Start small and be patient...what nutes are u using?

im using ionic growth . with ph at 6.0. 3 of plants are fine other 2 are droopy with yellowing and crispyness on ends. ps all differnt strains of autoflower.

All one res?

anything but water + vitamins = nute burn. seeds needs a chance to build the root system before then can successfully take up nutrients. usually till the first set of "true leaves" (personally all i use is superthrive and water till the 2nd set is just about done.

yeah its a 90ltr tank with a custom lid with 5 holes with net pots in. it has a top dripp and two airstones in the bottom .

No Nutes till they have roots , not one little skiny string either. What Bigz said......

you can see the roots coming out of bottom what you think .


HOW FAST DO YOU THINK I SHOULD HAVE THE DRIPP GOING. IT IS AT 1 PER 10 SECONDS DURING LIGHT CYCLE ONLY.

first off they are too young for a HID bulb. get a fluro on them. you can tell you have a highpressure sodium bulb there with those black lines

I just learned this the hard way... they're all pretty much right. Take it "slow and low" with nutes, especially with seedlings.

+1 rep if this helps?

i know i shouldnt have the 600w hps on but its all i got. it is a metre away from seedlings tho.

how long does the plant take to show signs of recovery after nute damage.

those burnt tips will never go away.

day 14 and i have now changed the system to homemade oxy pots. and put clean water in tubs with ph set to 5.8. two of the plants have grown loads and the other 3 dont look so good. what you think.do the big plants need any nutes yet do you think

I tend to wait until I start to see signs of nutrient deficiency before I feed to avoid burning (you can always add more, but you can't take out). That being said, using the GH Flora Series and following their schedule, I have never had a problem with nutes.

Bro you said you have drip system right? maybe the timing if off maybe you need to have water running more often? im not too familiar with drip systems but I run DWC and when I first started i didnt put enought water in the res and my plants looked exactly like yours until the roots found there way to the bottom of the netpot into the res water if that means anything? so basically im saying you might need more water lol
