Help

I have a clone about 2 1/2 weeks old 10 inches tall in a water farm drip system with 10watt coralife 50/50 10000k bulb 7 inches Away from plant and using distilled water an flora sireas and rapid start my ph is around 5.3-6.0 don't know my ppm my problem is that I have brown tips growing, bottom leaves wilted and mid leave curling upwards with brown on all tips did have a temp and ph problem but fixed it roots died on one side but growing strong on other

using distilled water? are your addin a cal/mag supplement?

yes im using distilled water and no cal/mg supplement

well, hydro not my cup of tea, but the leaf curl indicated a deficiency, i think, i would lower the base nute dose, and add a cal/mag supplement, but id wait for someone more familiar with hydro to chime in

Thanx I'll keep that in mind an others have a thought

It's a potassium def your ph is either under 5 or above 6(double check your ph again) ph in hydro which will lock it out...........adjust your ph accordingly............good luck grower

edit: if your ph is still around the 5.5 and it gets worse then you have a potassium toxicity which will lock out mg and cal which also show those signs....and cold temps will also lock out potassium

How could I fix that

well first how are your room temps/ if too cold raise it........then flush with cocco adjusted ph(5.6-5.9)water double your container size.....and when dryed out give them the cocco nutes at a 1/4 strength(ph adjusted!) and see how they react.....

Room temp is 65-70 what is cocco adjusted ph water

Is that at lights on or off?? meant water ph adjusted for cocco..........when you run straight cocco, it's basically under the guidelines of a hydro system.....you need to make sure your water(ppms/tds/ph) and nutes are spot on......it is NOT as forgiving soil, which is a natural buffer............good luck

Thanx ever one but now Im confused about what's going on its still growing and I'm using rockwool And dose Epsom salt work or should I get cal/mg from gh

That's with light on and fan on then light of is at room
Temp middle of night do like 60

Now I just have a few light green spots the size of pin pricks on the leaves what's that and how do I fix it

I need some pics grower............a closeup of the issue and a pic of the whole plant..........good luck

Now I have a problem with my leaves turning white starting from the center of the leaf

Give some micronutes could be sulfur/iron. really need pics to you will just get guesses.
