Hey
I've just started my first DWC grow: https://www.rollitup.org/grow-journals/239368-my-first-ever-dwc-scrog.html
I just realised the tips on the first set of leaves are browning and dying! Surely its not time for them to die just yet???
Also the seedling with the protruding root is drooping I think I may have over watered it (Ill have to stop top-feeding this one cos it obviously doesnt need it!)
...Or is it normal for a plant to be a bit droopy while it acclimatises to DWC, this seedling has about 25-30mm of root in the nutrient.

However it is only the new set of leaves which are drooping the first set are still horizontal but have a small amount of browning on the tips
This one has a small amount of browning on the tips and a little bit along one edge of the first leaves. (These first leaves were a little bit yellow even before I put them into DWC)

As for the brown tips I've done a search and this is what I came up with:
1. The concentration of the new nutrients may be a bit too high at 12-13CF. (Next time I wont add so much Superthrive!!)
But if this is the case it shouldnt get any worse because I will be topping up with straight pH corrected tap-water which will bring the CF down over time?
Is this right? Or should I water it down a bit?
2. Leaving the seedlings in the humidity crib for so long might have caused the leaves to stay wet for long periods?
3. All the formula I have been squirting through the hydroton has left a build up of salts on them which has reached toxic levels?
4. Or I just had them way too close to the fluoro in the propagation area and the browning is from light burn.
5. The temps frequently are around 30 C and the browning is from heat stress.
....Or I am stressing about nothing and they will sort themselves out?
Should I add some H2O2 as a precaution in case of disease?
Any ideas ......Anyone?
