisture...water every day but make sure you have proper ventilation and be sure that the water drains completely and all is left is wet soil, not soaked.

in your most recent picture, I see a bone-dry small clone in the upper half of the photo. punch some holes on the bottom of each soil container and use plastic saucers to catch your run-off water when you feed. over watering will never be an issue and your plants will take off.

Yeah the small ones were due for water when I took the pic.... So you guys recommend me just to use plain ro water at 6.5 and see if it clear a up? I'm using fox farm Of soil

Any more input guys?

easy on the nutes. u have hit the warning track

Oka got it here's the plan. Ima do the rest of the watering just water till he plants use up all the notes in the fox farm.. I'll update in a couple of days at a week max
