Please check the pics and help me. Thanks alot

because it appears to be overdosed

or not enough air flow

1.  I agree with SlimJim.  Some of the leaves exhibit the downward claw, others a bit of yellow-tipping.  Both are possible signs of Nitrogen toxicity, too much Nitrogen.  Cut back on the N-nutes by half if you are feeding them.

 

2.  Your soil:  What soils did you use and what were the mix ratios?  (Or did you use just regular garden soil? which could also introduce soil pests, a subject for another discussion.)  It appears to me that the soil is a little too dense.  Specifically, I see mostly loam, very little Coir or other fluffy fiberous filler in the soil.  Also I see no sandy parts, and I see no Perlite, very important for MJ.  MJ doesnt like wet feet in soil; its roots need to dry a bit between waterings; MJ roots need to have Oxygen.  Continuously wet roots in soil, in worst case, will develop rot and begin to die.  Otherwise, their development is stunted by excess water, which in turn, results in stunted growth of the Vegetation.  It is better to encourage the roots to "seek" the water and nutes.  By seeking water, that is when they extend their roots outward and downward.  When the roots are happy, then the rest of the plant will be happy.

 

3.  I think with your current soil mix being so dense, a daily watering may be too often.  Try watering only every 3 or 4 days.  It may be that you are confusing the "N-Toxicity yellow tips" with "drying-out".  If after reducing the frequency of waterings to improve the roots' conditions, you still believe that the leaves are too dry, you can hydrate the leaves without over-watering the soil by performing foliar misting (about once daily) using clean or distilled water, but with no nutes on the leaves.  Nutes directly on the leaves can result in nute burn.

 

4.  Elvis420 is also correct.  MJ responds well to air circulation because it continuously replenishes the CO2 at the leaves surfaces and creates motion which strengthens the stems.  And exhaust circulation is important to replenish the CO2 in the grow area as well as to control the temps.  30°C is about tops for the temp range desired.  Try not to allow it to get warmer.  A bit cooler would be better.

 

Hope this helps.

And have a good Grow!
