Its in a small toilet space with foilback styro as reflector Space is 2x2x6
If there is anything i forgot to mention ask me ill be happy to answer

wtf is the good in asking questions that never get answeredknowledge is useless if ur the only one that knows it

thanks man the river silt is sandy type dirt that is great for growing tomatoes and can only be got from a place the river used to cover but is drained due to levees and, no i dont ph the water but ill start letting it sit like u say and will repot as soon as possible

You need to ph your water. Ph can lock out nutes cause many other issues that lead to even more issues.

And your issues could very well be ph related. Either from your medium or your water. You can get cheap ph test kits at lowes or anywehre. Ph your water between 6 and 7.

And yes al;so let your water sit out to get rid of the chlorine. But thats totally diff than ph.

thanks man all help is appreciated im going to get a ph tester tomorrow

get a digital meter. The color cheap ones will get you in trouble.....Hanna is good. Ebay has em for about $25. worth it. Get the cleaning and storage fluid...

and the calabration fluid

3 ft 7inches is semi big. It could be rootbound if your pot is too small.

you say your using tap wat ever 3 days!!! thats probally your main problem always use filtered water! have you ever fed them nuts?? a light fresh batch of npk wouldnt hurt at a low dose

either they are starving and you need to give them nitrogen

orrrrrr

its your pH

if the leaves are curling under at the tips and its slightly yellow...then its def. too much water.

its in a 4 gallon square pot but will soon be in reg potting soil in 5 gallon pot

have you been using cal/mag or any dolomite lime. Calcium is essential for any grow as well as magnesium.
What nutes are you using, pH?

p/h is 7.2 to 7.6 thanks for the advice
as for over watering, i think the river silt was holding moisture too long so when i checked it the top 3inches was dry but the center was still wet

Let the soil completely dry, I do it by weight, when the pot feels light water it.

is it gonna hurt to replant it in potting soil in a bigger pot and also i got some EXPERT GARDNER: total nitro 24%, avalible phosphate 8.0%, soluble potash 16%,total copper 0.07%,total iron .15%,molybdenum .0005%,total zinc .06%

i just started 12/12 yesterday

don't transplant to that soil.
You don't want a high nitrogen content for flowering, get some promix and nutes meant for herb.
